System for secured transactions over a wireless network

摘要

A system for implementing a method that books and pays a retailer having a POS connected to a transaction server storing confidential user information including a retailer identification, a user code, and a user wireless device phone number. The method includes: receiving at the transaction server, from the user wireless device which can be a cell phone, an SMS containing a retailer identification; reading at the transaction server the phone number of the wireless device communicated by the carrier transporting the SMS; authentifying the phone number and retailer identification with the stored confidential user information; sending the user confidential information to the retailer POS. The user enters on the POS the user code. The POS reads and authentifies the user code with the user confidential information received from the transaction server. The retailer enters the payment information on the POS and sends it with user information to the transaction server.
