When your access control setup spans older proximity readers alongside newer MIFARE infrastructure, running two separate card types is the kind of friction that quietly adds up — lost cards, confused staff, doubled inventory. The MIFARE Classic® 1K NXP EV1 & EM4200 Dual Technology cards are designed precisely for that situation. A single card carries both the NXP EV1 MIFARE Classic 1K chip and the EM4200 proximity chip, so one credential works across both reader generations without compromise.

Each card conforms to the standard CR80 credit card format (86mm × 54mm) with 1K byte of MIFARE memory — enough for typical access control and identification applications. Issued in packs of 100, they suit organisations managing a meaningful number of cardholders, whether you're rolling out a new system, refreshing existing credentials, or maintaining stock for ongoing issuance.

The kind of card procurement decision that tends to get made once and then forgotten about — because the cards simply do what they're supposed to do, across every reader on site.
