RFID (Radio Frequency Identification) wristbands use embedded RFID tags—tiny microchips equipped with antennas—to wirelessly transmit information to a scanner. Unlike QR codes or barcodes, RFID tags don’t need line-of-sight and can function through fabric, plastic, or vinyl.
RFID badges are another popular form factor for access control at events, offering similar benefits in a different wearable style.
There are three main types of RFID wristband chips:
- Passive tags (most common): no battery required, activated by the reader.
- Active tags: battery-powered, ideal for longer range or real-time tracking.
- Battery-assisted passive tags: a hybrid offering improved performance.
For example, an event organizer might use passive RFID wristbands to grant attendees access to different zones, while an instance of active tags could enable real-time tracking of VIP guests or facilitate cashless payments at concession stands.
Each band stores unique data, including personal information such as name and address, making RFID wristbands an ideal choice for identity verification, access control, event analytics, and seamless guest experiences.
