Abstract
According to various aspects and technical advantages, an apparatus for electronic shelf labels includes a controller circuit for communicating with communication devices using a contactless communication protocol, a set of two or more antenna coils, each antenna coil located at a known position relative to the controller circuit, and a switch for selectively coupling the controller circuit to one or more of the set of antenna coils. The controller circuit is configured to determine a physical location of a communication device based on which antenna coil from the set of antenna coils the communication device is using to communicate with the controller circuit
