CROSS-REFERENCE TO RELATED APPLICATION 
     This application is filed as a continuation-in-part of U.S. patent application Ser. No. 16/807,767, filed on Mar. 3, 2020, which is a continuation-in-part of U.S. patent application Ser. No. 15/304,588, filed on Oct. 17, 2016, which is a US national phase application of PCT/CA2015/000266, filed Apr. 22, 2015, which claims priority of U.S. Provisional Application Ser. No. 61/982,391, filed on Apr. 22, 2014, the contents of which are hereby incorporated herein by reference in their entirety. 
    
    
     BACKGROUND 
     (a) Field 
     The subject matter disclosed generally relates to methods and systems for optimizing processing power in computer servers. More specifically, it relates to systems and methods for reducing the load on servers during remote operations involving user accounts. 
     (b) Related Prior Art 
     Today, many everyday life actions involve the use of user accounts. For example, various websites involve logging in to a user account for performing transactions. Other contexts, such as the use of membership cars, payment cards, credit cards, etc., permit operations (i.e., financial operations or transactions) which involve user accounts. 
     Various and different methods and systems that provide incentives to buyers and customers (aka purchasers) exist in the context of performing a buying transaction from merchants/sellers of different commodities and services. Most of them provide points or rewards of different types that are credited to a buyer&#39;s or purchaser&#39;s account when a purchase is performed from a pool of merchants/sellers of different commodities and services. By way of example, these points and rewards are preset values related to the amount of the purchase and/or are provided by a random process of selection. Such programs typically involve a multiplication of parties which implies that many user accounts and corresponding data base entries, as well as server queries, need to be performed during a transaction and also beyond the transaction. 
     Some of the technical problems involved in improving such systems are the load on the servers used during a transaction, which can be significant when many transactions are made, providing timely information concerning credits/refunds to user, determining and selecting to which payment cards used for performing the transactions credits/funds should be attributed, determining the structure of the tables of data to be used, distinguishing each transaction (i.e., uniquely identifying each transactions to discriminate them) to be able to perform a selection amongst them, etc. These tasks, which are a technical complexity per se, are also a burden on the servers when a high number of transactions occur. 
     The present disclosure proposes novelties and improvements in this field. 
     SUMMARY 
     In the present description, the terms hereunder can be understood according to and in the context of the definitions given hereto. 
     Operator data and processing server (ODPS-DPS), also referred to herein as a “refund server” or an “Operator data communication and processing server” (ODCPS-DCPS): The server connected to a secure data communication and processing network which is controlled, managed and configured by the operator of the purchase refund system (method) described herein. See, for example,  FIG. 6 , item  610 . 
     Server computer, or server: a computer device, or program on such a device, that provides functionality for other programs or devices, called clients. This architecture is called the client-server model, and a single overall computation is distributed across multiple processes or even on multiple devices for sharing load or according to functionality. Servers can provide various functionalities, often called “services”, such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Servers typically comprise a database, files, and can run applications and communicate over the web. Processing such as computing, the execution of operations, queries/requests by the client(s), preparation of responses, responses to queries to the client(s), retrieval of files, queries of database(s), etc., are all considered as a load for the server, which requires an amount of the limited computing processing power and working memory of the server and consumes energy and computing processing power and working memory in a datacenter/farm/cluster of servers which is also limited. Moreover, several of these operations, especially files and data in databases, require an amount of long-term memory which also requires hardware (memory), consumes energy and space as more devices are required. The server may be a single computer, or is most likely a plurality of computers working together in a single facility or over many facilities, by using cloud computing, where servers work in a delocalized network, virtual servers, server clusters, data centers, etc. 
     Data initiation terminal (aka Merchant terminal/interface): any device with a user interface that is capable of accepting payment from a buyer (i.e., a transaction between the buyer and a seller for goods or services) and accessing a communication network to communicate the details of the buying-purchasing transaction to another computing entity (e.g., a server from a banking institution and an operator data and processing server). The data initiation terminal/merchant terminal may also include web interfaces/pages used for performing online transactions; i.e., ecommerce. See, for example,  FIG. 6 , item  612 . 
     Payment facility/Payment card: the legal and legitimate economic-financial transaction facilities of all types including but not limited to monetary, crypto, currencies, assets, shares, bond, goods, services, payment cards, credit and debit financial capabilities, real and virtual property, patents, copyright, Intellectual, deeds, undertakings and the similar that can be used by legal and legitimate buyers as the means to settle the full value of disclosed assets-sales items by legal and legitimate sellers to transfer the ownership of these assets-sales items from the legal and legitimate sellers to the legal and legitimate buyers. A payment facility also includes a card that can be utilized by a user and accepted by a merchant terminal for a purchase. In the context of this description, the payment card has the capacity to store electronically at least a user ID or any other means to provide electronically information about a purchase account associated to a user. In other instances, the payment card has the capacity to store purchase transaction information and related data. 
     Furthermore, a payment card is associated with a purchasing account and used at data initiation terminal in the process of completing a purchase transaction. 
     Cotemporal: occurring at the same time. Hence, “events which are the most cotemporal” refers to events which are closest to each other on the scale of time. 
     Unique time stamp: a time indicator associated to each transaction and having a precision which is sufficiently such that each transaction has one and only one time stamp associated thereto. The precision therefore depends on the number of transactions occurring within a given period. The greater the number of transactions with a given period, the higher the required precision will be to determine the most cotemporal events; i.e., additional digits after the decimal point to handle increased numbers of transactions accurately. For example, in some embodiments, millisecond precision will be sufficient while in others, microseconds will be required. Yet other embodiments will require nanosecond precision. An example of the use of the unique time stamp is further described herein in accordance with  FIGS. 8, 9 and 10 . 
     Unique key: in database relational modeling and implementation, a unique key is a set of zero, one or more attributes, the value(s) of which are guaranteed to be unique for each tuple (row) in a relation. The value or combination of values of unique key attributes for any tuple cannot be duplicated for any other tuple in that relation. When more than one column is combined to form a unique key, their combined value is used to access each row and maintain uniqueness. Such an example is a concatenated key; that is, a key made from more than one attribute joined together as a single key. 
     Network access device: any device with computing capability and a user interface that is capable of accessing a communication network; e.g., smart phone, tablet, phablet, laptop, desktop, etc. See, for example,  FIG. 6 , item  616 . 
     Owner of a purchasing account: a person or other entity which is permitted to be registered in the purchase refund system described herein. 
     Assets-Sales: Goods, Services, commodities, shares, bonds, deeds, property, real estate, undertakings, commitments, agreements, contracts, receivables, tokens and any other and all tangible and nontangible items which have legally and legitimately well-defined values and are legally and legitimately owned and possessed by legal and legitimate entities who have publicly disclosed the assets-sales and to transfer of ownership by legal and legitimate ways, disclosing their specification and values through dedicated means, media, news, websites applications and other public facilities and capabilities, who are Legally and legitimately authorized to trade, sell and transfer the property and ownership of these items by implementing legal and legitimate economic-financial transactions to legally and legitimately transfer the ownership of these assets-sales to an another legal and legitimate entity, other than the seller, who is prepared to legally and legitimately accept to become the legal and legitimate owner and possessor of the offered assets-sales items. 
     Transfer of property and ownership: The legal, comprehensive and legitimate undertaking to exchange the legal and legitimate ownership of an asset-sales items from a current legal and legitimate owner of the asset-sales items to himself or his legal and legitimate assignees other than the entities who are the initial legal and legitimate owners of the assets-sales items disclosed for sale by implementing legal and legitimate economic-financial transactions that cover the offered value of the assets-sales items in settlement of the full and final values of the disclosed assets-sales items as agreed between a legal and legitimate seller and a legal and legitimate buyer. 
     Buyer/purchaser: any legal and legitimate entity who is legally and legitimately authorized and is capable to buy and settle the full value as agreed by himself or his authorize assignees and legal and legitimate sellers through economic-financial transactions to transfer the ownership of the assets-sales items as disclosed by the legal and legitimate sellers of these items who are the legal, legitimate and authorized owners and legal and legitimate sellers of the disclosed assets-sales items.

     DETAILED DESCRIPTION 
     As mentioned above, many everyday life actions involve the use of user accounts typically embodied as accounts stored in a database on a server. Various websites involve logging in to a user account for performing transactions. Other contexts, such as the use of membership cars, payment cards, credit cards, etc., permit operations (i.e., financial operations or transactions) which involve user accounts. Operations are performed remotely, where the user is not located by the server in which the user account data are stored, nor is he or she located close to the server in which the operations involving the user account are performed (since such a server may be different). More specifically, it is likely that more than one server in view of the popularity of cloud computing, server clusters, data centers and the like. A server can therefore mean (i.e., be the functional equivalent of) a plurality of servers working together. 
     As a specific example of uses which involve user accounts and which are not necessarily involving a login to a website, there are incentive programs to buyers and customers (aka purchasers) which exist in the context of performing a buying transaction from merchants/sellers of different commodities and services. Most of them provide points or rewards of different types that are credited to a buyer&#39;s or purchaser&#39;s account when a purchase is performed from a pool of merchants/sellers of different commodities and services. By way of example, these points and rewards are preset values related to the amount of the purchase and/or are provided by a random process of selection. Such programs typically involve a multiplication of parties which implies that many user accounts and corresponding data base entries, as well as server queries, need to be performed during a transaction and also beyond the transaction. 
     For example, the transaction may involve the actual transaction, whether in-store or on the web, where the user gives a payment card, debit card or credit card containing a chip or magnetic band to perform the transaction using the card. In addition to the use of that card for payment, another card can be used for the incentive program for the accumulation of points. It means that the transaction involves, from the point-of-sale (POS) system, a communication of information to the server of the payment card (or equivalent thereof), and an additional communication of information to the server of the incentive program. Each of these two different parties need to maintain their own server, which comprise a respective user account for the same person, and communications (typically bi-directional, as confirmations are needed) need to be made to both servers for a single transaction. After completion of the transaction, the user may even use the points awarded in the incentive program to make purchases of predefined items in participating merchants, where additional accounts need to be made as the managers of the incentive program need to create user accounts on their servers for the merchants (in addition to the customers) to account for the merchandise sold by the merchants to the customers via the incentive program, thereby adding a certain number of user accounts in the database of the servers and also adding a significant number of server operations. 
     Some of the technical problems involved in improving such systems are the load on the servers used during a transaction, which can be significant when many transactions are made. Moreover, in view of the remote operations involving user accounts, such as transaction, it is critical to provide timely information concerning specific data of the remote operations, such as credits/refunds to user, determining and selecting to which payment cards used for performing the transactions credits/funds should be attributed, determining the structure of the tables of data to be used and maintaining updated data in the database, distinguishing each transaction (i.e., uniquely identifying each transactions to discriminate them) to be able to perform a selection amongst them, etc. These tasks, which are a technical complexity per se, are also a burden on the servers when a high number of transactions occur. 
     The present description proposes a system and method to optimize, and even reduce in comparison with other methods such as the typical incentive programs, the load (processing power, working memory, memory on the servers, database queries and quantity of stored data) on the servers for making remote operations involving user accounts. The example of transactions involving an incentive reward program is giving as a suitable example where the proposed method is manifestly useful. 
     Processing such as computing, the execution of operations, queries/requests by the client(s), preparation of responses, responses to queries to the client(s), retrieval of files, queries of database(s), etc., are all considered as a load for the server, which requires an amount of the limited computing processing power and working memory of the server and consumes energy and computing processing power and working memory in a datacenter/farm/cluster of servers which is also limited. Moreover, several of these operations, especially files and data in databases (user account database entries, transaction entries), require an amount of long-term memory which also requires hardware (memory), consumes energy and space as more devices are required. 
     From a computer hardware perspective and in view of the significantly high number of remote operations performed using servers nowadays, such operations need to be made in a more optimized manner to ensure that the load on the server is kept at a reasonable level, to allow scaling without having to add several server computers uselessly to perform unoptimized tasks. 
     In practice, in addition to the technical advantage (i.e., reducing the load on the server) obtained from the method, the method and system running the method can be used to enhance sales, by providing a full refund or a multiple of the value of a purchase transaction, to eligible buyers/owners from selling accounts, thru the use of a program, which is executed in selected time intervals on a daily basis or otherwise. Alternatively, the program, or algorithm, can be executed in multiples or fractions of an hour during a calendar day within geographical (time) zones on a given territory (e.g., the USA). In other embodiments, it would be applied on a world-wide basis. 
     Based on simple market economics, the method is presented in the following paragraphs. 
     The market&#39;s (economics) simplest theory is the availability of a supply and a demand. The basic interest of any purchaser/buyer is to get benefit of his purchases, whether in the form of monetary funds, goods, commodities, services, bonuses, rewards, cash back, loyalty points, points for air mileage, and points for purchasing gas being common examples of this fact. The basic interest of the merchant/seller is to increase (in quantity and value) his sales and revenues. 
     The mediums of credit-debit, online, e-commerce and/or similar payment methods available in the prior art, except cash, charge certain fees, which the buyer ends up paying and, in some applications, getting the benefits of his transaction in the form of rewards, points and few cash-back percentage points applied on a selected pool of merchants/sellers and not on all purchases but on some selected groups, services and/or commodities. 
     An objective of this program is to provide the opportunity of a refund that fully covers the value of the purchase price and, in particular embodiments, even refunds that can cover the multiples of the purchase price. The refund objective is in the form of a monetary refund and will encourage the buyer to use this medium more than the presently available refund services as explained above. 
     The direct consequence of this advantage, i.e., monetary refund, will enhance the sales at an outlet/merchant/seller/point of sale using this facility, as compared to those who do not provide it. Consequently, the basic theory of supply and demand will be energized. 
     Application Example 
     The following steps form part of an example according to an embodiment:
         1—Provide the monetary refund facility, thru available technology, such as payment cards, online transaction, smart phone transactions, etc.   2—Register all buyers/owners of purchasing accounts in the system thru and in a purchasing account identification package, which includes as a minimum, name, account number, nationality, date of birth, gender, profession, address, mobile number, email, ID (identification) number, etc. (see  FIG. 2 ). Each buyer has a single user account for the payment and the incentive reward program considered altogether.   3—Create points of sales, either by using available data initiation terminal/merchant terminal and/or introducing new data initiation terminal/merchant terminal belonging exclusively to this application (see  FIG. 1 ).   4—Allow buyers/owners of purchasing accounts to deposit monetary funds in their purchasing account (see  FIG. 3 ).   5—Allow the sales through the data initiation terminal/merchant terminal in point  3  above (see  FIG. 4 ).   6—Register the details of the purchase, i.e., point of sales, value of purchase, date, time, etc. (see  FIG. 4 ).   7—Segregate the details of the purchase (see  FIG. 4 ).   8—Deduct from the purchasing account of the merchant/seller, in monetary form, certain percentage points of the total sales of the purchase transaction, and deposit the total accumulations of such monetary values of the certain percentage points in a pool of funds (TRUST) (see  FIG. 5 ).   9—Split monetary purchase value of the purchase transaction into merchant&#39;s/seller&#39;s monetary earnings and the monetary value of the certain percentage points. Transfer merchant&#39;s/seller&#39;s monetary earnings into his selling account; and deposit the monetary value of the certain percentage points (the fees) in a separate account for the pool of funds (TRUST) belonging to the system operator/developer (see  FIG. 5 ).       

     Monetary Refund Mechanism: 
     According to an embodiment, the refund to eligible purchasers/buyers/purchasing account holders is deposited in the purchasing account of the owner thereof from the monetary funds of given accumulation periods and deposited in the pool of funds (TRUST) is performed as described in the following paragraphs. 
     The individual refund monetary value of eligible buyers will come from the BALANCE which is defined as being the difference between total deposits (TRUST) and the costs (COST): 
     
       
         
           
             BALANCE 
             = 
             
               TRUST 
               - 
               
                 COST 
                 . 
               
             
           
         
       
     
     The costs include, but are not limited to, operational and management costs, legal expenses like taxes or otherwise, reasonably legal profits and alike. The costs are paid to the operator/developer of the system. 
     Consequently, the objective of this scheme is to refund the BALANCE to the eligible buyers/purchasing account holders. 
     The diffusion/attribution will be performed based on time intervals (aka given accumulation period), which can be multiples or fractions of hours, during one calendar day or otherwise. Such criteria can be reconsidered from time to time. Alternatively, the program, or algorithm, can be executed in multiples or fractions of an hour during a calendar day or otherwise within geographical (time) zones on a given territory (e.g., the USA). In other embodiments, it would be applied on a world-wide basis. 
     According to an embodiment, eligible refund buyers will be the buyers of the first refund time or second refund time of a given refund time in the forward and backward time order according to the relevant time stamp or similar and/or other similar algorithms of similar or distinct time intervals or other applications. 
     According to an embodiment, refund policy can be subject to change based on holiday period, occasion, and promotional packages. 
     According to an embodiment, the total diffusion/attribution/refund of each time interval will be made to the number of eligible buyers/purchasing account holders such that the BALANCE in the given refund time interval is zeroed; i.e., if the balance is x dollars and the number of eligible buyers to a refund, or other algorithms, is such that the x dollars is completely diffused as full refund of the transactions, then the total number of the eligible buyers to a refund, or other algorithms, are identified, and accordingly the total number of eligible buyers can be any number such that this number exhausts/diffuses the BALANCE available of the given refund time interval. 
     The attribution of funds to purchasing account holders is illustrated by the following particular example of the eligible buyers to a refund. If the balance contains $1,000, such balance will be diffused equally between the eligible buyers of the forward time order and the backward time order of a given refund time to a refund associated to a time stamp, 50/50, i.e., $500 to the eligible buyers of the forward time order of a given refund time and $500 to the eligible buyers of the backward time order of a given refund time, such that the first $500 will be diffused to any number of eligible buyers of the forward time order until the first $500 is zeroed, and the second $500 will be diffused to any number of eligible buyers of the backward time order until the $500 is zeroed for the selected given refund time of the interval of time associated to time stamps applicable to this algorithm. 
     According to an embodiment, the daily transactions information (or at another frequency established by the operator) will be available to the public on a daily basis or otherwise and accessible to everyone thru a dedicated website, social media sites, mobile applications and the like. The transactions information will provide total number and value of purchases showing the progress of accumulation of the BALANCE available for diffusion for each time interval. 
     According to an embodiment, eligible buyers will be notified of their winnings thru a dedicated website, social media sites, mobile applications, text messages, emails and/or the like upon the completion of the eligibility process. The eligible buyers will be credited the full value of their refunds in their purchasing accounts within the program. 
     According to an embodiment, the list of actual eligible buyers for each time interval thru any algorithm will be made available thru a dedicated website. The daily transactions information will be available to the public on a daily basis or otherwise, accessible to all thru a dedicated website, social medias, mobile applications and the like. The transaction information will provide total number and value of purchases showing the BALANCE available for diffusion of each time interval.

     The operator data and processing server  610  is for providing a refund to an eligible purchasing account, in which monetary funds are held, for a purchase made at a purchase price at a specific time to which is associated a time stamp. The operator data and processing server  610  comprises: a memory (not shown) for storing data and instructions; and a processor (not shown) in communication with the memory. The processor is for executing the instructions. The instructions comprise the steps of: receiving a portion of the purchase price in a pool of funds, defined as a trust; and determining the refund to be transferred from the trust to the eligible purchasing account based on the time stamp, the refund covering at least a part of or, on given occasions, a multiple of the purchase price. According to separate and distinct embodiments, the instructions also include the other steps, in combination or individually, of the method for providing a refund described herein. 
     The Following Paragraphs List Advantages of the Presently Described System and Method:
         1—All payment cards, which provide rewards like loyalty points and cashbacks, do not refund the full monetary value and the possibility of the multiples of the value of a purchase transaction.

The information can then be communicated/transmitted back officially to interested parties with the objective of enhancing the interest of all related parties.       

     Now turning to  FIG. 7 , a method  700  for automatically and/or systematically transferring, storing and exchanging funds data between payment cards, merchant terminals and an operator database according to an embodiment is disclosed. It should be noted that the funds data concern transactions performed using the payment cards and that each one of the payment cards has associated thereto a card ID (identification), a payment card account and an amount of funds available for performing transactions. 
     The method  700  is implemented on an operator data and processing server (see  FIG. 6 ) which performs the steps detailed below. 
     In step  702 , a table of transaction data is created in the operator database. The transaction data results from the use of a plurality of the payment cards at at least one of the merchant terminals which generates the transaction data. The transaction data includes, for each use, a transaction ID (identification), the respective card ID, a number representative of the value of the transaction and a unique time stamp representative of a specific time at which the use took place. According to an embodiment, the use takes place within a given accumulation period which comprises multiples or fractions of hours during one calendar day. In this example of the table of transaction data, the transaction ID is the unique key that is used to ensure each transaction is uniquely identified. 
     In at least one embodiment, the transaction data is generated as a result of (in response to) reading of the data of the payment card by the merchant terminal. Such reading of the payment card  605  may be executed by various technologies, such as, for example, by radio-frequency identification (RFID) or near-field communication (NFC) technology. The unique time stamp is generated at the exact moment of reading of the data from the payment card. The merchant terminal  612  comprises a merchant terminal processor and an input element, such as, for example, a merchant terminal keyboard, a merchant terminal display, and/or a merchant terminal touchscreen. 
     Alternatively, the transaction data  1132  ( FIG. 11 ) may be generated at the merchant terminal  612  as a result of (in other words, in response to) receiving an input of the payment card number at the merchant terminal  612 . The unique time stamp, which becomes part of the transaction data, may be generated by a merchant terminal processor of the merchant terminal  612  at the moment when the merchant terminal  612  receives the number of the payment card (for example, right after the “OK” button of the terminal is pressed on a keyboard or on a touchscreen of the merchant terminal  612 ). The transaction data  1132  is then transmitted to the refund processor  1110  of the refund server  610 . It should be noted that the merchant terminal  612  can be a physical device in certain embodiments while in other embodiment (e.g., for online transactions), it can be referred to as a merchant interface. 
     According to an embodiment, the details of the purchased item and associated data form part of the transaction data stored in the operator database. 
     In step  704 , trust numbers are calculated by applying a percentage that is less than 100% to each number representative of the value of the transaction. 
     In step  706 , all the trust numbers within the given accumulation period are summed thereby defining a trust account amount. 
     In step  708 , a balance amount is calculated by applying a percentage that less than 100% to the trust account amount. 
     In step  710 , a table of sequenced transactions by transaction ID is created in the operator database. The sequenced transactions are ordered according to their respective unique time stamp within the given accumulation period. As for the table of transaction data, the unique key for the table of sequenced transactions is the transaction ID according to an embodiment. 
     In step  712 , a subset of the sequenced transactions is selected. The subset is selected starting from a first transaction in the sequenced transactions, the first transaction being the most cotemporal to the given time, and ending with a cut-off transaction which is the transaction where the sum of all the numbers representative of the value of transactions, for the transactions between and including the first and at least a portion of the cut-off transaction, is equal to or more than the balance amount. 
     In step  714 , a table of the subset of the sequenced transactions is created in the operator database. The table of the subset of the sequenced transactions comprises the transaction IDs and the corresponding number representative of the value of transactions for each transaction of the subset of the sequenced transactions. As for the table of transaction data, the unique key for the table of the subset of the sequenced transactions is the transaction ID according to an embodiment. 
     In step  716 , the corresponding numbers representative of the value of the transaction are respectively added to the amount of funds associated to the payment cards which correspond to the transactions in the subset of the sequenced transactions within the given accumulation period. 
     According to an embodiment, the steps of selecting a subset of the sequenced transactions (step  712 ), creating a table of the subset of the sequenced transactions in the operator database (step  714 ) and respectively adding each corresponding number representative of the value of the transaction to the amount of funds associated to the payment cards which correspond to the transactions in the subset of the sequenced transactions (step  716 ) are performed after the given accumulation period. 
     According to an embodiment, the steps which are performed after the given accumulation period (e.g., step  712 ,  714  and  716 ) are performed in less than 5 minutes. According to an embodiment, the steps which are performed after the given accumulation period (e.g., step  712 ,  714  and  716 ) are performed in less than 1 minute. According to an embodiment, the steps which are performed after the given accumulation period (e.g., step  712 ,  714  and  716 ) are performed in less than 10 seconds. According to an embodiment, the steps which are performed after the given accumulation period (e.g., step  712 ,  714  and  716 ) are performed in less than 1 second. According to an embodiment all steps of the method performed after the given accumulation period are performed according to the periods set out above. According to an embodiment all steps of the method are performed according to the periods set out above. 
     According to an embodiment, the number of transactions involved in the steps of the method within a given accumulation period is more than 3,600. According to an embodiment, the number of transactions involved in the steps of the method within a given accumulation period is more than 10,000. According to an embodiment, the number of transactions involved in the steps of the method within a given accumulation period is more than 100,000. According to an embodiment, the number of transactions involved in the steps of the method within a given accumulation period is more than 1,000,000. The number of transactions being potentially very high, it is technically advantageous, in terms of server usage and optimization of the usage, to ensure that transactions entries have the double effect of performing not only the financial transaction itself, but also providing the eligibility to the incentive reward program, at the same time (i.e., the payment in itself, alone, provides both effects). Each financial transaction also acts as a contribution to the reward program (i.e., the portion of the amount transferred to the fund). 
     According to an embodiment, the rate of transactions involved in the steps of the method is more than 1 per second. According to an embodiment, the rate of transactions involved in the steps of the method is more than 10 per second. According to an embodiment, the rate of transactions involved in the steps of the method is more than 100 per second. According to an embodiment, the rate of transactions involved in the steps of the method is more than 1,000 per second. 
     According to an embodiment, the foregoing steps performed by the operator data and processing server are performed without human intervention. By performing the steps disclosed herein, the operator data and processing server becomes a special purpose server; i.e., one performing functions which no other server has performed before. The operator data and processing server is therefore essential to the method described herein. 
     According to an embodiment, the performance of the method by the operator data and processing server covers a particular application of the addition of the value of a transaction to the amount of funds associated to the payment cards which correspond to the transactions in the subset of the sequenced transactions. According to another embodiment, the performance of the method by the operator data and processing server covers a particular application of a method of processing a refund. 
     Furthermore, because of time constraints and the number of operations involved in performing the method for a high volume of transactions, it would neither be useful nor practical to perform steps by a person or a team of persons however large the team would be. The shear coordination problem related to updating the tables of data, calculating, summing and updating the amount of funds associated to the payment cards would render the task impossible. 
     According to an embodiment, the selecting of the subset comprises selecting sequenced transactions according to at least one of: a forward time order of the purchases; and a backward time order of the purchases. 
     According to an embodiment, the given time comprises a first time and a second time, wherein a first portion of the balance amount is attributed to a period starting from the first time and a second portion of the balance is attributed to a period starting from the second time. 
     According to an embodiment, a first portion of the balance is used in the adding step from the first time according to a forward time order and a second portion of the balance is used in the adding step from the second time according to a backward time order. 
     According to an embodiment, the first time corresponds to a beginning of the given accumulation period and the second time corresponds to an end of the given accumulation period. 
     According to an embodiment, the first portion of the balance amount and the second portion of the balance amount are equal. 
     According to an embodiment, the method further comprises remotely accessing, for each one of the payment cards, the payment card account for recording and validating the amount of funds available for performing transactions. 
     According to an embodiment, the method further comprises adding the trust account amount of each accumulation period to a trust account. The trust account is separate and distinct from the payment card account and is inaccessible by a user having access to the payment card account. 
     According to an embodiment, the method further comprises, before adding the corresponding numbers representative of the value of the transaction to the amount of funds associated to the payment cards, identifying, based on the transaction ID key in the table of transaction data, the respective card IDs and the associated amount of funds available for performing transactions. 
     According to an embodiment, the method further comprises receiving from a plurality of the merchant terminals the transaction data over a secure communication network. 
     According to an embodiment, the method further comprises associating the respective card IDs to respective users having previously associated an address of a computing device to the respective user and sending a notification to the computing devices advising the respective users that the adding the corresponding numbers representative of the value of the transaction to the amount of funds associated to the payment cards took place. 
     According to an embodiment, the given accumulation period comprises multiples or fractions of hours during one calendar day. 
     Now turning to  FIGS. 8, 9 and 10 , a transaction data table  800 , sequenced transactions table  900  and a subset of the sequenced transactions table  1000  are respectively shown. According to an embodiment, the foregoing tables are created in the operator database (not shown) which is part of, or at least in communication with, the operator data and processing server (see  FIG. 6 ). 
     According to an embodiment, the transaction data table  800 , sequenced transactions table  900  and a subset of the sequenced transactions table  1000  all have the same columns: Transaction ID column  802 , Time Stamp column  804 , Card ID column  806 , Number (value) column  808  (e.g., dollars), Accumulation Period column  810  (e.g., one-hour periods) and Date column  812  (e.g., yyyymmdd). 
     As stated earlier the transaction data table  800  results from the use of a plurality of the payment cards at at least one of the merchant terminals which generates the transaction data. In this example, the transactions are in no particular order. Transaction ID 1 and 3 are performed using the same Card ID (X123) within two distinct Accumulation Periods on the same Date and at distinct and/or at the same merchant terminals. 
     The sequenced transactions table  900  shows that the transactions are reordered (i.e., sequenced) according to their respective time stamp within a given accumulation period. Accordingly, the date of the transactions is also used when reordering the transactions. In this example, all transactions are performed on the same date. This example now shows that the transaction sequence with a given accumulation period (e.g., 0800 to 0900 which represents 8 am to 9 pm on May 1, 2015) is 1, 2, 4, 7, 5, 6. Transaction 3 is not in the list since it occurs in a different given accumulation period. 
     The subset of the sequenced transactions table  1000  shows that only three transactions (7, 4 and 2) remain. In this example, the given time is 0815 and the balance amount is calculated to be 4,912.74 in view of all the transactions made during the accumulation period. This exemplary balance amount (4,912.74) is obtained from the trust which is generated by applying a certain percentage, say 4%, on a hypothetical value of 205,072.50 being the sum of the value of transactions within a given accumulation period (i.e., the sum of all the numbers representative of the value of the transactions within a given accumulation period) yielding a value of the trust equal to 8,202.90 to which another percentage is applied, in this case 60%, to generate the balance which in this case becomes 4,921.74. 
     The transactions are first reordered (re-sequenced) starting with the transaction ID which is most cotemporal to the given time. In this case, transaction ID 7 is the most cotemporal to 0815. The next is transaction ID 4 and then transaction ID 2. The next one would have been transaction ID 1 which took place 2 ms before transaction ID 2 and therefore is less cotemporal to 0815. The cut-off transaction is identified in this example as being transaction ID 2 since it is the transaction where the sum of all the numbers representative of the value of transactions, for the transactions between and including the first and at least a portion of the cut-off transaction (i.e., 613.98+25.76+12,244.02=12,883.76), is equal to or more than the balance amount (i.e., 4,912.74). 
     According to other embodiments, supplementary criteria are added to reorder the transactions. The supplementary criteria could be to limit the reordered transactions to those which are after the given time or, alternatively, to those which precede the given time. 
     This example further shows that the value of the transaction which are respectively added to the amount of funds associated to the payment cards which correspond to the transactions in the subset of the sequenced transactions are as follows: “613.98” is added to the amount of funds in the account associated with payment card Z730; “25.76” is added to the amount of funds in the account associated with payment card Z224; and “4,273.00” is added to the amount of funds in the account associated with payment card X159. In this example, 4,273.00 is the amount which remains from the balance amount once the first two additions to the amounts of funds in the accounts associated with payment cards Z730 and Z224 are performed (i.e., 4,912.74−613.98−25.76=4,273.00). Therefore, for the cut-off transaction, 7,971.02 of the 12,244.02 will remain unpaid. According to another embodiment, the system operator could decide to fully refund the entirety of the cut-off transaction or, to the contrary, not reimburse the cut-off transaction since it cannot be fully refunded. 
     Now referring back to the initial goal of the method, it can be appreciated that the method described above involves far less server operations, and therefore optimizes the load on the server, in comparison with other methods of associating an incentive program account with a specific transaction. The payment acts, alone and only by itself, as an action both performing a financial transaction and providing eligibility to the incentive reward program. Database table entries for both the user accounts and the for the financial transactions are reduced by two, compared to a typical situation where the reward card is distinct and separate from the payment card, reducing server usage. 
     Considering that the number of transactions can be significantly high, the method described above involves a smaller number of parties, by eliminating the need for all servers managed by an incentive program provider. The user account first created for the payment card is the same (no redundancy) as the user account for the incentive program provider since, in the present invention, there is no distinct incentive program provider in addition to the payment card provider. This means that from a user perspective, less operations need to be made. From a manager perspective, the same is true. Finally, it is clear that there are less databases required since the number of user accounts and the required memory is approximately cut in half. 
     Moreover, as mentioned above, during a typical transaction involving an incentive program, there are remote communications with the servers of both parties (both providers). In the present case, there is a single provider, with a single communication required from the point-of-sale system. Communications are reduced. It means that server queries, the computing processing resources for preparing a response, and the response from the server to the client are in reduced number (divided by two). 
     Moreover, since the refund of the incentive program is in the same currency as the financial transactions, there is no need for a catalogue where the incentive points would be used, and also no need for maintaining user accounts of the incentive program provider for the merchants offering merchandise for purchase in such a catalogue. Therefore, there is no need for a database comprising product data, and no need for a database comprising data on the merchants and data on the business performed within the catalogue of the incentive provider, thereby saving memory for such unneeded databases and also saving on the server operations that are not performed when compared to traditional incentive program providers. 
     From a modern perspective where server computer processing power and memory are often shared over multiple servers (cloud computing, servers, data centers, etc.), the reduction of operations and the reduction of required memory lower (i.e., optimized) the load on the servers for running the method when a great number of transactions are made. The remote operations therefore have a reduce load on the servers (or on the single server if there is only one). 
     Referring now to  FIG. 11 , shown therein is a block diagram showing the system  1100  for refunding funds to a user account, according to at least one embodiment of the present disclosure. The refund server  610  comprises a refund processor  1110  and a refund computer-readable memory  1112  of the refund server for storing instructions to be executed by the refund processor  1110 .

The user account database entries described above of the user account data are stored in a user account database  1120 . The pool of funds is accumulated in the trust account  1130 . 
     The refund server  610  is linked for data communication to merchant terminals  612  which are remotely located from the refund server  610 . The merchant terminals  612  are configured to collect data from payment cards  605  during each transaction when one payment card  605  is read by one of the merchant terminals  612 , each payment card  605  having a card identification (ID) associated to the payment card  605 . 
     The transaction data described above is stored in a transaction database  1115 . The transaction database  1115  may be located in the refund server  610  or, alternatively, the transaction database  1115  may be located remotely from the refund server  610  and communicate with the refund server  610  via the network  614 . As described above, each transaction data is associated with each transaction performed between the payment card  605  and a merchant terminal  612 . 
     The system  1100  also comprises a notification server  608 , linked for data communication to the refund server  610 . The notification server  608  comprises a notification processor  1162  and a notification computer-readable memory  1164 . 
     The system  1100  may also comprise the operator web server  606 . The operator web server  606  comprises a web server processor  1172  and a web server computer-readable memory  1174 . 
     The refund server  610  may communicate with the notification server  608 , the operator web server  606  via the public networks  614 . The merchant terminals  612  communicate with the refund server  610 , and in particular with the refund processor  1110 , via the public networks  614 . 
       FIGS. 12A-12B  illustrate the method  1200  for refunding funds to a user account, in accordance with the embodiments of the present disclosure. 
       FIGS. 13A-13B  illustrate a flow diagram of the method  1200  for refunding funds to a user account, in accordance with the embodiments of the present disclosure. The method  1200  is described herein with reference to  FIGS. 11, 12A, 12B, 13A,13B . 
     At step  1302 , the refund processor  1110  generates entries of user accounts in the user account database  1120 . Each one of the user accounts in the user account database  1120  is associated to one payment card  605  of the user. Each entry of the user account comprises an amount of funds available for performing transactions. Each one of the payment accounts is associated with a main user device  616   a.    
     In the user account database  1120 , each entry of the user account comprises an identification of a main user device  616   a . The information about this main user device  616   a  may comprise at least one of an Internet Protocol (IP) address of the main user device  616   a . For example, the entry of the user account may also comprise a cellular phone number related to the main user device. In addition to the main device  616   a , each one of the user accounts may be associated with one alternative user device  616   b . Each one of the user accounts may be also associated with one second alternative user device  616   c . Accordingly, the entry of the user account may comprise an identification of an alternative user device and, in some embodiments, an identification of a second alternative user device  616   c.    
     To perform a transaction, a user swipes the payment card  605  at the merchant terminal  612 . In other words, the transaction is executed between a payment card  605  and an associated merchant terminal  612 . Such transaction may be executed when a user buys an item at an entity (such as, for example, a boutique) and then pays for that item with the payment card  605 . There may be many merchant terminals, and many transactions may be executed during a given accumulation period. As illustrated in  FIG. 12A , during the given accumulation period, transactions 1 . . . Nt may be performed, where Nt is an integer. 
     At step  1304  of the method, when performing the transaction, the associated merchant terminal  612  senses the payment card  605  to receive a card identification (ID). Sensing the payment card  605  may be during the scanning the payment card  605 . The merchant terminal  612  then generates a unique time stamp based on a specific time of the execution of the transaction. The merchant terminal  612  thus collects the transaction data  1212  during each transaction and then transmits the transaction data  1212  to the refund server  610 . the transaction data  1212  is then transmitted to the refund processor  1110  of the refund server  610 . During the given accumulation period, which may be determined by an operator and/or described above, the refund processor  1110  receives the transaction data from various merchant terminals  612 . 
     The transaction data comprises the card ID, the unique time stamp generated by the merchant terminal and representative of a specific time at which the transaction took place, a transaction ID generated by the merchant terminal, and a number representative of the purchase price for the transaction. In some, examples, the card ID may be received during scanning of a code. 
     In an alternative embodiment, for some or all transactions executed during the given accumulation period, the card ID may be collected by the merchant terminal  612  when the user or a merchant enters the card ID in a respective box of the prompt at the merchant terminal  612 . In such embodiments, the merchant terminal  612  may be a computer device and the user may make a purchase on that computer device, and the merchant terminal  612  receives an input of the card ID and generates the time stamp at the moment of receiving the input with the card ID at step  1306 . At step  1308 , the transaction data  1212  is received by the refund server  610 . 
     According to an embodiment, each merchant terminal  612  has a transmitter (not shown) and a receiver (not shown) to collect an information signal when scanning the payment card  605 . The transaction performed within the given accumulation period between the payment card  605  and the merchant terminal  612  (when the user uses the payment card  605  to purchase an item) comprises scanning, by the merchant terminal  612 , the payment card  605  by transmitting a requesting signal towards the payment card  605  and receiving an information signal by the merchant terminal  612 , wherein the information signal received from the payment card  605  during the transaction comprises the card ID. 
     According to a further embodiment, the merchant terminal  612  determines the unique time stamp of the transaction based on the time of receiving of the information signal from the payment card when the payment card  605  is located in proximity of the merchant terminal  612 . 
     According to yet another embodiment, the merchant terminal  612  determines the unique time stamp of the transaction based at the time of clicking or pushing of a submit button in response to a prompt to enter the payment card ID on the merchant terminal  612 . 
     At step  1308 , simultaneously with receiving the transaction data  1212  by the refund server, a portion of the number representative of the purchase price (the purchase price being a part of the transaction data  1212 ) is received and then transmitted to the trust account  1130  to accumulate a balance amount of the trust account  1130 . The portion of the number representative of the purchase price is also referred to herein and schematically illustrated in  FIG. 12A  as a “portion of the purchase price  1213 ”. The portion of the purchase price  1213  is less than the purchase price, as described above. 
     The transaction data is then stored in the transaction database  1115  with other transaction entries at step  1312 . The transaction entries are organized in the transaction database  1115  as sequenced transactions—as described above and as illustrated, for example, in  FIG. 8 . As described above, the sequenced transactions in the transaction database  1115  are ordered based on time. For each transaction executed during the given accumulation period, the transaction data  1212  is thus received and stored in the transaction database  1115 , as illustrated in  FIG. 12A . 
     After the given accumulation period has been expired, at step  1214  ( FIG. 12A ), the refund processor  1110  selects a subset of the sequenced transactions (step  1216 ) in the transaction database  1115 , from all the transactions executed during the given accumulation period. A given refund time is then determined as described above. 
     The refund processor  1110  then, at step  1218 , labels the transactions of the subset of the sequenced transactions  1220  as labeled transactions. Such subset of the sequenced transactions for labeling is selected starting with a first labeled transaction, which is the most cotemporal to the given time based on the unique time stamp of the first labeled transaction. The subset of the sequenced transactions ends with a cut-off labeled transaction, where a sum of each number representative of the value of the transactions, for the labeled transactions between and including the first labeled transaction and at least a portion of the cut-off labeled transaction, is equal to or more than the balance amount. 
     Thus, the refund processor  1110  labels several accounts—also referred to herein as “labeled accounts”—which are stored in the user account database  1120  and which correspond to the subset of the sequenced transactions  1220 . In other words, based on the subset of the sequenced transactions  1220  determined earlier, the refund processor  1110  determines a subset of labeled user accounts  1222  of the user account database  1120 . Each labeled account of the labeled user accounts  1222  corresponds to at least one labeled transaction. A transitional step  1290  in  FIGS. 12A and 12B  illustrates how the flow chart of the method  1200  continues from  FIG. 12A  to  FIG. 12B . 
     Referring to  FIG. 12B , where the step  1218  is illustrated in further details, for each transaction that has a time stamp that is cotemporal with the given refund time, or later than the given refund time, and while the amount in the trust account  1130  is more than 0, the refund server  610  labels the transactions to get labeled transactions, and the corresponding user account as the labeled user account. The label may be added by the refund server  610  to the account database entry corresponding to the labeled transaction. 
     Now referring to  FIG. 11  and  FIG. 12B , after the refund processor  1110  has determined the labeled the user account, the refund processor  1110  generates a corresponding notification script  1142  at step  1240  and transfers, at step  1241  ( FIG. 14A ), the notification script  1142  to the notification server  608  (in some embodiments, via the network  614 ). 
     The notification script  1142  comprises identification of the user account, amount of the refund, the address of the notification server, and the identification of the main user device  616   a . The identification of the main user device  616   a  may comprise at least one of an Internet Protocol (IP) address of the main user device and a cellular phone number related to the main user device. 
     In some embodiments, the notification scripts  1142  for all or several labeled accounts are generated and transmitted to the notification server  608 . The notification server  608  has a notification processor  1162  and a notification computer-readable memory  1164  for instructions to be executed by the notification processor  1162 . The notification script  1142  is a computer script and is configured to be executed by the notification server  608 . In addition to data specified above, the notification script  1142  comprises instructions to communicate and to maintain communication with main user device  616   a , or other user device  616   b ,  616   c.    
     Upon receipt of the notification script  1142 , the notification server  608  executes the notification script  1142  by the notification server  608 , at step  1242 , by sending a prompt to the main user device  616   a  to approve the refund. At step  1344 , in response to receiving the instructions from the main user device  616   a , the instructions comprising an approval of the refund, the notification processor  1162  generates a refund script for crediting the user account, the refund script  1144  comprising the identification of the user account and an amount of refund. 
     The refund script  1144  is then received and executed by the refund processor  1110  at step  1346 . The refund script  1144  is executed based on the instructions in that refund script  1144  to credit the refund to the user account by transferring the funds of the refund from the trust account  1130  to the user account by increasing, by the amount of the refund, the amount of funds available in the user account, and reducing the trust account  1130  by the funds for a next accumulation period. At step  1348 , the execution of the refund script  1144  is confirmed and the new amount of funds available in the user account is forwarded to the refund server  610 . Reference numbers  1391  and  1392  are provided in  FIGS. 13A and 13B  to illustrate continuation between these flow charts. 
     The steps  1218 ,  1240 ,  1242 ,  1344 ,  1346 ,  1348  described above are executed for each labeled transaction of the subset of the sequenced transactions, and therefore for each labeled user account. 
     In some embodiments, the user account, to which the refund is transferred, is the labeled user account, from which the items were paid during the transaction or after the transaction. 
       FIG. 14A  is a flowchart illustrating steps  1240 ,  1241 ,  1242  of the method, in accordance with at least one embodiment of the present disclosure. In some embodiments, when executing the notification script by the notification server  608  by sending, to the main user device  616   a , a prompt to approve the refund further comprises, the notification server  608  generates and sends a notification to the main user device  616   a . Such a notification may also include the amount of the refund to be credited to the user account, along with the prompt to approve the refund. At step  1452 , the notification server  608  monitors, during a notification period, the instructions received from the main user device  616   a  which corresponds to (is associated with) the labeled user account. The notification period may be pre-determined and may be, for example, 30 minutes, one day, or another period. 
     At step  1454 , the main user device  616   a  generates and pushes an acceptance message to the notification server, the acceptance message (instructions) comprising the main user device ID/address previously identified by the user, the address of the notification server, the confirmation of acceptance of the refund 
     At step  1456 , if, before the end of a notification period, the notification server  608  receives instructions from the main user device  616   a , the instructions comprising a user account ID and an approval of the refund, continue to next step. If not, following the step  1501  ( FIG. 15 ), at step  1503 , the notification server  608  generates a primary expiry script to request an alternative user device ID or an address of an alternative user device, the primary expiry script comprising the main device ID (which may include, for example, address) previously identified by the user and the address of the notification server  608 . 
     At step  1505 , the primary expiry script is sent to the refund server  610 . At step  1507 , the primary expiry script is executed at the refund server  610  to determine an alternative user device. At step  1509 , the alternative user device  616   b  is used, instead of the main user device  616   a , for execution of the following steps, such as step  1240  ( FIG. 14A ), for example, to generate another notification script. 
     If the given period has expired for the alternative user device  616   b , the notification server  608  may prepare a secondary expiry script to return the funds to the trust account  1130 , the secondary expiry script comprising the address or computing device ID of the second alternative user device  616   c  and the address of the notification server  608 , previously identified by the user and recorded previously in the user account database  1120 . Then, the secondary expiry script is sent to the refund server  610 . The secondary expiry script is then executed at the refund server  610  to return the funds to the trust account. 
     According to an embodiment, the refund server  610  is further linked for data communication to a quarantine account (not shown), and further wherein the method further comprises, in the absence of the approval of the refund from the alternative user device  616   b ,  616   c  during the other notification period, generating, by the notification server  608 , a secondary expiry script for execution by the refund server to transfer the refund to the quarantine account. 
     According to another embodiment, the method further comprises, after a quarantine period: generating and sending, by the notification server  608 , a quarantine notification to the main user device  616   a , the quarantine notification including the amount of the refund to be credited to the labeled user account; and monitoring during a quarantine notification period, by the notification server  608 , approval of the refund from the main user device  616   a.    
     According to yet another embodiment, in the absence of the approval of the refund from the main user device  616   a  during the quarantine notification period generating, by the notification server  608 , a quarantine expiry script for execution by the refund server  610  to diffuse the refund for alternative uses. The alternative uses include, but are not limited to, using the funds for special occasions as described herein; or adding the funds to the balance of the trust account for diffusion in association with another given accumulation period. 
     Referring now to  FIG. 14B , in some embodiments, at step  1462 , the notification server  608  generates an authentication script to request a login information to the user account. At step  1464 , from the notification server to the user device, transmitting the authentication script to request the login information to the user account. At step  1466 , in response to receiving a notification from the main user device  616   a  that the user clicked on the notification link, a login page is displayed and prompts the user to enter (input) an account login ID and password requested on the main user device  616   a . At step  1468 , the notification server requests, from the main user device  616   a , a passcode. The passcode is captured in response to the user entering the passcode at the main user device  616   a . At step  1470 , the refund server  610  verifies the passcode received from the main user device  616   a . At step  1472 , in response to the user clicking on the refund link, a notification of acceptance of the refund is received from the main user device  616   a.    
     Referring to  FIG. 14C , in some embodiments, the prompt sent by the notification server  608  may also comprises a prompt to identify at least one user-designated account. The instruction received from the main user device  616   a  may also comprise an identification of the at least one user-designated account and the refund script may also comprise the identification of the at least one user-designated account. For example, the user may request to transfer the funds to more than one account and the data regarding these additional user-designated accounts may be transmitted from the main user device  616   a.    
     Still referring to  FIG. 14C , the method comprises, at step  1474 , prompting the user to select whether the refund should be credited to the user account or to another account or to other purchasing accounts (PayPal, Amazon, Cryptocurrencies). If the user selects the user account, at step  1476 , a confirmation is received from the user device that the refund should be credited to the user account (which becomes a “user-designated account”). If the user does not select the user account, at step  1478 , a confirmation is received that the refund should be credited to an account other than the user account, so-called user-designated account. Then, at step  1480 , an identification of the user-designated account (which becomes the “user account” for execution of further steps) is received. 
     While preferred embodiments have been described above and illustrated in the accompanying drawings, it will be evident to those skilled in the art that modifications may be made without departing from the concept and method of this disclosure. Such modifications are considered as possible variants comprised in the concept and method of this disclosure.
