Chip technical brief
MIFARE DESFire EV2 4K (NXP MF3DH** family) offers originality checking, Transaction MAC, Proximity Check and Virtual Card Architecture, with Common Criteria EAL5+ certification for the IC. NXP recommends EV3 for new designs, while the status of EV2 ordering codes varies. For an existing EV2 program, confirm the exact approved part, traceable supply, reader configuration and key plan before a repeat order; do not assume the chip alone makes an access or payment system compatible.
Buyer one-liner
Existing EV2 programs: verify the exact part and supply; evaluate EV3 for new designs.
Typical use cases
- ▸New transit deployments
- ▸Multi-app campus credentials
- ▸Hotel chain unified credentials
- ▸Government employee badges
- ▸High-security building access
Reader requirements to validate
Confirm the exact reader model, firmware, antenna, supported protocol and application or credential data with the system owner. Test the finished sample on the installed setup; a chip datasheet or shared frequency does not establish compatibility.
Card construction and approval
A contactless card combines a selected chip and antenna with a card body. Start with the system-approved chip, data format and reader, then confirm face dimensions, finished thickness, material, print method and any magnetic-stripe or contact-chip option. Material names do not establish heat resistance, printer fit, recyclability or lock compatibility. For custom artwork and numbering, agree a proof and an encoded sample before production. The card MOQ in the company policy is a baseline; quantities, packing, chip availability and production timing belong in the configuration-specific quotation.
Typical sizes
- • ID-1 / CR-80 face size (85.6 × 54 mm); approve thickness
- • Other card sizes and shapes subject to drawing and tooling review
Materials
- • PVC
- • PETG
- • ABS
- • Wood or bamboo
- • Coated paper
Document scope to verify
Request current documents for the exact finished article, materials and destination. A form-factor name does not establish a certification or IP rating.
Why source MIFARE DESFire EV2 4K cards from RFIDAK
DESFire EV2 4K may fit an approved multi-application credential when the actual application layout fits its usable memory and the installed system supports the chosen security configuration. Compare the proposed card body, thickness, finish and print method with the issuer equipment and intended handling conditions. If a different body material is proposed, verify its availability and mechanical fit separately. Cryptographic chip features do not by themselves establish an end-to-end secure deployment; the issuer must validate keys, readers, software and enrollment.
Buyer snapshot
Enterprise, campus and hospitality system owners comparing approved DESFire configurations. The issuer or integrator should supply the application and reader requirements before the card body, chip and personalization are quoted.
Planning examples
Illustrative evaluation plans, not reported customer results.
Example 1
Illustrative hospitality plan (not a customer case): a property operator asks its lock and payment providers whether one approved card profile can support both workflows. It tests the exact installed devices and keeps guest and staff permissions separate before signing off on artwork.
Example 2
Illustrative office pilot (not a customer case): an integrator records current card and reader versions, then tests a newly issued credential for enrollment, allowed and denied doors, revocation and reissue. It documents any required reader or software change before ordering replacement stock.
Compare with other cards
Compare chip-level differences for the same form factor. Check the exact reader, credential format, finished construction and available samples before selecting a configuration.

Frequently asked — MIFARE DESFire EV2 4K cards
What is the minimum order quantity for MIFARE DESFire EV2 4K cards?▾
MOQ guidance for this format: 500 pieces baseline; confirm the selected card. Pilot size and unit price depend on chip availability, format, encoding, artwork and quantity; request a written quote for the exact specification.
How should I check reader compatibility with MIFARE DESFire EV2 4K cards?▾
Check the exact installed reader and controller model, firmware, credential profile and application data requirements. A frequency or protocol match alone does not prove compatibility. Have the system owner test a representative finished sample before authorizing production.
Can RFIDAK pre-encode MIFARE DESFire EV2 4K cards to our specification?▾
Writable EPC, NDEF or user-memory content may be encoded to an approved specification, depending on the chip and access rights. Factory-programmed UIDs normally cannot be changed. Secure credential provisioning needs an agreed key-custody process; never submit secret keys in a public inquiry form. Confirm feasibility and price for the exact data format.
What lead time should I plan for MIFARE DESFire EV2 4K cards to major export markets?▾
Confirm a production-ready date after the specification and sample are approved, then obtain a separate freight and import timeline for the destination. Ask for dated milestones in the project quote rather than relying on a form-factor average.
Which documents apply to MIFARE DESFire EV2 4K cards?▾
Document scope depends on the exact material, chip, reader and destination market. Ask RFIDAK to identify the applicable certificate or test report for the quoted SKU; a company certificate or another product's report does not automatically certify this configuration.
