Pairing a payment object reader with a point-of-sale terminal

A system comprising:

• a point-of-sale (POS) device comprising:
• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions executable by the one or more processors, wherein the instructions cause the one or more processors to perform acts comprising:
• determining, at a first time via a wireless transceiver of the point-of-sale (POS) device while in a pairing mode, first signal strengths of wireless signals emitted by wireless transceivers of a plurality of payment object readers, wherein each of the plurality of payment object readers is configurable to be paired wirelessly with the POS device, and wherein each of the first signal strengths indicates a location of the respective payment object reader relative to the POS device at the first time;
• causing presentation of, on a user interface of the POS device, and in near real-time to determining the first signal strengths, a list of the plurality of payment object readers, wherein the list is ordered by respective first signal strengths of each of the plurality of payment object readers;
• determining, at a second time via the wireless transceiver, second signal strengths of the wireless signals emitted by the wireless transceivers, wherein each of the second signal strengths indicates a location of the respective payment object reader relative to the POS device at the second time;
• causing presentation of, on the user interface, and in near real-time to determining the second signal strengths, an updated list of the plurality of payment object readers, wherein the updated list is ordered by respective second signal strengths of each of the plurality of payment object readers;
• and
• based at least in part on (1) a particular second signal strength of a particular payment object reader of the plurality of payment object readers satisfying a threshold value and (2) a difference in a first signal strength and the particular second signal strength of the particular payment object reader indicating movement by the particular payment object reader toward the POS device, establishing a wireless communication channel between the particular payment object reader and the POS device, wherein establishing the wireless communication channel is further in response to selection of a selection mechanism displayed via the user interface.

One or more non-transitory computer-readable media of a point-of-sale (POS) device storing instructions executable by one or more processors that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:

• determining, at a first time via a wireless transceiver of the point-of-sale (POS) device while in a pairing mode, first signal strengths of wireless signals emitted by wireless transceivers of a plurality of payment object readers, wherein each of the plurality of payment object readers is configurable to be paired wirelessly with the POS device, and wherein each of the first signal strengths indicates a location of the respective payment object reader relative to the POS device at the first time;
• causing presentation of, on a user interface of the POS device, and in near real-time to determining the first signal strengths, a list of the plurality of payment object readers, wherein the list is ordered by respective first signal strengths of each of the plurality of payment object readers;
• determining, at a second time via the wireless transceiver, second signal strengths of the wireless signals emitted by the wireless transceivers, wherein each of the second signal strengths indicates a location of the respective payment object reader relative to the POS device at the second time;
• causing presentation of, on the user interface, and in near real-time to determining the second signal strengths, an updated list of the plurality of payment object readers, wherein the updated list is ordered by respective second signal strengths of each of the plurality of payment object readers;
• and
• based at least in part on (1) a particular second signal strength of a particular payment object reader of the plurality of payment object readers satisfying a threshold value and (2) a difference in a first signal strength and the particular second signal strength of the particular payment object reader indicating movement by the particular payment object reader toward the POS device, establishing a wireless communication channel between the particular payment object reader and the POS device, wherein establishing the wireless communication channel is further in response to selection of a selection mechanism displayed via the user interface.
