Abstract

A method and a system directed to location-based services within a wireless telecommunications or data communications network, and more particularly to other technical fields such as technologies used to authenticate secure payment card transactions, technologies to verify and validate payment card user identities, and for use with any application where the results of comparing two or more geographic locations has some utility or value. The method includes receiving information from a transaction device involving a payment card holder initiating a payment card transaction; identifying a location of the transaction device; identifying a location of a mobile device associated with the payment card holder; comparing the location of the transaction device with the location of the mobile device to determine a relative degree of proximity of the transaction device with the mobile device; and assessing the determined relative degree of proximity to determine whether the payment card transaction is valid or invalid.
