ProdataKey (PDK) Standard 26-Bit Credential Compatible Cards & Fobs
The cloud-access newcomer on an open base: ProdataKey's standard credential is a plain 26-bit Wiegand prox card (default facility code 077), which makes replacement stock for pdk.io sites refreshingly simple.

ProdataKey built a modern cloud access platform — pdk.io runs the doors from a browser — but wisely kept the entry-level credential on open 125 kHz standards: a 26-bit Wiegand card with a default facility code of 077 that installers often leave in place. For property managers that's the good kind of boring: replacement is a standard-format programming order, not a proprietary lookup. (PDK's separate higher-security 13.56 MHz line is a different animal, issued through PDK's own channel; if that's what your site runs, we'll point you there rather than sell you a prox card that won't enroll.) For the standard 26-bit fleet, we manufacture unbranded, compatible-by-specification cards, fobs, and other form factors programmed to your facility code and card-number range, verified before shipping so they enroll in pdk.io like the originals.

What credential does ProdataKey use by default?
Its standard line is a 26-bit Wiegand 125 kHz proximity credential, frequently shipped on facility code 077 unless the installer set a custom code. PDK also sells a separate higher-security 13.56 MHz smart credential; the two are not interchangeable.
Can I order PDK-compatible cards without a dealer account?
Yes, for the standard 26-bit line — it's an open-format programming order. Give us your facility code (check pdk.io or a printed card; it's often 077) and your card-number range, and we program and verify compatible stock directly.
How do I know whether my site is on the 26-bit or the 13.56 MHz PDK credential?
The card style and your pdk.io reader configuration tell you. If your readers and credentials are the higher-security smart line, those come through PDK's channel — send us a photo and we'll identify which lane you're in before you order anything.
Will compatible cards mix with our existing PDK stock?
On the standard 26-bit fleet, yes — pdk.io reads the facility code and card number regardless of who made the card, so compatible and original credentials coexist. We continue your number sequence so your pdk.io records stay orderly.
