Abstract:
1. A computer-implemented method for detecting a tap of a mobile communication device with a point of sale system, comprising: establishing a first communication channel by a point of sale (“POS”) device with a mobile communication device; detecting, by the POS device, receive signal strength indicator (“RSSI”) value spikes based on the strength of a signal from the mobile communication device, as observed by the POS device when the mobile communication device is moved in proximity to the POS device; transmitting, by the POS device, an RSSI value monitored during a predetermined period of time to the mobile communication device; receiving, by the POS device, a request to establish a second communication channel with the mobile communication device in response to a determination that the RSSI value monitored during the predetermined period of time meets or exceeds a threshold value established for the mobile communication device; communicating, by the POS device, an authorization to establish the second communication channel with the mobile communication device; and communicating, by the POS device, information to and receiving, by the POS device, information from the mobile communication device via the second communication channel.
