Abstract: Processing of point of sale (“POS”) redemptions via a “tap” of a contactless device comprises a POS data collector that facilitates a connection with a contactless device. A merchant scans items for purchase using a POS scanner, which captures product identification information. The POS scanner forwards the product identification information to a POS terminal. The POS data collector intercepts the product identification information between the POS scanner and the POS terminal. A user taps the contactless device in the POS data collector's radio frequency field, and a communication channel is established between the contactless device and the POS data collector. The POS data collector identifies the user via the contactless device and identifies coupons, merchant offers, and other value-added services to redeem with the transaction. The POS data collector forwards this information to the POS terminal, the redemptions are applied to the transaction, and the communication is terminated.

Abstract: Using a Bluetooth communication channel for point of sale processing simulates a near field communication connection. A contactless device and the point of sale reader establish an unsecure communication channel. The user taps the contactless device with a point of sale terminal reader. The contactless device creates receive signal strength indicator (“RSSI”) value spikes. The terminal reader measures the RSSI values and transmits them to the contactless device, which determines if the RSSI value reaches or exceeds a threshold configured for the contactless device. If the threshold is reached, the terminal reader and the contactless device establish a secure communication connection. The devices communicate via the secure communication connection, and the connection is terminated when a request to terminate is received.
