An earlier smartphone payments system from Think Computer Corporation, Palo Alto, California that replaced the plastic debit card. Anyone with a smartphone could use it by opening and depositing funds into a FaceCash account. When making a purchase at a store, the merchant scanned a barcode displayed on the phone, and a photo of the customer's face was sent to the cash register for visual ID. A mobile app could also store the barcodes from other loyalty and ID cards. See
Web payment service.
