Quick spec — MIFARE DESFire EV2 4K Card
Chip technical brief
MIFARE DESFire EV2 4K (NXP MF3DH** family) builds on EV1 with four major additions: Originality Signature using ECDSA for chip authenticity verification (cloning protection), Transaction MAC for end-to-end transactional integrity, Proximity Check that defeats relay attacks, and Virtual Card Architecture supporting both contactless cards and handset-based dual-interface credentials. EV2 4K is now the default chip for new transit deployments, multi-application campus IDs, complex hotel chains issuing one credential for access + payment + loyalty, and government employee badges. Common Criteria EAL5+ certified.

Card manufacturing
The CR-80 card body is the ISO 7810 ID-1 standard at 85.6 × 54 × 0.84 mm and is the dominant form factor for contactless smart credentials. RFIDAK produces cards in PVC (default), PETG (recyclable), ABS (high-temperature for hotel locks that overheat), wood/bamboo (premium hospitality finish), and coated paper (single-use ticketing). The chip + antenna inlay is sandwiched between two laminated layers; full-color CMYK or 4-color silkscreen printing is applied before lamination. Common finishes include matte, gloss, magnetic stripe (HiCo or LoCo), signature panel, embossed numbering, and laser-engraved UID for tamper-evident applications. Cards ship in 200-piece cartons; standard MOQ is 1,000 cards.

Why source MIFARE DESFire EV2 4K cards from RFIDAK
DESFire EV2 4K is the most-deployed of the EV2 family, sized for projects that need 2-4 applications per card without the cost of 8K. Standard for new corporate access deployments, mid-size hotel chains issuing single-credential guest cards, and security-integrator portfolios serving 500-5,000-employee enterprises. RFIDAK ships EV2 4K cards in CR-80 PVC standard plus PETG (recyclable), ABS (high-temp hotel locks), and wood/bamboo (premium hospitality finish) variants. AES-128 + Originality Signature (ECDSA) defeat both Crypto-1 cloning and chip-replacement attacks.
Buyer snapshot
Mid-size enterprises (500-5,000 employees), hotel chains doing single-property or 2-3 property pilots, security integrators who want a balanced security-vs-cost chip, and any new project where DESFire 8K is overkill but Classic 4K is too insecure.
Anonymized project examples
Example 1
Multi-property hotel chains are the most common EV2 4K buyers: a single card SKU carrying 3 applications (room-lock access, F&B charge wallet, loyalty store) covers both employee and guest credentials, with per-property brand colorways printed from one artwork master to keep reorders simple.
Example 2
A US tech company replaced 1,200 legacy iCLASS cards with DESFire EV2 4K cards for office access, parking, and visitor escort tracking. Migration involved upgrading HID OMNIKEY 5427CK reader firmware to support DESFire-side authentication; the changeover completed in 6 weeks across 3 buildings.
