Abstract
An electromagnetic interposer circuit is attachable to an article that is also equipped with an anti-counterfeit and anti-theft/tracking electromagnetic marker. The interposer circuit includes a first interface for exchanging electrical signals with the marker at a first, shorter, communication range and a second interface coupled to the first interface for exchanging electromagnetic signals with a reader at a second, longer, communication range. The first and second interfaces exchange signals with the marker and the reader, respectively, over a radiofrequency bandwidth that includes a first frequency band and a second frequency band. A filter circuit block within the interposer circuit between the first interface and the second interface operates to block the transfer of signals between the first interface and the second interface over the first frequency band.
