Abstract
There is disclosed a printer having a print head and a high frequency magnetic coupler to magnetically couple with high frequency RFID transponders in a web at or near the print head. The coupler couples magnetically to only one transponder at a time that is generally aligned with one or more inductors, and magnetic radiation from the inductor(s) may be at least partly shielded from upstream transponders, and a grounded conductor in the upstream side of the coupler diminishes radiation to upstream transponders. One embodiment includes spaced inductors disposed along a generally transverse line across the web, and in another embodiment an elongate inductor extends along a line generally transverse of the web.
