20090030845 | SYSTEM AND METHOD FOR ACCOUNT IDENTIFIER OBFUSCATION - A method is disclosed. The method includes generating an obfuscated portion using a dynamic cryptogram unique to a transaction, where the dynamic cryptogram is determined using a uniquely derived key. The method also includes replacing a middle portion of the account identifier with the obfuscated portion to form an obfuscated account identifier. | 01-29-2009 |
20090265260 | PREPAID CHIP CARD EXCEPTION PROCESSING - A portable consumer device may have money stored therein, which can be calculated using an accumulator record and an exception record. The accumulator record can be incremented by the amount of any initiated transaction using the portable consumer device. The exception record can be incremented by the amount of any completed transaction using the portable consumer device. The portable consumer device may also have a limit amount, to record the amount of money added. The records allow for a later reconstruction of the device history, and can account for any errors or problems during transactions. | 10-22-2009 |
20090265271 | PREPAID PORTABLE CONSUMER DEVICE INCLUDING ACCUMULATOR - A portable consumer device may have money stored therein, which can be calculated using an accumulator record. The accumulator record can be incremented by the amount of any transaction using the portable consumer device. The accumulator record can retain the value of the prior transactions, upon additional funds being collected on the portable consumer device. | 10-22-2009 |
20100211498 | RECORDATION OF ELECTRONIC PAYMENT TRANSACTION INFORMATION - A system, apparatus, and method for processing payment transactions that are conducted using a mobile device that includes a contactless element, such as an integrated circuit chip. An account holder is enabled to generate transaction related data and append that data to a transaction record or transaction identifier. The appended data and transaction record or identifier may be stored in the mobile payment device and/or provided to an Issuer. If provided to an Issuer, the transaction related data generated by the account holder may be used to supplement an account statement. The additional information generated by the account holder may be used to assist the account holder in determining if a transaction is valid by providing information that helps the account holder to recall the location or other aspect of the transaction. | 08-19-2010 |
20100211504 | METHOD OF PERFORMING TRANSACTIONS WITH CONTACTLESS PAYMENT DEVICES USING PRE-TAP AND TWO-TAP OPERATIONS - A system, apparatus, and method for processing payment transactions that are conducted using a mobile payment device that includes a contactless element, such as an integrated circuit chip. The invention enables one or more of the operations of activation of a payment application, transfer of transaction data, updating of account records, setting or re-setting of a payment application counter or register, or transfer or processing of a script, command, or instruction, with these functions being performed with minimal impact on a consumer. This is accomplished by introducing a pre-tap and/or two-tap operation prior to, or as part of, the transaction flow. | 08-19-2010 |
20100211507 | OVER THE AIR UPDATE OF PAYMENT TRANSACTION DATA STORED IN SECURE MEMORY - A system, apparatus, and method for processing payment transactions that are conducted using a mobile device that includes a contactless element, such as an integrated circuit chip. The invention enables the updating, correction or synchronization of transaction data maintained by an Issuer with that stored on the device. This is accomplished by using a wireless (cellular) network as a data communication channel for data provided by an Issuer to the mobile device, and is particularly advantageous in circumstances in which the contactless element is not presently capable of communication with a device reader or point of sale terminal that uses a near field communications mechanism. Data transferred between the mobile device and Issuer may be encrypted and decrypted to provide additional security and protect the data from being accessed by other users or applications. If encryption keys are used for the encryption and decryption processes, they may be distributed by a key distribution server or other suitable entity to a mobile gateway which participates in the data encryption and decryption operations. | 08-19-2010 |
20100217709 | APPARATUS AND METHOD FOR PREVENTING UNAUTHORIZED ACCESS TO PAYMENT APPLICATION INSTALLED IN CONTACTLESS PAYMENT DEVICE - A system, apparatus, and method for preventing the unauthorized access to a payment application installed on a mobile payment device, or to transaction data stored in the device. The mobile payment device may be a mobile phone that includes a contactless element (such as a contactless smart chip) and that is capable of communication and data transfer using a wireless communications network and a near field communications capability. Unauthorized access to the payment application is prevented by requiring that access control data be received from a trusted source, such as a controller or application in charge of managing inputs from a phone keypad, in order to activate the payment application or to access stored data. | 08-26-2010 |
20130204794 | PAYMENT SERVICE AUTHENTICATION FOR A TRANSACTION USING A GENERATED DYNAMIC VERIFICATION VALUE - Methods and systems for dynamically generating a verification value for a transaction and for utilizing such value to verify the authenticity of the payment service application. The dynamically created verification value may be generated on a payment device, such as an integrated circuit credit card or smart card, embedded into the payment data, and transmitted to a point of sale terminal. Alternatively, payment data is sent by a payment device to a point of sale terminal, which generates a verification value and embeds it into the payment data. The embedded verification value is used by a service provider to verify the authenticity of the transaction. The methods and systems may be used in a contactless (wireless) environment or a non-wireless environment. | 08-08-2013 |
20130226802 | VERIFICATION VALUE SYSTEM AND METHOD - A method is disclosed. The method includes generating a verification value in response to a transaction involving a portable consumer device, where the verification value is generated using a first dynamic data element and a second dynamic data element. The verification value is sent to a service provider associated with the portable consumer device so that the service provider can verify the transaction. | 08-29-2013 |
