1. A method for testing radio frequency identification (RFID) tags, comprising:
- (a) receiving a tag having an antenna formed on a substrate, and an integrated circuit on the substrate electrically coupled to the antenna;
(b) physically contacting a test probe to the antenna;
(c) conducting at least one test signal through the test probe to the antenna;
(d) receiving a response signal from the antenna through the test probe, the response signal being generated by the integrated circuit; and
(e) analyzing the response signal.

Abstract
Methods, systems, and apparatuses for testing radio frequency identification (RFID) tags are described. The tags are tested using a direct connection scheme, where a testing apparatus makes direct contact with a portion of a tag in order to perform a test on the tag. For example, the testing apparatus may read data from the tag to verify operation. Any number of tags may be tested at a time, including one tag at a time, or multiple tags in parallel.
