About this product

Works with access-control, turnstile, parking, and cafeteria systems. Proximity only verifies identity; Mifare can also store balance and authorization data on the card itself. NFC cards run on the same 13.56 MHz band and can be read by a smartphone without a separate reader, which is why they're preferred for uses like digital business cards and menus. All three can be produced with edge-to-edge printing to match your corporate identity.

Frequently asked questions

Frequently asked questions about RFID Cards. If you don't find your question here, you can call us.

What's the difference between Proximity and Mifare?

Proximity (125 kHz) only reads out the card's identity — no data is stored on it. Mifare (13.56 MHz) has encrypted memory, so balance, authorization, and sector data can be held on the card itself. Cafeteria and balance-based systems need Mifare.

Will it work with my existing turnstile system?

Tell us your system's frequency and chip type and we'll pick a compatible card. If you're not sure, send us a sample of your current card — we'll read it and produce a match.

Can a contactless card be printed on?

Yes, edge-to-edge printing is available. The card number or UID can also be printed on the card, so a lost card can be matched up physically as well.

What is an NFC card used for?

An NFC card runs on the 13.56 MHz band and can be tapped against a smartphone without a separate reader. Content like a digital business card, a menu, a promotion page, or WiFi details can be loaded onto the card and shared with a single tap.
