Abstract

A payment system and method of conducting a shopping transaction between a customer and a merchant utilizing an approval system over portable phone which controls the acceptance or rejection of the shopping transaction and a financial institution to provide credit or an account that can be debited to pay for the shopping transaction. A first communications link is used between the merchant and the computer approval system and a first customer identification code given by the customer to the merchant is transmitted over the first communications link to the computer approval system for validation thereby. If the first customer identification code is validated by the computer approval system, the computer approval system uses a different, second communications link to a portable wireless telephone that can be a cell phone to obtain the customer approval of the transaction and to obtain from the customer a second customer identification code. If this second customer identification code is validated by the financial institution, then the computer approval system transmits an approval of the transaction to the merchant over the first communications link. The shopping transaction can take place at a Point of Sale in which case the merchant utilizes a POS device for communicating with the computer approval system; and it can take place over the Internet in which case the merchant utilizes a web site for communicating with the customer.

a sales device used by a merchant that can communicate over a second communication link that is separate and not associated with said first communication link, said sales device being capable of transmitting over said second communication link a merchant identification code, the transaction amount, and a buyer semi-secure User ID and of receiving an acceptance/rejection indication; and

a system computer device that is connected to said portable communication device over said first communication link and connected to said sales device over said second communication link,

said system computer device capable of receiving and processing said PIN and said acceptance or rejection of the sales transaction from the buyer and capable of transmitting transaction information to said buyer, all over said first communication link, and

said system computer device capable of sending and receiving over said second communication link the merchant identification code, the transaction amount, and the buyer semi-secure User ID and of receiving over said second communication link an acceptance/rejection indication.
