## Title
Prepaid negative balance fee processing and fee diversion

## Abstract

Systems and methods are provided for a prepaid credit card processing system wherein components or entities such as the acquirer, issuer, or prepaid card processing network can dynamically determine, at the time of the transaction, whether a credit card transaction will be allowed—even where the fee associated with the transaction would cause the balance to fall below zero.

## Background
FIELD OF THE INVENTION
This invention relates, in general, to payment cards such as but not limited to prepaid credit cards.
BACKGROUND
Prepaid credit cards, such as payroll and general spend cards, offer a solution to underbanked and nonbanked consumers. For example, prepaid credit cards have been developed to be used by employers as an alternative to direct deposit for unbanked employees. Such cards for example, may be used to pay bills, or use PIN-based technology through one or more point of sale (POS) or ATM networks.
However, there are fees associated with prepaid cards. For example, fees may be charged for transaction events such as withdrawing money from an ATM, ATM balance inquiries, POS purchases or other types of transactional activities.
As recognized by the present inventor, when the prepaid account approaches zero, the fee associated with a transaction event may cause the card balance to drop below zero. In this instance, the transaction would be denied, even if there were sufficient funds to complete the transaction alone.
It is against this background that the various embodiments of the present invention were developed.
SUMMARY
According to one broad aspect of one embodiment, disclosed herein is an apparatus for negative balance processing of a prepaid card. The apparatus may comprise a database for storing a fee criteria associated with the prepaid card and cardholder data associated with the prepaid card; a processing engine that receives transaction data from a transaction event associated with the prepaid card, receives prepaid card data from the database and compares the card data to the transaction data in order to selectively determine whether the transaction is allowed, disallowed, allowed with a partial fee or allowed with the fee diverted to an associated diversion account.
According to another broad aspect of one embodiment, disclosed herein is a method for processing a prepaid card. The method may comprise accessing prepaid card data associated with the prepaid card. The prepaid card data comprises at least a card balance and a fee criteria. The method further comprises receiving transaction data from a transaction event associated with the prepaid card. The prepaid card data may be compared to the transaction data and based on the comparison between the prepaid card data and the transaction data, the criteria from the associated fee criteria may be applied in order to selectively determine whether the transaction is allowed, disallowed, allowed with a partial fee or allowed with the fee diverted.

DETAILED DESCRIPTION
Embodiments presented herein relate to a prepaid credit card processing system wherein components or entities such as the acquirer, issuer, or prepaid card processing network can dynamically determine, at the time of the transaction, whether a credit card transaction will be allowed—even where the fee associated with the transaction would cause the balance to fall below zero.
As used herein, the term “card” includes but is not limited to, for example, bank cards, prepaid, preloaded or prefunded cards, such as general purpose reloadable cards, travel cards, payroll cards, teen or student cards, commercial cards, gift cards, or any other type of preloaded, prefunded or prepaid conventional payment card that a customer can use in lieu of a cash payment, and these terms are used interchangeably herein. The term “transaction” includes but is not limited to bill pay, point-of-service purchase, ATM withdrawal, balance inquiry, or any other purchase type activity through prepaid card usage. The term “cardholder” includes but is not limited to, for example, a cardholder of any type of credit card (as that term is used herein), a customer or account holder, and these terms are used interchangeably herein. The term “acquirer” includes but is not limited to the merchant's payment processor, the merchant's bank or financial institution who acquires transactions from merchants and routes messages, authorizations or clearing drafts between merchants and a prepaid card processing network, and these terms are used interchangeably herein. The term “issuer” includes but is not limited to a bank or other financial institution that issues the prepaid cards. The term “prepaid card processing network” or “processing network” includes but is not limited to an electronic payment system, or any conventional network or system for authorizing or processing electronic payments and/or settling such payments between entities in a prepaid card system.
Generally, an issuer may configure each card or card program with a set of associated fees. For example, the issuer may charge fees for membership, ATM balance inquiry, ATM withdrawal, POS purchase, maintenance fees, and other operational type transactions. In the case of a prepaid card that is approaching a zero balance, even where there are sufficient funds to cover the transaction itself, such as an ATM withdrawal for a designated amount, the fee associated with the service may be sufficient to cause the balance to fall below zero. Traditionally, under these circumstances, the prepaid card processing network would disallow the transaction due to insufficient funds.
Referring to FIG. 1, FIG. 1 illustrates an example of a block diagram for determining whether to authorize a transaction where the fee associated with the transaction is sufficient to cause the card balance to fall below zero. In FIG. 1, the issuer is provided with a processing engine 10 for dynamically and in real-time determining whether a particular card transaction will be allowed, disallowed, allowed with a partial fee, or allowed with the fee portion being diverted.
In FIG. 1, the system 100 may comprise a processing engine 10, a database 20 integrated with or in communication with a fee criteria which may be in the form of a fee database or platform 30. For example, a client configuration form that indicates the issuer's fee schedule for a card program may be executed by the fee platform 30. The fee platform 30 may further be in communication with the processing engine 10 directly or through the database 20. Fee platform 30 may be in communication with or integrated with a prepaid card processing network 40. The processing engine 10 may also be in communication with (or integrated with) prepaid card processing network 40, which receives transaction data 50 for the originating prepaid card transaction event. The processing engine 10 automatically compares the prepaid card data (e.g., stored in database 20) with the transaction data 50 and applies the fee criteria associated with the card according to the result of the comparison between the prepaid card data and the transaction data in order to selectively determine whether and at what extent to authorize the transaction. The process may further be implemented as a process, logic or rules within a computing or electronic device.
One example of a prepaid card that may use negative balance processing is a payroll card. A payroll card is an option for an employer to provide to underbanked or non-banked employees as an alternative, for example, for direct deposit or written paychecks.
In various embodiments, as used herein, the term employer may be used to refer to alternative embodiments. For example, the term employer may be used to generally refer to an entity or person/persons responsible for loading the card. For example, negative balance processing may be similar for prepaid cards established to provide government granted benefits, including but not limited to social security benefits, disability payments, Medicare/Medicaid, and welfare payments. In this instance, the term employer would refer to a government agency.
In further embodiments, the term employer may refer to a person or entity that is responsible for loading the card such as, a parent that loads a spend card for a college student.
In various embodiments, the prepaid card transaction event may be an event that triggers a fee within the fee criteria. For example, a POS transaction, bill pay, ATM inquiry, ATM withdrawal, or other transactional or operational type event. According to the fee criteria designated by the issuer, each event may be associated with a fee.
As illustrated in FIG. 1, the transaction data 50 from the prepaid card transaction event may be communicated to the prepaid card processing network 40. Transaction data 50 may comprise for example, a transaction type, a transaction amount, a card holder name, a card identification that identifies the fee platform 30 associated with the card or card program, a merchant name and/or identifier, and any other associated transactional information. The transaction data 50 may further be communicated to the processing engine 10.
The processing engine 10 may receive or access card holder records stored by the database 20 and compare the data from the database 20 to the prepaid card transaction data 50 in order to determine authorization of the transaction. The database 20 may be implemented using any conventional database technology. The database 20 may comprise one or more fields for card holder data such as for example, name, address, phone number, transaction history, and card/account number. In one example, the database 20 may integrate a fee criteria/platform 30 or communicate with the fee criteria/platform. In this way, the database 20 has access to the fee criteria associated with the card or card program.
In one embodiment, the fee platform 30 is implemented between the issuer and the prepaid card processing network 40 during the initial implementation process and may be configured by the issuer to correspond uniquely to a particular card or card program. The fee platform 30 directs the fee criteria on a fee-by-fee basis for the card. In various embodiments, the issuer may structure the fee platform 30 according to any number of variables. For example, the fee platform 30 may contain one or more fields such as fee types charged for a particular card program, for instance, a membership or initiation fee, maintenance fee, ATM withdrawal fee, etc. In another example, the issuer may determine the triggering event for the fee, for instance, card purchase, card maintenance, ATM withdrawal, ATM inquiry, etc. In another example, within each field the issuer may determine the frequency of fees charged, for instance, fee charged per occurrence, per month, per year, etc. In yet another example, within each field the issuer may determine the range type for a card program, for instance, the issuer may configure multiple fee amounts based on how many times that fee occurs. For example, the first two ATM withdrawals are charged a fee of $1.00. The next three withdrawals are charged a fee of $2.00 and the next three withdrawals are charged a fee of $3.00. Further, each range may further comprise a range reset period, for instance, the card fee structure may be reset daily, weekly, monthly, yearly, etc.
As shown in FIG. 2, in one example, a graphical user interface (GUI) may be used to access a number of fields associated with fee type. For example, fees may be charged for ATM Balance Inquiry (the fee to the card holder for a balance inquiry transaction from an ATM), ATM Withdrawal (the fee to the card holder for a withdrawal transaction from an ATM), Teller Cash Withdrawal (The fee to the card holder for a teller cash transaction from a merchant), and PIN POS purchase (the fee to the card holder for a PIN POS purchase from a merchant) to name a few.
As shown, the fee range may further be subdivided based on number of times per fee type. For example, for the first 1-5 times, the fee may be $1.50 and for each subsequent action related to that fee type the fee may be $2.50.
The fields for various fee criteria may further incorporate instructions for fee payment. For example, in one embodiment, the employer, to incentivize its workers to enroll in a payroll program may elect to pay for at least some of the cardholder fees that are charged by the issuer. For example, the employer may establish one or more diversion accounts associated with one or more cards or card programs. The diversion accounts may be established to pay employer elected cardholder fees; for instance, the employer may pay an initiation fee, and/or two ATM transaction fees.
In one example, the issuer may configure the fee criteria to allow one free ATM transaction per month. The employer may elect to subsidize two additional ATM transactions for that monthly period. In operation, when the employee makes an ATM withdrawal, the ATM fee is triggered according to the criteria designated in the fee platform 30. Within the fee platform 30, an additional fee criteria may be associated with the triggered fee. In processing the transaction, the processing engine 10 applies the fee according to the criteria designated in the fee platform 30. For example, for the second or third transaction the fee may be diverted to an employer diversion account associated with the card. In this instance, settlement of the fees occurs between the issuer and the employer.
In another example, a comparison may be performed to check the prepaid card balance received from the database 20 against the transaction amount to ensure that there are adequate funds in the card account to cover the transaction amount and the fee associated with the transaction event. In some cases there are adequate funds in the prepaid card account to cover the transaction amount but not the fee. That is, the fee would cause the prepaid card balance to fall below zero. This is referred to herein as negative balance processing. In various embodiments, the fee criteria may be configured with at least four options for negative balance processing. For example, as shown in option 62 of FIG. 1, an employer may designate an employer account to receive the fee portion of a transaction for one or more fee types where the fee would cause the card balance to fall below zero. In another option 64, the fee platform 30 may be configured to disallow a transaction for a particular fee type for insufficient funds. In another option 68, the fee platform 30 may be configured to allow a transaction and dynamically change the fee for the specified fee type to the remaining balance after the transaction amount (i.e., charge a partial fee). In another option 66, the fee platform 30 may be configured to allow the transaction and allow the account balance to fall below zero by the partial or full fee amount.
FIG. 3, illustrates an example of logical operations for providing employer diversionary accounts. In one embodiment, the employer may elect to pay for certain fees related to negative balance processing. At a first operation 310, the issuer designates a fee criteria for a card or card program. In one example, the fee criteria may comprise fee amounts per fee type. The fee amounts may comprise further criteria on a fee type by fee type basis, for example, frequency charged for each fee type, ranges within each fee type or designation. At a second operation 320, an employer may elect within each fee type whether to pay fees on behalf of an employee. For example, the employer may elect to pay ATM withdrawal fees in a negative balance situation. In a further embodiment, the employer may elect to pay only certain fee types (for instance, fees for ATM withdrawal but not fees for balance inquiry), where the trigger for payment is predefined for example, the trigger may be a negative balance situation. In a third operation 330, to accommodate payment of fee types, the employer may link one or more diversion accounts associated to a card or card program. In a fourth operation 340, the issuer configures the fee criteria according to the employer fee payment elections, including for example, election of fee types, fee trigger events, and diversion of certain fee types according to preset triggers.
As further shown in FIG. 1, in alternate embodiments, the issuer may configure the fee platform 30 with respect to negative balance processing in cases where a diversionary account does not apply. In various embodiments, the issuer can determine on a fee-by-fee basis how to proceed with the transaction. For example, for each fee type (i.e., ATM withdrawal, ATM balance inquiry, POS sale, etc.) the issuer may configure the fee platform 30 to direct the processing engine 10 to selectively determine whether the transaction proceeds by one of: allow the transaction and allow the card balance to fall below zero (66); require the full fee and disallow the transaction due to insufficient funds (64); or allow the transaction and dynamically change the fee, i.e., allow a partial fee (68).
Referring to FIG. 1, the fees may be triggered by a transaction event and charged according to the criteria in the fee platform 30. According to the fee platform 30, the fees may be assessed to the card holder account, the employer account, and the issuer (for example, a promotional fee).
FIG. 4 illustrates an example of logical operations for negative balance processing. In a first operation 410, the card holder initiates a prepaid card transaction event. In one example, the transaction event may be a POS purchase for a transaction amount. In a second operation 420, the transaction data (for example, the transaction amount and card holder data) may be communicated to the prepaid card processing network. At a third operation 430, the processing network communicates the transaction data to the processing engine. At a fourth operation 440, the processing engine retrieves the fee triggered by the transaction event and any further fee criteria from the database and/or fee platform. The processing engine may further receive a card balance from the database. At a fifth operation 450, the processing engine compares the transaction data to the card data received from the database to determine whether negative processing criteria apply. In a sixth operation 460, the processing engine applies the fee criteria to determine whether the transaction is allowed and the account balance falls below zero, allowed for partial fee, allowed with the fee diverted or declined.
FIG. 5 illustrates an example of logical operations for negative balance processing. At operation 510, the transaction processing network receives the transaction data for a card and forwards the data to the processing engine. At operation 520, the processing engine communicates with the database and retrieves account data associated with the card. At operation 530, the processing engine receives the card data. The card data comprises the fee triggered by the transaction type and may further comprise criteria associated with the transaction type including negative balance processing criteria triggered by a negative balance event. The processing engine compares the card balance to the transaction amount after application of the fee. At operation 540, if triggered, the processing engine applies a negative balance processing criteria associated with the card. At operation 550, with respect to the transaction, the criteria may selectively determine allowance of the transaction with the fee diverted to an employer account; allowance of the transaction with partial fee due, for instance, the remaining balance on the account; allowance of the transaction with the account balance allowed to fall below zero; and disallowance of the transaction with full fee due. For each criteria, the processing network may further provide a report with respect to revenue lost/gained for each fee type and each fee configuration.
For example, applying the fee criteria, in a first option for each fee type, the issuer may configure the fee criteria to allow the transaction with the fee due diverted to an associated account. For example, for a transaction event of a $40 ATM withdrawal, the issuer configured the fee as $1.00 and further configured within the criteria that if the fee would cause the card balance to fall below zero, the fee should be diverted to a designated employer account. Accordingly, for a card having a balance of $40.50, because the $1.00 fee would cause the card balance to fall below zero, only the transaction amount of $40 would impact the card holder account and the $1.00 fee would be diverted to the employer account.
In a second option, for each fee type the issuer may configure the fee criteria to allow the transaction and allow the account balance to fall below zero. In this example, for a card balance of $40.50 and an ATM withdrawal event for $40 with a fee required of $1.00, the transaction and the fee would be applied to the account thereby allowing the account to fall below zero by $0.50. In a further embodiment, the prepaid card processing network may provide the issuer with a fee revenue report with respect to negative balance processing.
In a third option, for each fee type the issuer may configure the fee criteria to allow the transaction and dynamically adjust the fee to yield an account balance of zero. For example, for a transaction event of a $40 ATM withdrawal, the issuer may configure the fee for the event as $1.00 and further configure within the criteria that if the fee would cause the card balance to fall below zero, the fee may be dynamically adjusted to equal the remaining balance on the card. In this example, because the full fee would cause the balance to fall below zero, the fee may be adjusted to $0.50 thereby bringing the account balance to zero and allowing the issuer to collect at least a partial fee for the transaction event.
In an alternate embodiment, the fee may be configured to dynamically change the fee required to a predetermined partial fee amount. If there are insufficient funds in the card holder account for the preset partial fee, the fee may default to an alternate option for negative balance processing. For example, disallow the transaction or divert the fee as configured by the issuer.
In a further embodiment, for each fee type the issuer may configure the fee criteria to allow dynamic configuration of only certain fee types. For example, the issuer may allow dynamic adjustment of an ATM withdrawal fee but not an ATM inquiry fee. As one example, a card has a balance of $40.95. The transaction is an ATM withdrawal for $40 and the fee for the withdrawal should be $1.00. The cardholder makes an ATM withdrawal of $40. According to the fee criteria, the ATM fee associated with the transaction is $1.00. In the instance that the fee criteria is configured to allow dynamic adjustment of the ATM withdrawal fee, the prepaid card processing network may dynamically change the fee to $0.95 and allow the transaction thereby bringing the card balance to $0. However, subsequent to the transaction, if the card holder then places a request for a balance inquiry and the fee criteria is configured to disallow diversion or adjustment of fees for balance inquiries, because the balance is zero, the transaction would not be allowed.
In a fourth option, the fee criteria may be configured to require the full fee of $1.00. For example, for a cardholder balance of $40.95, a request for an ATM withdrawal of $40.00 associated with a fee for $1.00, would be denied due to insufficient funds. That is, because the transaction and fee exceeds the balance on the card, and the issuer configured the fee criteria to require the full fee amount for that fee type, the transaction would not be allowed. In a further embodiment, the prepaid card processing network may generate a fee income lost report to notify the issuer of lost revenue because the transaction was denied.
In one embodiment, as shown in FIG. 6, the fee detail may be accessed through a fee detail GUI. In various fields, card user information may be presented such as the program information associated with a card, the Issuer, the location, the fee table type, the fee information including fee ID, fee name and card type. Fields may further be provided to view triggering events, frequency, range type, reset period, fee starting point, fee applied, charge to (funding source). In another embodiment, the fields may be used to define fee ranges. For example, the first 1 to 5 triggering events are $2.00, the subsequent 6-10 triggering events are $4.00, and so on.
In a further embodiment, fields may be provided to define fee diversion including for example, frequency, reset period, and count to be diverted. In further embodiments, the negative balance option may be selected including for example, not applicable for this fee type, allow negative balance, disallow negative balance partial fee allowed, disallow negative balance full fee required. For instance, if an Issuer allows a negative balance, the requested activity may be allowed to take place without regard to the general ledger balance. As a result, the full fee is applied and the fee assessment operations may cause the general balance to become negative.
In another example, the Issuer elects to disallow a negative balance but allow a partial fee. In this instance, although the requested activity is allowed, the ledger balance is not allowed to fall below zero due to the fee assessment operations. As a consequence, only a portion or none of the fee may be assessed.
In a further example, the Issuer requires a full fee to be assessed. In this instance, depending on the definitions provided by the Issuer, the Authorization and Services transactions may be denied and other fee types may bypass charging the fee.
Through the authorization of certain transaction events in a negative balance processing situation, the issuer may benefit from significantly increased proceeds due to collection of partial fees, diverted fees and by allowing card balances to fall below the zero balance threshold. In various embodiments, the prepaid card processing network may further provide fee reports for each authorization type in order to enable the issuer to select the most profitable course of action for various transaction events and card balance situations.
