SYSTEM AND METHOD FOR APPROVING TRANSACTIONS

摘要

In a transaction between a merchant and a payer, approval of the transaction may be provided by a payment processing system using authentication information provided from a mobile device of the payer. The authentication information may include a location of the payer mobile device which may be compared to a location of a merchant payment device such that the transaction is approved if the payer mobile device is within a defined distance of the merchant payment device.
