Abstract: Coupon information is provided electronically in association with receipts for transactions at physical stores and/or online stores. A retailer causes performance of a transaction in which one or more items are purchased. An interface configured to accept input indicating a customer identifier, such as an email address, associated with the transaction is provided. When input has been received via the interface, it is determined whether the identifier is associated with a known customer identity. If the customer identifier is associated with a known identity, digital coupons associated with that identity are applied against the transaction. An electronic receipt is further provided for the transaction via, for instance, the provided email address or a web-based application in which a session is established in connection with the identity.

Abstract: During a transaction involving a customer purchasing items at a terminal, one or more of coupon data, basket data, or a token are transferred between the terminal and a mobile device associated with the customer, via a proximity-based link. The proximity-based link may be established, without limitation, via NFC, RFID, or other short-range interfaces. For example, a customer may place an NFC component embedded in the customer's mobile device near an NFC component of the terminal. Various techniques are described for causing one or more coupons to be applied to the transaction based on the information transferred over the proximity-based link.
