Abstract: The system tracks transaction information as it goes to the acquiring network; where it is associated with the card type, matched to the issuer, and sent via the IS08583 authorization stream for approval. Elements are extracted from the IS08583 message to represent the payment receipt then sent to and stored in a centralized payment receipt repository (CRR). A real-time record of the payment is recorded and a message confirmation notice is sent to the mobile device. The message confirmation sent to the mobile device contains merchant specific data. The real-time message contains transaction details and allows for additional functionality to classify the transaction as a “business” or “personal” expense or other expense type. Additional functionality allows a user to capture a photo of the payment receipt. All of the transaction, classification information, payment receipt photographs, and history is stored on backend servers and can be accessed via a user's account.
