ABS RFID key fob is made of brand new colorful hard plastic, which is widely used in RFID management applications such as access control, identification, loyalty systems, etc.
An RFID keyfob is a portable, contactless device that uses radio waves to communicate with an RFID reader. It's essentially a compact electronic tag, typically shaped like a keychain token, made from plastic or durable resin. Inside the fob is a tiny microchip (which stores information, such as a unique ID) and an antenna (which transmits and receives data). When held near an RFID reader, the keyfob wirelessly transmits its data using electromagnetic fields.
