## Title
Communication device including multi-part alias identifier

## Abstract

Methods and systems are disclosed for allowing financial transactions to be conducted using consumer devices. In some embodiments, the consumer device is a mobile communication device, such as a mobile phone. A payer initiates a transaction by sending a payment request message from a mobile phone which specifies the payee and amount to be paid. Payees are identified by unique aliases, which are maintained in a database. The aliases, in turn, are comprised of multiple parts. Each part of the alias may identify a relevant aspect of the transaction. For example, one part of the alias may identify the payee and another part of the alias may identify the financial institution of the account of the payee. Methods for assembling the enrollment and alias database are included.

This application claims priority to U.S. Patent Application No. 61/052,028 entitled “Payment System With Push and Pull Requests and Responses” filed on May 9, 2008.


BACKGROUND
The use of consumer devices to conduct financial transactions is growing in popularity. Consumer devices ranging from personal computers to cellular phones can all be used to conduct financial transactions. Various means of using consumer devices to conduct financial transactions have been tried. One of the most common means for conducting a financial transaction involves sending a payment to a payee using the payee's cellular phone number as an identifier. This approach, however, gives rise to several problems. First, the payee must have a cellular phone which is capable of receiving the payments. Second, the payer must know the payee's phone number. As cellular phone numbers tend to change frequently, a payer must make certain that the phone number being used is current. The payer otherwise runs the risk of sending a payment to an unintended third party, who has been assigned the intended payee's old phone number. In some cases, the payor and payee may not wish to reveal personal information such as their cellular phone numbers or financial account information to each other. Additionally, the payor and payee may wish for the payment to be sent to or sent from a specific financial account associated with one of the parties to the transaction.
Alias identifiers have been developed to address some of these problems. Alias identifiers are generally described in U.S. patent application Ser. No. 11/767,033, which is hereby incorporated by reference in its entirety for all purposes.
As alias identifiers have become more widely used, some problems with alias identifiers have arisen. In some embodiments, a payment processing network, or other centralized entity, controls the database and server computers used to create alias identifiers and used to resolve alias identifiers during payment transactions. One consequence of this centrally controlled alias identifier system is that financial institutions that manage accounts do not have very much control over the aliases associated with their accounts. Financial institutions have expressed the need to have more control over their aliases and a greater ability to track the aliases associated with their accounts. In the context of a centrally managed system, giving many different financial institutions control over their aliases while at the same time maintaining the integrity of the system can be problematic and needs to be implemented in a fashion that does not cause problems in the system's functionality. An additional problem that has developed for consumers is that if a first consumer creates an alias for their identity, a second consumer cannot create the same alias for their identity even if the second consumer does not have any accounts with the financial institutions of the first consumer.
Embodiments of the invention address these and other problems.
BRIEF SUMMARY
Embodiments of the invention are directed to devices and systems for allowing payments to be made using consumer devices. In some embodiments, the consumer devices used are portable consumer devices, such as mobile phones.
One embodiment is directed towards a consumer device comprising a processor and a network interface configured to send messages from the consumer device. The consumer device also contains a computer readable medium comprising code executable by the processor. The code executable by the processor comprises code for sending a payment request message to a server computer via the network interface. The payment request message includes a request to pay a payee a predetermined amount of money and contains an alias identifier. The alias identifier comprises a first part and a second part, and at least the second part of the alias identifier identifies a financial institution of a destination account for the predetermined amount of money. The server computer that receives the payment request message is configured to facilitate the transfer of the predetermined amount of money to the destination account.
Other embodiments of the invention are directed to systems, computer readable media, and methods adapted to implement the above device.
These and other embodiments of the invention are described in further detail below.

DETAILED DESCRIPTION
Embodiments of the invention are directed to making person-to-person (P2P) and/or person-to-business (P2B) payments, using consumer devices and portable consumer devices. In embodiments of the invention, a payer may send a payment request message to a payment processing network. The payment request message identifies the desired payee using an alias, which is uniquely associated with the payee.
The alias may have multiple parts, with each part of the alias identifying a relevant aspect of the payment. According to various embodiments, one of the parts of the alias may identify the financial institution of the payer account or the financial institution of the payee account. For example, an alias such as “beachbum.secondbank” contains two parts. The first part of the alias, “beachbum,” identifies the potential payer or payee. The second part of the alias, “secondbank,” identifies the financial institution of the account. In some embodiments, “secondbank” is also an entity that manages the alias “beachbum” on databases and servers controlled by an issuer such as BankTwo. BankTwo's alias records may then be periodically synchronized with alias databases and server computers managed by a central entity, such as a payment processing network. The alias “beachbum.secondbank” may refer to a different payee or payer from the payee or payer associated with the alias “beachbum.firstbank.” The alias “beachbum.secondbank” links to an account at BankTwo that is separate from the account linked to by alias “beachbum.firstbank” at BankOne.
One skilled in the art will recognize that there are many potential ways to separate the various parts of an alias. For example, the above examples use the character “.” to delimit the various parts of an alias. Alternative deliminiting characters may also be used. Additionally, other well-known means for separating segments of a data string may also be used.
Multi-part alias identifiers yield several advantages over prior alias identifiers. For example, multi-part alias identifiers allow financial institutions to more easily search for and track alias identifiers associated with their accounts. According to some embodiments, a financial institution may manage the alias identifiers associated with their accounts on server computers controlled by the financial institution. Another advantage of multi-part alias identifiers is that different consumers who have accounts with different financial institutions can have partially overlapping aliases. For example, “beachbum.firstbank” may refer to a different consumer than “beachbum.secondbank” because the financial institutions behind the account are different.
When a payment request message with an alias is sent from a consumer device to a payment processing network, the payment processing network may then determine the information behind the alias using an enrollment and alias database. According to some embodiments, the alias database accessed may depend on information contained in the alias itself. For example, the alias “beachbum.firstbank” may cause the payment processing network to access an alias database associated with BankOne, while the alias “beachbum.secondbank” may cause the payment processing network to access an alias associated with an alias database associated with BankTwo. The database accessed may be controlled by the payment processing network, or the database accessed may be external to the payment processing network. For example, an accessed database may be controlled by a financial institution.
After determining the information associated with the alias, the payment processing network may then forward the payment request message to a payer institution. The payer institution may be a payer bank and the payer may have a payer account associated with it. The payer institution may thereafter analyze the payment request message and may authorize or not authorize the transaction depending on whether the payer has sufficient credit and/or funds in the payer's account. If the payment request is approved by the payer institution, the payer institution may thereafter transfer funds from the payer's account at the payer institution to a payee account at a payee institution.
The payment request message may be sent from the payer's consumer device in any suitable manner. In one example, a payer may send the payment request message to the payment processing network via a web page accessed by the phone. A similar web page accessed by a browser running on a personal computer may also be used to send a payment request message. In another example, the payer may send the payment request message to the payment processing network using an SMS message (i.e., a text message). In yet another example, the payer may send the payment request message to the payment processing network using a software application on the phone.
The payment transactions according to embodiments of the invention may take place in any suitable context. For example, suitable payment transactions may involve purchases of goods and services from merchants or individuals in a person to business or person to person context: However, in some embodiments of the invention, a payer may make payments and the payments can be made without any return consideration (e.g., a good or service purchased). For example, a payment may be a gift to the payee or repayment of a debt to the payee where the payer does not receive immediate consideration for the payment.
I. Systems
FIG. 1 shows a system that can be used in an embodiment of the invention. Embodiments of the invention may use some or all of the components shown in FIG. 1.
The illustrated system includes a payer 302 and a first consumer device 304 associated with the payer 302. The payer 302 has a payer account 316 at a payer institution 314. Similarly, the system includes a payee 306 and a second consumer device 308 associated with the payee 306. The payee 306 has a payee account 320 at a payee institution 315. According to some embodiments, the first consumer device 304 or the second consumer device 308 or both may be portable consumer devices, such as mobile phones. According to some embodiments, the first consumer device 304 or the second consumer device 308 may be typical personal computers.
In this example, the payer institution 314 and payee institution 315 are shown as separate entities. The payer 302 and payee 306 could use the same financial institution in other embodiments of the invention.
The payer institution 314 and payee institution 315 are typically banks that manage financial accounts for individuals or businesses. However, they could also be business entities such as retail stores.
The payer 302 and payee 306 may be individuals, or organizations such as businesses that are capable of entering into financial transactions (e.g., payment transactions).
The payment processing network 310 may include data processing subsystems, networks, and operations used to support and deliver authorization services, exception file services, and clearing and settlement services. An exemplary payment processing network may include VisaNetTM. Payment processing networks such as VisaNetTM are able to process credit card transactions, debit card transactions, and other types of financial transactions. VisaNetTM, in particular, includes a VIP system (Visa Integrated Payments system) which processes authorization requests and a Base II system which performs clearing and settlement services.
The payment processing network 310 may include a payment server computer 312. A “server computer” is typically a powerful computer or cluster of computers. For example, a server computer can be a large mainframe, a minicomputer cluster, or a group of servers functioning as a unit. In one example, a server computer may be a database server coupled to a web server. The server computer 312 may form part of any suitable wired or wireless network, including the Internet.
A gateway 332 may be operatively coupled to the payment processing network 310 and may allow the first and second consumer devices 304, 306 to communicate with the payment processing network 310. The gateway 332 may be embodied by any suitable combination of hardware and/or software known to those of ordinary skill in the art.
The system may also comprise a payer client computer 330(a) as well as a payee client computer 330(b). They can be in communication with an enrollment server computer 326 operating a host site 324 (e.g., a Web site), via a communication medium 328. The communication medium 328 may comprise any suitable combination of wired and/or wireless networks including the Internet. The enrollment server computer 326 may store aliases in an enrollment and alias database 322. The payment processing network 310 can subsequently identify the payee 302 and payer 306 using the information stored in the enrollment and alias database 322.
In some embodiments, the enrollment server 326 and host site 324 may be controlled by an organization that operates the payment processing network 310. In other embodiments, financial institutions, such as payee institution 315 and payer institution 314 may host their own enrollment servers and host sites that are used to create aliases for their consumers. In these embodiments, the financial institution's hosted enrollment server and host site allows financial institutions to more closely track and control the aliases created for their accounts. For example, financial institutions may maintain databases of alias accounts separate from Enrollment and Alias Database 322. Alias information created by the financial institution's hosted enrollment server and host site can then be synchronized with the Enrollment and Alias Database 322, either periodically or on a real-time basis, so that the aliases are available for use by consumers. Aliases that are synchronized between financial institutions and the Enrollment and Alias Database 322 may be multipart aliases with at least one part of the multipart alias identifying the financial institution of the consumer's account.
Payers and payees may also create aliases for other pieces of information that might be used in a payment request message. For example, a payee may assign various aliases for a variety of financial accounts held by the payee. The payee can then instruct a payer to send funds to the payee to one of the payee's accounts using the created account alias. The payer can then include the account alias in the payment request message sent to the payment processing network, and the payment processing network can attempt to send funds from the payer to the financial account of the payee as indicated by the payee account alias. In other embodiments, there can be a separate enrollment database and a separate alias database. In some embodiments, the alias database stores aliases that identify the payer, payee, financial accounts, and other information. In some embodiments, different types of aliases are stored in different databases. In some embodiments, the first and second consumer devices may be the same as the payer client computer 330(a) and the payee client computer 330(b).
Additional details on the components, subsystems, and devices represented in the embodiment illustrated in FIG. 1 are given in more detail later in this disclosure.
II. Enrollment Methods
In embodiments of the invention, payers and payees may first enroll in the system. The payee and the payer may enroll in any suitable manner. For example, referring to FIG. 1, the payee and the payer may enroll in the system via the host site 324 using the client computers 330(a), 330(b). Enrollment information such as name, account number, etc. may be stored by the server computer 326 in the enrollment and alias database 322. This information can be used in subsequent payment processes to identify the payer 302 or the payee 306.
In some cases, a financial institution such as the payee institution 315 or the payer institution 314 may “push” pre-enrollment data to the enrollment and alias database 322. The payer institution 314, for example, may validate the payer 302 ahead of time. The payer institution 314 may do this ahead of time, because it knows the payer 302 and the payer's credit history and account balance information. After the payer 302 is enrolled in the system, the payer 302 may set up an appropriate alias or part of the alias to use the system. According to some embodiments, the alias set up the payer may constitute one part (e.g., a personal alias) of a multi-part alias while information identifying the financial institution (e.g., an issuer alias) may make up another part of a multi-part alias. In other embodiments, the payer may set up only one part of the alias (e.g., the personal alias) while the other part of the alias (e.g., the issuer alias) is set up by another entity (e.g., an issuer). The same may be true for the payee 306. Thus, in some embodiments, the payer 302 need not do anything to enroll and need only set up one or more parts of her payment alias.
In some embodiments, a financial institution such as the payee institution 315 or the payer institution 314 may push full enrollment data to the enrollment and alias database 322. An institution, such as a financial institution, may do this on a periodic basis or in real-time. The payer institution 314, for example, may allow the payer 302 to create an alias or part of the alias for their account on server computers and databases separate from the enrollment and alias database 322, the enrollment server computer 326, or the host site 324 represented in FIG. 1. The alias information created by the payee institution 315 or the payer institution 314 can then be pushed to the enrollment and alias database 322 so that the alias information is available to process payment request messages. The aliases pushed to the enrollment and alias database 322 may automatically be associated with the appropriate financial institution so that alias collisions between financial institutions cannot occur. For example, the aliases or parts of aliases pushed to the enrollment and alias database 322 may be useable as a multi-part alias such as “beachbum.secondbank.” Embodiments that allow financial institutions to create aliases give these institutions greater control on the alias creation process. Each institution can give their creation process a unique look and feel, and each institution can also easily apply any relevant rules they wish to use to control how aliases are created and how they are associated with accounts.
Referring to FIG. 2, Jane registers personal information 502 including her name, mobile telephone number, a credit card account number (CC1), and a personal alias, which may be a first part of the alias to be formed. In this example, the account number associated with credit card 1 (CC1) is associated with the financial institution “BankOne.” John may similarly register his personal information 504 in a similar manner. In this example, Jane creates the personal alias part “worldtraveler,” while John creates the personal alias part “beachbum.” These alias parts may have been created or selected by the user using the enrollment server computer 326, or the host site 324, or they may have been created by systems managed by a financial institution and then pushed to the enrollment and alias database 322.
In this example, the aliases created by Jane and John have different issuers (e.g., BankOne, and BankTwo). In FIG. 2, Jane and John have each created their own issuer alias. Jane has created the issuer alias “firstbank” for issuer “BankOne,” and John has created the issuer alias “secondbank” for issuer “BankTwo.” In some embodiments, the payer and the payee may have to select from a predefined list of possible issuer aliases so that the list of possible issuer aliases is confined.
In embodiments of the invention, a number of alias parts may be used in addition to an issuer alias and a personal alias. Alias parts may include payment processing organization alias parts for the payment processing organization that operates the payment processing network An example of a service provider alias may be “myvisa” for a payment processing organization such as Visa.
Referring to FIGS. 1 and 3, in the first step 202, a payee 306 requests assignment of an alias or a part of an alias. In some embodiments, the payee 306 may specify a particular alias part. However, in other embodiments, a payment processing organization may assign an alias part to the payee 306. To register an alias, the payee 306 may use the client computer 330(b) to contact the host site 324 on the server computer 326. The host site 324 may comprise a wizard or other mechanism to allow the payer 302 and the payee 306 to enter information. In some embodiments, payees and payers may enter information into a host site managed by a financial institution and the financial institution can then synchronize the information they receive with the enrollment and alias database 322.
In the next step 204, the server computer 326 checks the enrollment and alias database 322 to see if the requested alias (or alias part) is already being used by another payee or payer. If the requested alias already exists, then the payee 306 may be asked to provide another alias (step 212). Alternatively or additionally, the requested alias may only be rejected if the alias already exists with the financial institution of one of the accounts held by the payee 306. In some embodiments, financial institutions may have specific rules for accepting or rejecting aliases that will be associated with the financial institution. For example, some aliases may create an objectionable multi-part alias when combined with some financial institution identifier but not with other financial institution identifiers. Financial institutions can set up rules specific to their needs to help manage the aliases that are associated with financial institutions. In some embodiments, an alias may be rejected as already existing only if the aliases are associated with accounts held by the same financial institution.
If the alias (or part thereof) has not been previously registered, then the server computer 326 may register the requested alias for the payee 208. This information may be stored in the enrollment and alias database 322. Once the alias has been registered for the payee 306, the payment processing organization may begin allowing the payee to receive payments made using the alias (step 210). The alias may comprise a first part that corresponds to a personal alias and a second part that corresponds to an issuer alias. In the enrollment and alias database 322, the first part of the alias may be mapped to the payee's (or payor's) account number (which is in turn linked to the payee's name and address. In some embodiments, information from the enrollment and alias database 322 may then be forwarded to the appropriate financial institution so that the financial institution is aware of the created alias and can better track the aliases associated with accounts managed by the financial institution.
This method and other related embodiments of the invention allow for efficient cross-institution payments to be made, by uniquely identifying an individual, business, financial institution, etc., via an alias. The aliases may be associated with many accounts or services operated by an individual or entity, if desired. In some embodiments, the various aliases can be registered for a fee, and consumers may be charged a registration and renewal fee for using certain aliases. Other embodiments may provide the enrollment and alias database as a free service, or charge only certain classes of entities (e.g. charge only payees, or for-profit corporations).
III. Payment Methods
FIG. 4 shows a flowchart illustrating a payment method according to an embodiment of the invention. In the first step 102 the payer 302 decides to pay the payee 306 using the first consumer device 304. The first consumer device 304 may be a phone operated by the payer 302.
A payer 302 then uses the first consumer device 304 and sends a payment request message to the payment processing network 310 and the payment processing network 310 receives the payment request message (step 104). The payment request message comprises at least a payment amount and an alias. The alias may further comprise more than one part, such as personal alias and an issuer alias.
As noted above, the payment request message may take a variety of different forms. For example, the payment request message could be in the form of an SMS message. The request could also come in the form of an email, or a voice interaction with an IVR unit. The request could also be made via a software application on the phone, which sends one or more network packets containing the request data.
In the next step 106, using the enrollment and alias database 322, the server computer 312 in the payment processing network 310 analyzes the payment request message and uses the phone number of the payee (or an alternative payee alias) in the payment request message to identify the payee 306. Other information, such as the payer institution 314 and the payer account 316 may also be identified.
For example, the payment request message for a payment of $10 may comprise information including “pay $10 to beachbum.secondbank.” The first part (e.g., beachbum) of the alias (beachbum.secondbank) can be mapped to a payee's account number (e.g., 6xxxxxxxxxxx6666), while the second part (e.g., secondbank) of the alias can be mapped to the payee's issuer (e.g., BankTwo). The payer 302 may be automatically identified by the server computer in the payment processing network 310, by an appropriate caller ID or other type of identification mechanism. The payer's phone number (e.g., (123) 555-7777) can be identified by the server 312 in the payment processing network 310 and the server 312 can determine the payer's account number including a payer account number (4xxxxxxxxxxx4444) and payer issuer (e.g., BankOne). The payer's information linking the payer's phone number and issuer account number may have been previously stored in the enrollment and alias database 322. As explained earlier, payer information may have been “pushed” into the enrollment and alias database 322 as pre-enrollment data by a financial institution.
To provide security to the system, an optional authentication request message is sent from the payment processing network to the first consumer 304 operated by the payer 108. The authentication request message may be initiated by the payer institution 314 or by a payment processing organization affiliated with the payment processing network 310. It may request entry of a password, or personal information such as an address or social security number to verify the identity of the payer 108. The authentication request message may take a variety of forms, as described for the payment request message 104 above. In preferred embodiments, the authentication request message will be sent to the payer's consumer device 304. It could also be sent to the payer's client computer 330(a).
In the next step 110, the payer 302 provides an authentication token to the payment processing network 310. For example, the payer 302 may enter a PIN (personal identification number) into the first consumer device 304 and may then send the authentication token back to the payment processing network 310, and the payment processing network 310 may or may not forward it to the payer institution 314. Other examples of authentication tokens include passwords, birthdates, and other personal information associated with the payer 302.
The payment processing network 310 (or the payer institution 314) then verifies the authentication token 112. If the authentication token is invalid, the payment request in the payment request message may be rejected. Alternatively, the payment processing network 310 may re-verify the authentication token (step 120) by sending another authentication request message to the payer 302 via the first consumer device 304.
If the payer 302 and/or the first consumer device 304 are authenticated and after the real payer 302 and the payee 306 are determined, the payment processing network 310 may send the payment request message to the payer institution 314 for approval. The payment request message may be re-formatted to remove various aliases and may include the real information. For example, the server computer 312 in the payment processing network 310 may analyze the message “pay $10 to beachbum.secondbank” from phone number (123) 555-7777 is a request from Jane Doe to pay John Doe $10 from credit card account no. 4xxxxxxxxxxx4444 to credit card account number 6xxxxxxxxxxx6666. An appropriate payment message is then sent to the payer institution 314. The payer institution 314 may then approve of the payment request if there are sufficient funds and/or credit in the payer account 316 or disapprove it if there are insufficient funds or credit. If the payment request is approved, at some point in time (e.g., immediately or at the end of the day if clearing and settling need to take place), actual funds may be transferred from the payer account 316 to the payee account 320 via the payment processing network 310.
Once the funds have been transferred from the payer account 316 to the payee account 320, a payment notification message may sent to the consumer device 308 and/or the client computer 330(b) operated by the payee 118 after the payment request in the payment request message has been approved by the payer institution 314.
In a specific example, a payer 302 such as Jane and a payee 306 such as John register on the host site 324 run on a remote server computer 326 using their client computers 330(a), 330(b).
After registering, a payment processing organization may provide both John and Jane with a phone number for the service that will facilitate further payment processing. In other embodiments, the payment processing organization may provide John and Jane with a service alias instead of or in addition to the service phone number. For example, instead of providing John and Jane with the service phone number 555-555-5555, the payment processing organization may provide the service alias “myvisa” to John and Jane. The service alias may be referred to as a “short-code” in some cases, and may include a string of characters of variable length.
In an exemplary transaction, Jane may be a payer 302 and wants to pay $15.00 to a payee 306 named John. Payer Jane 302 initiates a payment to John by entering the payment request message “myvisa pay beachbum.secondbank $15.00” into her consumer device 304, and sending the message via SMS to the server computer 312 in the payment processing network 310 via the mobile gateway 332. The alias “beachbum” is used instead of John's phone number. The service alias “myvisa” is used instead of the phone number of the service. The financial institution alias ““secondbank” identifies the financial institution of the account owned by John where the payment will be deposited.
In some embodiments, Jane may also use a portable consumer device alias such as “CC2” (not shown) to indicate the particular credit card that Jane wants to use to pay John. For example, payee Jane 302 may enter the payment request message “myvisa pay beachbum.secondbank $15.00 CC2” into her consumer device 304 to indicate that a second credit card owned by Jane (not illustrated in FIG. 2) and issued by BankOne (or another issuer) is to be used to make the intended payment. Jane may alternatively or additionally designate a default credit card account number.
After entering the payment request message “myvisa pay beachbum. secondbank $15.00 CC2” into her consumer device 304, the payment request message is sent from her consumer device 304 to the payment processing network 310 (e.g., as described above), and then (in this example) to an financial institution of the credit card (or other portable consumer device). In this example, the financial institution of the credit card may be the payer institution 314.
The payment processing network 310 may receive the payment request message and may then optionally respond by sending an authentication request message to the payer 302. In this example, an authentication request message is sent in the form of a call from an interactive voice response unit (IVR) at a telecom server or the like, which asks payer Jane 302 to enter her mobile PIN (personal identification number) 510. After payer Jane 302 enters the correct PIN into her consumer device 304, the payer institution 314 and/or the server computer 312 in the payment processing network 310 can then attempt to resolve the alias used by payer Jane 302 to determine where the payment request message needs to be sent in order to process the payment. For example, the payer institution 314 and/or the server computer 312 in the payment processing network 310 may access the enrollment and alias database 322 to lookup the alias “beachbum.secondbank.”
Next, the payer institution 314 and/or the server computer 312 in the payment processing network 310 can then analyze the payment request message and reformat it so that it is sent to the payer institution 314 for approval or decline. If the payment request is approved, appropriate funds may be transferred to the payee account 320 at the payee institution 315. For example, payee John's portable consumer device account (e.g., credit card account) at John's bank (e.g., the payee institution, i.e., BankTwo, 315) can be credited with the payment amount. Payer Jane's account 316 can be subsequently debited for the payment amount.
In some embodiments, a payment notification message in the form of an SMS, e-mail, or some other type of message may be sent to the payee's consumer device 308, informing the payee John 306 that a payment from the payee John 302 has been made. In one embodiment, the payment notification message may be sent to payee John's consumer device 308. The payment notification message could be sent to the client computer 330(b) operated by the payee John 306. A payment notification message could also be sent to the payer Jane 302 on Jane's consumer device 304 or Jane's client computer 330(a).
According to some embodiments, the payment notification message may include a payment confirmation code. For example, the payment confirmation code may be a number such as “123456789.” Either the payer 302 or payee 306 can then enter this number into their consumer device or client computer to receive more information on the payment. For example, Jane 302 could enter the received payment confirmation code into a web site configured to accept such codes. The web site would then return a page to Jane 302 informing Jane that “You made a payment of $15.00 to beachbum.secondbank on 1-1-09.” Similarly, John could use the same code to receive a similar message. One skilled in the art will recognize that the code could also be used in an SMS message or any other appropriate communication message to achieve similar functionality. In some embodiments, this confirmation code could also be used by the financial institution of either Jane's or John's account to retrieve information about the transaction.
Embodiments of the invention have a number of advantages. First, the use of an alias allows for a transaction to be completed while keeping the personal information of the transacting parties confidential. This is useful because, for example, a payer may not want to disclose his or her phone number to a payee, or vice versa. Second, the alias allows for payments to be made even if a payee's telephone number or financial account changes. A payer may thus store a list of aliases for payees with whom the payer frequently does business, and may initiate repeated payments without having to verify that the payee's telephone number is the same. Third, aliases tend to be much easier to remember than either phone numbers or financial account numbers. Consequently, embodiments of the invention will be easier to use than other methods. Fourth, embodiments of the invention allow for many accounts to be accessed from a single mobile phone, eliminating the need to carry a large number of portable consumer devices. Fifth, multi-part aliases allow financial institutions to better track aliases associated with their accounts. For example, an financial institution may use the alias database to easily identify their consumers with aliases and then the financial institution can analyze the use of the aliases, payment requests, or any other relevant pieces of information. Sixth, a multi-part alias allows multiple consumers to potentially share the same alias so long as the aliases are associated with different financial institutions. This allows consumer to have greater flexibility in their aliases choices and leads to greater consumer satisfaction.

The interconnection via system bus 775 allows the central processor 773 to communicate with each subsystem and to control the execution of instructions from system memory 772 or the fixed disk 779, as well as the exchange of information between subsystems. The system memory 772 and/or the fixed disk 779 may embody a computer readable medium.
FIG. 6 shows a block diagram of some components of the first consumer device 304 in the form of a portable consumer device. In some embodiments, the first consumer device may be a portable consumer device, such as a mobile phone. Some or all of the components in the first consumer device 304 may also be present in the second consumer device 308 (illustrated in FIG. 1).
The portable consumer device 32 may comprise a computer readable medium 32(b) and a body 32(h) as shown in FIG. 6. The computer readable medium 32(b) may be present within body 32(h), or may be detachable from it. The body 32(h) may be in the form a plastic substrate, housing, or other structure. The computer readable medium 32(b) may be a memory that stores data and may be in any suitable form including a magnetic stripe, a memory chip, etc.
The computer readable medium 32(b) may comprise code for performing any of the functions described herein. For example, it may comprise code for sending a payment request message using a consumer device to a payment processing network, where the payment request message comprises an amount of money to be paid and an alias, where the alias is associated with a payee; code for receiving in response to the payment request message an authentication request message, where the authentication request message is received via the portable consumer device; and code for sending an authentication token in response to the authentication request message.
The portable consumer device 32 may further include a contactless element 32(g), which is typically implemented in the form of a semiconductor chip (or other data storage element) with an associated wireless transfer (e.g., data transmission) element, such as an antenna. Contactless element 32(g) is associated with (e.g., embedded within) portable consumer device 32 and data or control instructions transmitted via a cellular network may be applied to contactless element 32(g) by means of a contactless element interface (not shown). The contactless element interface functions to permit the exchange of data and/or control instructions between the mobile device circuitry (and hence the cellular network) and an optional contactless element 32(g).
Contactless element 32(g) is capable of transferring and receiving data using a near field communications (“NFC”) capability (or near field communications medium) typically in accordance with a standardized protocol or data transfer mechanism (e.g., ISO 14443/NFC). Near field communications capability is a short-range communications capability, such as RFID, BluetoothTM, infra-red, or other data transfer capability that can be used to exchange data between the portable consumer device 32 and a payment processing network 26 or it can be used to exchange data between the portable consumer device 32 and an access device (e.g., a POS terminal). Thus, the portable consumer device 32 is capable of communicating and transferring data and/or control instructions via both cellular network and near field communications capability.
The portable consumer device 32 may also include a processor 32(c) (e.g., a microprocessor) for processing the functions of the portable consumer device 32 and a display 32(d) to allow a payee to see phone numbers and other information and messages. The portable consumer device 32 may further include input elements 32(e) to allow a payee to input information into the device, a speaker 32(f) to allow the payee to hear voice communication, music, etc., and a microphone 32(i) to allow the payee to transmit her voice through the portable consumer device 32. The portable consumer device 32 may also include an antenna 32(a) for wireless data transfer (e.g., data transmission).
Any of the above-described methods or steps of such methods may be embodied as software code to be executed by a processor of the server computer or any other suitable combination of devices using any suitable computer language such as, for example, Java, C++ or Perl using, for example, conventional or object-oriented techniques.
