What Are RFID Wristbands?
RFID wristbands are wearable devices with a tiny chip and antenna embedded inside. This chip communicates with RFID readers through radio waves, allowing fast and contactless identification.
How RFID Wristbands Work:
When a wristband comes close to an RFID reader, the reader emits a signal.
The chip inside the wristband responds with the stored data.
The system processes the information in real time, enabling functions like entry access, payments, or medical record retrieval.
Types of RFID Wristbands:
Low-Frequency (LF) – Operates within a short range (up to 10 cm). Often used for secure access control.
High-Frequency (HF/NFC) – Works up to 10 cm but is compatible with smartphones. This makes it a popular choice for events, payments, and transport.
Ultra-High-Frequency (UHF) – Can be scanned from several meters away, making it ideal for hospitals, logistics, and large-scale asset tracking.
