Proximity (125 kHz), 13.56 MHz RFID and NFC cards: RFID card types that are unprinted or printed in full colour on one or both sides, numbered and personalised with names.
An RFID card is a PVC card with a built-in antenna and chip that is read contactlessly when held near a reader. It is produced in credit card size (ISO CR80, 85.6 × 54 mm) and carries identity or authorisation in systems such as turnstiles, doors, car parks, staff attendance tracking, hotel locks and canteens. The chip's frequency determines which system the card will work with; that is why choosing an RFID card starts with choosing the chip.
| Card | Frequency | Chip / memory | Use |
|---|---|---|---|
| Proximity card | 125 kHz | TK4100 (EM-compatible), read-only number | Turnstile, door, time & attendance, car park |
| 13.56 MHz RFID card | 13.56 MHz | ISO/IEC 14443 A, Fudan chip, 1K byte memory | Hotel lock, canteen, campus card |
| NFC card | 13.56 MHz | Equivalent NFC chip (not an NXP product) | Digital business card, menu, review card |
A 125 kHz reader does not read a 13.56 MHz card, and a 13.56 MHz reader does not read a 125 kHz card. If you are buying cards for an existing system, check the reader's frequency and the card type before ordering; details are in the Difference between 125 kHz and 13.56 MHz cards, What is a MIFARE® card?, What is NTAG213? and RFID card and reader compatibility guides.
RFID cards are produced unprinted or with full-colour printing on one or both sides. A variable data option is available for a different name, number or QR code on each card; the unit price decreases with quantity tier. You can order staff cards together with a lanyard in the same design. If you need a chipless card, see PVC plastic card, and for large-format event cards see ID badge . We explain how RFID technology works in the What is an RFID card guide.
