An apparatus, system and method whereby a single apparatus, with both electronic identity and optical identity is used to identify a customer or user. The electronic identity is provided by a Radio Frequency Identification (RFID) circuit in the apparatus, while the optical identity is provided by a 1D or 2D barcode affixed to the apparatus. When the apparatus is scanned at a point-of-sale system with an RFID or barcode reader, the appropriate identity is provided to the point-of-sale system, thereby allowing a customer to link the transaction with a customer account.
