The American financial Corporation American Express (Amex) has applied for a patent for a blockchain system to capture and transmit images of cash receipts. The relevant information was published on November 13
The author of the application is the division of the Corporation for the tourism sector, Amex. The proposed solution allows the user to fix the image of the cash receipt or receipt using a mobile device. Then, using "optical character recognition", the system decrypts the image and compares the data with the transaction history records.
The system uses "data blocks", and, as specified in the application,"these databases can have a relational, hierarchical, graphical, distributed and any other object-oriented structure."
