Abstract
RFID devices for use in electronic surveillance article ('EAS') systems may be differently configured, resulting in different performance at the operating frequency or range of frequencies of an EAS system. The performance of differently configured RFID devices may be converged or rendered substantially similar by testing the performance of such RFID devices in a range of frequencies. At least one of the RFID devices is reconfigured to converge the performance of the RFID devices in the range of frequencies if the performance of the RFID devices is not sufficiently similar. This may include changing the configuration of an antenna, an RFID chip, and/or a non-functional component of an RFID device and/or the location in which an RFID device is associated to an article. Differently configured RFID devices may all be manufactured from the same initial configuration, with different RFID devices being differently processed before incorporation in an EAS system.
