Abstract
Systems, methods, and computer program products are provided for using proximity sensing systems, such as Bluetooth low energy (LE) beacons, to uniquely identify remote computing systems, such as point of sale terminals. A mobile device includes an antenna, a baseband modem, and a contactless frontend, and is able to perform near-field communication transactions. The mobile device antenna receives radio communications from one or more Bluetooth LE beacons, the transmissions including data packets with a unique identifier. The mobile device calculates the signal strength of the one or more Bluetooth LE beacons at a time proximate to when a near-field communication transaction is initiated. The mobile device stores in its memory the data packet associated with the Bluetooth LE beacon broadcasting the strongest signal.
