13.56 MHz(HF) + UHF hybrid dual-frequency ISO cards

About the DUAL FREQUENCY RFID CARDS HF-UHF Card

Where a secure door credential and a long-range identifier are both needed, the dual frequency HF-UHF RFID card carries the two on a single ISO7816 badge. Its 13.56 MHz side runs MIFARE Classic EV1 or DESFire EV1 and EV2 for encrypted proximity identification at doors, lifts and cashless terminals, while the UHF EPC Gen2 side answers a gate or portal reader from a distance for long-distance identification. For an organisation already standardised on Mifare, this is the cleanest way to add UHF coverage: the HF credential and its key structure stay untouched, and the UHF number is simply added to the card the staff already carry.

Key specifications

Best-fit applications

• Corporate towers keeping DESFire on doors and lifts while a UHF lobby portal counts movement
• Hospital staff badges that open HF-controlled rooms and register at UHF ward entry points
• Manufacturing plants doing UHF muster roll-call at assembly points on the existing Mifare badge
• Data centres and labs where cabinet access stays encrypted HF but room entry is read hands-free
• Conference and exhibition badges combining HF session check-in with UHF hall counting
• Retail head offices pairing HF cashless canteen with UHF stockroom door reads

Mounting, encoding and reading notes

Two antennas share one card body, so encode in two passes: MIFARE sectors or DESFire applications on an HF encoder with your keys, then the EPC memory on a UHF desktop encoder. Ask for both to be delivered pre-matched so one record covers both numbers. In use, the HF side needs the card within a few centimetres of the pad, while the UHF side wants the card clear of the body and hands, held face-on to the portal antenna. Print, punch and laminate before encoding, and avoid metal cardholders.

Why buy from Identium

Identium builds RFID in New Delhi and has been BIS and WPC certified since its 2015 start, so Indian customers deal with the manufacturer directly and exporters get ETSI-compatible product. Custom encoding, key management, artwork and numbering are in house, bulk and OEM pricing is quoted on request, and free samples let you prove the card on both reader types.

Frequently asked questions

What is a dual frequency HF UHF RFID card?

A dual frequency RFID card is an ISO 7816 format badge that combines a 13.56 MHz HF chip and a UHF EPC Class 1 Gen 2 chip in a single card. The HF side handles proximity identification while the UHF side allows long distance identification from the same credential.

Why use a dual frequency RFID card for access control in India?

Dual frequency HF and UHF cards simplify migration of an existing access control system in India, because one badge works with the installed 13.56 MHz readers and with new long range UHF readers at gates and parking lanes. UHF in India runs on the WPC approved 865 to 867 MHz band.

Which chip technologies do these dual frequency cards support?

These dual frequency RFID cards support 13.56 MHz technologies including Mifare Classic EV1, DESFire EV1 and DESFire EV2, combined with UHF EPC Class 1 Gen 2 for long distance reading. The card follows the standard ISO 7816 format used for staff, student and visitor badges.

Can dual frequency RFID cards be printed and ordered in bulk in India?

Yes, dual frequency HF and UHF RFID cards can be supplied with custom printing and encoding and in bulk quantities by India RFID Store, a BIS and WPC certified Indian manufacturer. Card pricing depends on quantity and chip combination, so check the listed price or request a bulk quote.
