Genuine NXP® MIFARE® Classic 1K chip technology in a printable, CR80-size white PVC card for compatible 13.56 MHz identification and access control systems.
Important Information About Optional Imprinted Numbers
If opting for an imprinted number, the card’s factory UID is printed in reversed-byte decimal format. Depending on your access control system and reader configuration, the printed number may differ from the number displayed by your software.
Please verify your system’s numbering requirements before purchasing. If you require a specific UID format, contact us prior to ordering.
Example: One UID, Different Number Formats
| Interpretation | Number |
|---|---|
| UID hexadecimal | C0FDA91B |
| Standard decimal | 3237849371 |
| Reversed-byte decimal (imprinted format) | 464125376 |
Example shown for illustration only. Actual card UIDs and imprinted numbers will vary.

Confirm System Compatibility Before Ordering
These cards are intended for systems that support MIFARE Classic 1K credentials. A reader’s 13.56 MHz operating frequency alone does not confirm compatibility. Verify the required credential technology, UID interpretation, and any application-specific encoding or security keys with your system provider.
Selecting an imprinted number adds a visible representation of the factory UID; it does not change the UID or configure the card for your access control system. Before slot punching, confirm the approved punch location to avoid damaging the internal antenna or chip.
