SYSTEM AND METHOD OF PROCESSING POINT-OF-SALE PAYMENT TRANSACTIONS VIA MOBILE DEVICES
A system and method for processing POS payment transactions via mobile devices is described. Encrypted first identification information is received from a merchant mobile device. Encrypted second identification information is received from a cardholder mobile device. A determination is made regarding whether the encrypted first identification information and the encrypted second identification information are associated with one another. In response to a determination that the determination that the encrypted first identification information and the encrypted second identification information are associated with one another, the encrypted first identification information and the encrypted second identification information are decrypted. The POS payment transaction is processed based on the decrypted first and second identification information.
1 . An adaptive payment server for processing a POS payment transaction comprising:
a processor configuring the server to:
receive, from a merchant mobile device, an encrypted first identification information that identifies a payment account and a payment amount;
receive, from a cardholder mobile device, encrypted second identification information that is used to authenticate the POS payment transaction;
determine whether the encrypted first identification information and the encrypted second identification information are associated with one another;
decrypt the encrypted first identification information and the encrypted second identification information; and
process the POS payment transaction based on the decrypted first identification information and the decrypted second identification information.
2 . The adaptive payment server of claim 1 , wherein the encrypted first identification information includes an encrypted debit card number.
3 . The adaptive payment server of claim 1 , wherein the encrypted second identification information includes an encrypted Personal Identification Number (“PIN”).
4 . The adaptive payment server of claim 1 , wherein the server configured to determine whether the encrypted first identification information and the encrypted second identification information are associated with one another is further configured to:
receive merchant location information associated with the merchant mobile device;
receive cardholder location information associated with the cardholder mobile device;
determine proximity of the merchant mobile device and the cardholder mobile device based on the merchant location information and the cardholder location information; and
determine whether the encrypted first identification information and the encrypted second identification information are associated with one another based on the determined proximity.
5 . The adaptive payment server of claim 1 , wherein the server is further configured to:
in response to receiving the encrypted first identification information, generate a transaction identifier that uniquely identifies the POS payment transaction; and
communicate the transaction identifier to the merchant mobile device.
6 . The adaptive payment server of claim 1 , wherein the server configured to determine whether the encrypted first identification information and the encrypted second identification information are associated with one another is further configured to:
receive, from the cardholder mobile device, a transaction identifier associated with the POS payment transaction;
compare the received transaction identifier with a list of transaction identifiers, wherein each transaction identifier in the list of transaction identifier comprises a transaction identifier communicated by the server to one or more merchant mobile devices;
determine whether the encrypted first identification information and the encrypted second identification information are associated with one another based on the comparison.
7 . The adaptive payment server of claim 1 , wherein the server is further configured to:
authenticate identification of the payment account based on the second identification information; and
initiate a debit of the payment amount from the identified account.
8 . The adaptive payment server of claim 1 , wherein the server is configured to process the POS payment transaction via an EFT network.
9 . The adaptive payment server of claim 8 , wherein the server is configured to generate an EFT request to the EFT network.
10 . The adaptive payment server of claim 1 , wherein the first identification information and the second identification information are encrypted using the same encryption technique.
11 . A method for processing a POS payment transaction, the method comprising:
receiving, from a merchant mobile device, an encrypted first identification information that identifies a payment account and a payment amount;
receiving, from a cardholder mobile device, encrypted second identification information that is used to authenticate the POS payment transaction;
determining whether the encrypted first identification information and the encrypted second identification information are associated with one another;
decrypting the encrypted first identification information and the encrypted second identification information; and
processing the POS payment transaction based on the decrypted first identification information and the decrypted second identification information.
12 . The method of claim 11 , wherein the encrypted first identification information includes an encrypted debit card number.
13 . The method of claim 11 , wherein the encrypted second identification information includes an encrypted Personal Identification Number (“PIN”).
14 . The method of claim 11 , wherein said determining whether the encrypted first identification information and the encrypted second identification information are associated with one another further comprising:
receiving merchant location information associated with the merchant mobile device;
receiving cardholder location information associated with the cardholder mobile device;
determining proximity of the merchant mobile device and the cardholder mobile device based on the merchant location information and the cardholder location information; and
determining whether the encrypted first identification information and the encrypted second identification information are associated with one another based on the determined proximity.
15 . The method of claim 11 , further comprising:
in response to receiving the encrypted first identification information, generating a transaction identifier that uniquely identifies the POS payment transaction; and
communicating the transaction identifier to the merchant mobile device.
16 . The method of claim 11 , wherein said determining whether the encrypted first identification information and the encrypted second identification information are associated with one another further comprising:
receiving, from the cardholder mobile device, a transaction identifier associated with the POS payment transaction;
comparing the received transaction identifier with a list of transaction identifiers, wherein each transaction identifier in the list of transaction identifier comprises a transaction identifier communicated by the server to one or more merchant mobile devices;
determining whether the encrypted first identification information and the encrypted second identification information are associated with one another based on the comparison.
17 . The method of claim 11 , further comprising:
authenticating identification of the payment account based on the second identification information; and
initiating a debit of the payment amount from the identified account.
18 . The method of claim 11 , wherein the POS payment transaction is processed via an EFT network.
19 . The method of claim 18 , wherein the POS payment transaction is processed by generating an EFT request to the EFT network.
20 . The method of claim 11 , wherein the first identification information and the second identification information are encrypted using the same encryption technique.
