RFID Chips & Frequencies for Wristbands

The chip is the part that has to match your system. This page lists every RFID chip family we commonly embed, the frequency and protocol behind it, and how to choose between LF, HF/NFC and UHF.

Frequency Bands

Three Frequency Bands

Each band solves a different problem. All three can be built into silicone, fabric, elastic, PVC, vinyl and wooden wristbands.

13.56MHz NFC Wristband

NFC wristbands use 13.56 MHz NFC Forum compatible chips such as NTAG213, NTAG215 and NTAG216, so a tap with a smartphone can open a URL, launch an app action, check in a guest or validate a ticket.

UHF Wristband

UHF RFID wristbands operate in the 860-960 MHz band and follow EPCglobal Gen2V2 / ISO/IEC 18000-63. They are read at a much longer distance than HF or LF wristbands, which makes them suitable for hands-free timing and crowd flow monitoring.

125kHz LF Wristband

125 kHz LF wristbands are low-frequency proximity credentials built around chips such as TK4100, EM4200/4305, T5577 and Hitag.

Selection Guide

How to Choose the Right Chip

Three checks before you place an order.

01

Match your reader

The reader and software decide the frequency. Send us the model number or an existing card and we will identify a compatible chip.

02

Decide the read distance

Tap-to-use actions suit 125 kHz and 13.56 MHz. Hands-free gates and timing points generally need 860-960 MHz UHF.

03

Confirm data and encoding

Tell us whether you need UID lists, NDEF records, sector data, printed serials or QR matching, and we will encode before shipment.
