Passive UHF tags is working reliably in harsh environments that deal with metals and liquids. The fact of the matter is RFID, like other technologies, is subject to the laws of physics. Radio waves and metals don’t work well. If you have metal environment, the radio wave is reflected, if you have liquids such as a water environment, they’re absorbed. What we did with our technology is address that issue head on and solved it with a disruptive technology that allows our products, our tags, including the UHF tags which is a finalist, to be able to operate reliably in harsh environments.
