RFID has been around for decades. Now it’s becoming retailers’ best crime-fighting tool

An increasing number of retailers are dusting off a decades-old technology in order to streamline their inventory management, and some experts believe it could go far in tightening up the industry’s loose accounting of shrink and theft.
Radio-Frequency Identification (RFID) tech evolved from work in radar around WorldWar II, and has had many applications since, according to the Institute of Electrical and Electronics Engineers. It employs various radio frequencies to transmit information between a stationary location and an objector between objects, including moving objects.
