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 payments service.

Web payments service

An online service that manages the transfer of funds from a customer to the merchant of an e-commerce website. The money may come from a prepaid account or credit card stored in a digital wallet in the user's device or stored in the service's datacenter.

Credit Cards and PayPal
In the late 1990s, many people were reluctant to pay for merchandise online via their credit cards. In addition, it was believed that information would be widely sold for a few cents (micropayments) per article. As a result, several payment systems emerged to make online payments more reassuring than credit cards. Most of them have faded or evolved into parts of other financial systems. Today, credit cards are widely used online, and PayPal has also endured with its various money transfer methods. See mobile payments service, PayPal, Bitcoin, Brodia, CyberCash, e-cash, eCharge, InternetCash, iPIN, Qpass, Windows Live ID and 1ClickCharge.
