13.56 MHz HF C-tier format

A factory-fresh, rewritable Dormakaba / Kaba DK - Ultralight C 50pF — the programmable blank our compatible 13.56 MHz smart cards are encoded onto, supplied loose or pre-encoded in bulk. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible Dormakaba / Kaba DK - Ultralight C 50pF works

The Dormakaba / Kaba DK - Ultralight C 50pF is a 13.56 MHz high-frequency contactless credential read over the ISO/IEC 14443 air interface. Its data structure is Dormakaba encoding on UL-C 50pF; 3DES. When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.

Because the Dormakaba / Kaba DK - Ultralight C 50pF is a secured smart credential, it is designed so the encryption keys stay under your control. We supply compatible blank credentials built on the matching Genuine NXP MIFARE Ultralight C platform, ready for your access-control system or integrator to enrol exactly as it would credentials ordered through the original vendor's channel. You get drop-in spares and bulk stock at a fraction of OEM pricing — and because your own system writes the keys, every credential inherits your site's security.

To order, tell us the part number or format printed on your existing Dormakaba card, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.

Dormakaba / Kaba DK - Ultralight C 50pF — common questions

Is this a genuine Dormakaba card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the Dormakaba / Kaba DK - Ultralight C 50pF so it reads identically on your existing readers, but it is not an Dormakaba-branded product. Security ID Systems is independent and not affiliated with Dormakaba; your access-control panel accepts the credential exactly the same way.

How do you supply a replacement for my secured Dormakaba smart card?

The Dormakaba / Kaba DK - Ultralight C 50pF is a secured smart credential, so the encryption keys stay under your control. We supply compatible blank credentials on the matching Genuine NXP MIFARE Ultralight C platform that your own system or integrator enrols — exactly like ordering blanks through the original vendor's channel, at a fraction of the cost. Because your system writes the keys, the credential inherits your site's security.

What frequency and format is the Dormakaba / Kaba DK - Ultralight C 50pF?

It operates on 13.56 MHz HF, using dormakaba encoding on ul-c 50pf; 3des. Matching that exact frequency and data structure is what makes a compatible credential work — a card on the wrong band or bit length simply will not read.
