1. A system for testing operationality of a battery-free wireless tag that has at least one antenna for far field wireless communication and employs at least one low energy wireless communication protocol, the system comprising:
a near field antenna; and
a fixture for positioning the wireless tag so that the at least one antenna for far field wireless communication of the wireless tag is within a near field of the near field antenna of the system;
wherein when the wireless tag is positioned by the fixture, the wireless tag is within an at least a partly open chamber;
wherein the entirety of the testing of the wireless tag is performed when the at least one antenna for far field wireless communication of the wireless tag is within a near field produced by the near field antenna of the system;
wherein during testing, in order to test the wireless tag the near field antenna of the system is used to both transmit a wireless signal supplying operating energy to the wireless tag and to communicate with the wireless tag; and
wherein a pass result for the wireless tag requires the system to receive a message from the wireless tag in conformance with the at least one low energy wireless communication protocol within a specified time range after the system transmits the wireless signal supplying operating energy to the wireless tag.
