RFID wristband is a wearable device embedded with a radio frequency identification (RFID) chip, enabling wireless communication with RFID readers.
An RFID wristband contains a 'smart tag' made up of an RFID chip and antenna. The tag can be in the form of a visible card (often made from plastic for durability) or it can be hidden or 'embedded' in other wristband materials like silicone and fabric.
