RFID wristband
Wearables & cards
What is it?
RFID wristbands embed a chip and antenna in a band worn on the wrist. Disposable versions (Tyvek, paper, vinyl) are used for events and hospitals, while reusable silicone wristbands are used for access control, cashless payment at festivals, and theme parks. Wristbands are the main way RFID is deployed for people identification in non-card form factors.
How it works
An HF or NFC inlay is embedded in the wristband material – either heat-sealed inside Tyvek/vinyl or moulded into silicone. The antenna is designed to work against the human wrist (which is lossy at RF frequencies). NFC wristbands use ISO 14443 for tap-and-go interaction; UHF wristbands enable longer-range identification for attendance tracking.
