For RFID products, we are able to encode and verify the RFID performance, so that we can deliver products with certain specifications. The encoding can be paired with visual codes or numbers, or created from a given list; or each RFID product can be checked performance-wise, so that only products with the requested performance are delivered.
We can even perform a 100% stress test on each product. This guarantees that antennas, or often IC connections, are 100% controlled for all products delivered. Tags with irregular performance will then be removed and replaced, so there are 100% quality-verified tags on the reels.
