Creating Chemical-Free RFID Tags

One way to produce RFID tags is to use chemicals to etch the antennas. But doing so requires potentially dangerous chemicals, such as phosphoric acid, acetic acid, and nitric acid. We’ve innovated new manufacturing methods including cutting the antenna material with dies and lasers rather than through chemical etching. This avoids the use of harmful chemicals and makes it possible to recycle the matrix from our RFID rolls—some 127,000 pounds to date.
