Description
This writable UHF + HF Combo RFID Card dual chip UHF RFID card/tag combines an NXP UCODE 8 chip (EPCglobal Gen 2v2, ISO 18000-63 compliant) for long-range UHF communication, and an IC F08 chip (13.56 MHz, compatible with MIFARE® 1K) featuring a writeable memory with fixed UID for secure short-range applications. The UHF component enables efficient tracking and inventory management over long distances, while the IC F08 chip ensures stable identity for authentication and access control. The card supports storage of custom user data such as ID numbers, timestamps, or access logs, making it suitable for hybrid RFID environments requiring both long-range and secure close-range interaction.
Dual Chip Integration:
UHF + 13.56 MHz HF 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)
IC Chip – F08 (MIFARE 1K Compatible):
- 13.56 MHz ISO14443A standard
- 1KB EEPROM, 16 sectors
- 4-byte fixed UID (non-writable) for reliable access control use
Physical Specs:
- Card size: CR80 (85.6 × 54 mm)
- Material: PVC or PET
- Printable surface (optional for card printers)
