A RFID device with a surface treatment which interferes with the
transmission of RF signals/data between the RFID device and the RF
interrogator or reader. A surface treatment of either RF reflective or RF
absorptive ink is deposited on a RFID device using an attenuation pattern
to fine tune the read range of the RFID device thereby eliminating or
reducing the occurrence of accidental or cross reads between nearby RF
interrogators or readers.The surface layer may be deposited at the time
of printing the labels thereby fixing the attenuation at a known level or
the surface treatment may be applied in an on-demand fashion allowing the
attenuation level to be varied to an individual requirement.
