1. A method for testing a wireless tag by a testing unit, comprising:
transmitting, by a first antenna of the testing unit, a prescribed pattern that is recognizable by a wireless tag to put the wireless tag into a testing mode;
transmitting a trigger signal to a wireless tag from a second antenna of the testing unit, the trigger signal being adapted to cause a wireless tag to at least respond with a prescribed signal when the wireless tag is good;
waiting up to a prescribed amount of time after transmission of the trigger signal for a response to the trigger signal from a wireless tag that is within range of the second antenna;
when a valid response is received from the wireless tag within the prescribed amount of time, designating the wireless tag as having passed the test; and
when a valid response is not received from the wireless tag within the prescribed amount of time, designating the wireless tag as having failed the test.
