RFID Dual Frequency Card – UHF U8 9662 + ID-125KHz EM4100/TK4100 (Fixed ID)

Description

This writable UHF + Fixed ID-125KHz Combo RFID Card combines an NXP UCODE 8 chip (EPCglobal Gen 2v2, ISO 18000-63 compliant) for long-range UHF communication and a 125KHz TK4100 chip for low-frequency identification with a fixed, read-only ID number. The UHF component enables efficient tracking, asset management, parking and bulk inventory operations over extended distances, while the TK4100 chip ensures consistent identification for legacy systems such as access control, time attendance, or parking.

This dual-frequency card is ideal for environments where both modern EPC-based UHF systems and traditional 125KHz proximity systems are used in parallel. The UHF side supports writable EPC memory and integration with advanced RFID infrastructure, while the TK4100 chip delivers stable compatibility with most 125KHz readers using EM4100/TK4100 protocol.

Dual Chip Integration:

UHF + ID 125KHz chip in one card supports both long-range tracking and short-range scanning.

UHF Chip – NXP U8:

  • Compliant with EPC Gen2 / ISO18000-6C
  • Up to 10m read range (depending on reader)
  • 128 bits (user writable)

ID Chip – EM4100/TK4100:

  • 125KHz low-frequency RFID chip
  • Compatible with EM4100 / TK4100 protocol
  • 5-byte fixed ID (read-only, non-writable)
