Abstract: A payment-enabled mobile device is placed in communication with a POS (point of sale) terminal to facilitate a purchase transaction. A user selects a payment account in the payment-enabled mobile device. Payment credentials are transmitted from the payment-enabled mobile device to the POS terminal. The payment credentials include a PAN-length identifier that identifies an issuer of the selected payment account.

Abstract: Transaction data is obtained relating to a current purchase transaction. An account indicator is retrieved. The transaction data is used to transform the account indicator. The transformed account indicator is encrypted to generate an encrypted account indicator.

Abstract: A computer-implemented method for detecting compromised automated teller machines is provided. The method includes receiving activity data from an ATM, activity data including user input data and machine data, wherein user input data includes instructions input by a user at the ATM during a transaction, and wherein machine data is associated with processes performed by the ATM; storing operating parameter rules in the memory, the operating parameter rules configured to indicate whether the received activity data is within a normal activity range for the ATM; applying the received activity data to the operating parameter rules; generating an activity score for the ATM based on the applying, wherein the activity score is configured to indicate a likelihood that the ATM is compromised; and initiating a response based on the activity score.

Abstract: At the point of sale, a user of a payment-enabled mobile device opens a wallet application program and selects a payment account for use in a purchase transaction. The user is prompted to select a sub-account from among a number of sub-accounts associated with the selected payment account. The user selects one of the sub-accounts, and the transaction is ultimately assigned to the selected sub-account by the account issuer. Assignment of transactions to sub-accounts is reflected in payment account statements rendered to the user by the account issuer.

Abstract: A computer-implemented method for generating environmental impact offsets for payment card transactions is described. The method implemented using a computing device in communication with a memory. The method includes storing, in the memory, a plurality of offset factors associated with a plurality of merchants, receiving a first authorization request message for a payment transaction originating from an originating merchant for a cardholder that includes a transaction amount, determining the offset factor associated with the originating merchant, calculating, by the computing device, an offset amount based on the transaction amount and the offset factor, outputting the offset amount.
