Title
(EN) Smart label reader interfacing device
Abstract
(EN)
A reader interfacing device 125 for providing a communication path between a tag or smart label reader 20 operating at a first frequency; and a remote tag or smart label 110 operating at a second frequency, the first and second frequency being mutually different by at least an order of magnitude, and the reader being operable to communicate through the device to the remote tag or smart label. The device includes a power supply 140 for converting interrogating radiation received at the device from the reader to generate power supply potentials for powering the device. The device includes a loop antenna for magnetically coupling to a corresponding loop antenna of the reader. Provides the advantage that the reader can conform to a standard ISO 15693 and the device enables remote tags and smart labels not conforming to the standard to communicate with the reader.
