Abstract: A user may claim to have not made or allowed a transaction and that the transaction was made in error. Where it appears the user has not authorized the transaction, the funds of the transaction are returned to the user, or are charged back. Systems and methods provide a way to confirm whether or not a transaction was actually authorized by the user, thereby settling a chargeback dispute for a previously executed transaction. The method comprises receiving the dispute regarding the transaction including associated transaction data, and retrieving a digital signature associated with the transaction data, the digital signature computed by signing the transaction data. The digital signature is then verified using a public key, wherein the public key corresponds to a private key stored on a mobile device. It is then determined whether or not the transaction is fraudulent based on a verification result of the digital signature.

IPC: G06Q30/00
Filed: 2009-12-04
Abstract: Processing transactions involving private label portable consumer devices is presented. For a transaction involving a portable consumer device in a payment processing network, an authorization request from a merchant is received by a transaction handler. The transaction handler, in communication with the issuer, denies or approves the transaction. For approved transactions, the merchant sends a settlement request to the transaction handler. If the transaction is identified as involving a private label portable consumer device, the transaction handler applies a custom settlement arrangement rate to the payment sought, generally reducing the payment amount. The applied payment amount is received from the issuer and forwarded to the merchant. If the applied payment amount is less than the actual amount owed to the merchant, the merchant sends a request to the issuer of the private label payment device to settle the transaction in accordance with a custom settlement agreement.
