There are two types of RFID tags: active and passive tags. Active tags contain a battery and can transmit its signal autonomously; passive tags don’t have a battery and require an external source to initiate signal transmission.
Jim Beisel, the company’s special account manager for Garden Grove, California-based All Barcode Systems, said security is one of the things the company is focusing on. Beisel explained the company is working with school districts on an RFID badge that would be used to track visitors. “The person will get a badge with an RFID chip and then log in as a visitor,” Beisel explained. “But it won’t just track the person’s in and out [of the building]. It will have traceability. It will provide schools with a visitor’s location.”
