Edgar Alvarez: How RFID tags became trendy

Fashion brands are using the tech to battle counterfeits and track inventory more efficiently.

As far as wireless technologies go, radio-frequency identification (RFID) is one of the oldest. Patented in 1983 by the late British inventor Charles Walton, RFID made it possible for new, cutting-edge tech such as near-field communication (NFC) to exist. As with NFC, RFID chips are used to store information digitally, which can then be shared between objects through electromagnetic fields and radio waves. It may not be sexy, but companies see real potential in the technology, no matter how old. It's no surprise, then, that over the past few years RFIDs have become ubiquitous in a wide range of industries, including travel, sports and one you wouldn't expect: fashion.
