Metal RFID Card

860–960 MHz

UHF Metal RFID Cards

UHF metal RFID cards operate between 860 and 960 MHz under EPC Gen2 (ISO/IEC 18000-63) — the band used where reading needs distance rather than a deliberate tap. Metal is the hardest environment UHF works in: an ordinary UHF inlay laminated to a metal face can lose most of its range, so these cards use on-metal antenna construction, and honest range expectations are set by testing rather than by the inlay datasheet.

Expect metal to cost range — then measure what is left.

Free-air range figures on inlay datasheets do not survive a metal card body. Orientation, reader power, antenna position, and nearby materials all move the result. A UHF metal project therefore starts from the real read scenario — gate width, mounting, direction of travel — and is approved on measured performance in that setup, not on a theoretical number.

Best uses

  • Selected long-range identification, EPC-style data, asset flow, event experiments, and product authentication.
  • Metal card programs that can validate a finished encoded sample on the target reader
  • Projects that need print, serial, QR, packaging, and data handling reconciled in one approved brief

Frequently asked questions

When does a metal card genuinely need UHF?

When reading must happen at a distance or in bulk — gates, asset flows, vehicle-adjacent identification — under EPC Gen2 infrastructure. For tap-range use, HF and NFC are the correct band; UHF is chosen for range, not prestige.

Can a phone read a UHF metal card?

No. Smartphone NFC is 13.56 MHz; UHF runs at 860–960 MHz and requires a dedicated UHF reader or scanner. Programs that need both add a printed QR zone or a dual-technology plan.

How far does a UHF metal card read?

It depends on the on-metal antenna build, reader power, orientation, and surroundings — metal costs range, and the honest figure comes from testing the finished card in the real scenario. Range is approved by measurement, not quoted from an inlay datasheet.
