The MIFARE DESFire 2K NXP EV1 Cards are contactless smart cards built around NXP's EV1 chip — the kind of card that suits organisations running access control, time and attendance, or multi-application ID schemes where reliability and standards compliance matter. Each card carries 2K bytes of EEPROM memory, enough to handle multiple applications on a single credential without compromise.

Operating at 13.56 MHz with data transfer speeds of up to 848 Kbits/s, transactions are quick and consistent — important when you're processing staff or visitors at a gate or door rather than waiting on a slow read. Full compliance across all four levels of ISO/IEC 14443 A means these cards will integrate cleanly with readers and systems built to that standard, which covers the vast majority of professional access control infrastructure.

Supplied in packs of 100, the AC-MF-DS2KX is a practical choice for initial deployments or ongoing card issuance programmes. If you're specifying contactless credentials for a site in Ireland or across the EU, DESFire EV1 remains a well-supported and widely understood format.
