SYSTEM AND METHOD FOR GENERATING A SINGLE-USE TIME-LIMITED PURCHASE CODE FOR COMPLETING TRANSACTIONS WITH A PORTABLE COMPUTING DEVICE

摘要

A request for a purchase code may be received from a portable computing device (PCD) from a communications network. The request may further include a purchase amount and location information of the PCD. The system determines if a funding account has sufficient funds to cover the purchase amount. If the funding account has sufficient funds to cover the purchase amount, then the system generates a single-use time limited purchase code to the PCD. The system may receive the purchase code from a POS terminal and then it may determine if the received purchase code matches purchase code issued to the PCD. The system may compare the location of the PCD against the POS terminal. If a requested transaction amount is less than or equal to the purchase amount and if the purchase codes and location information match, then they system may generate a message approving the transaction.
