Abstract: A bank identity for an electronic payment tool of a user is created by an e-receipt company computer system and it is associated with a user identity. The bank identity is sent to a bank computer system and it gets associated with a bank account maintained at a financial institution. The bank identity and a transaction details data are sent to the e-receipt company computer system and to a store system upon receiving a request for payment with use of the electronic payment tool at the store system. The store system sends a receipt data and the transaction details to the electronic receipt company computer system. The e-receipt company computer system combines the user identity, the receipt data and the transaction details data based on a transaction identity included in the transaction details data to generate an electronic receipt which is made accessible through a client device over a network.
