The MIFARE DESFire 4K NXP EV3 Cards are contactless smart cards built around genuine NXP chips, operating at 13.56 MHz — the frequency that forms the backbone of most modern access control and identity infrastructure. Each card carries 4 Kbytes of memory, which gives you meaningful headroom for multi-application deployments: access control, identity verification, and micropayment systems can all share the same card without compromise.

Supplied in the standard CR80 format (86mm x 54mm), these are the kind of cards that slot into existing workflows without adjustment — the same dimensions as a credit card, the same form factor your readers and printers already expect. The EV3 generation from NXP represents the current production standard, so you're specifying components with a clear future in active deployment rather than legacy stock.

Sold in packs of 100, these cards suit organisations that need reliable, consistent smart card stock — whether you're issuing staff credentials, managing building access, or running a campus payment scheme. Authentic NXP chips mean you're working with the real specification, not a compatible approximation.
