  • Method and apparatus for determining adjacency of wireless device to POS terminal
    Publication number: 20060084448
    Abstract: One or more stationary wireless readers are used to determine the relative strength of calibration signals sent from fixed locations adjacent to POS terminals. Then, the signal strength of signals being transmitted by wireless devices within range of the one or more wireless readers is evaluated to determine the relative position of each wireless device to the POS terminals. This allows an operator of the POS system to determine the proximity of each wireless device relative to the POS terminals.
