<p>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.</p> |
