Quick spec — MIFARE DESFire EV2 8K Card
Chip technical brief
MIFARE DESFire EV2 8K is the high-memory variant of EV2, providing 8,192 bytes EEPROM across up to 32 applications with 32 files per application. The 8 KB memory enables rich multi-application credentials: a single card carrying access (PACS file), cashless payment (closed-loop wallet file), library (book ID file), cafeteria (subsidy file), and identity (ID metadata file) without running out of file space. Standard chip for transit operators issuing tens of millions of credentials and for university chains running unified campus card programs.
Buyer one-liner
Highest-capacity DESFire EV2 with all enterprise security features; transit + complex multi-app standard.

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 8K cards from RFIDAK
DESFire EV2 8K cards are the standard credential for transit operators issuing tens of millions of multi-line tickets and for university chains running unified campus card programs that combine access, library, cafeteria, and identity into a single 8 KB partitioned credential. RFIDAK supplies pre-encoded EV2 8K cards under NDA with customer-supplied AES-128 master keys, issuer key derivation, and per-application file structures. Typical buyer profiles include LATAM transit-migration programs, GCC employee-credential projects, and US university unified campus IDs. Lead time is 12-15 working days from artwork approval; 5,000+ orders qualify for a 6-8% volume discount.
Buyer snapshot
Transit authorities consolidating multiple legacy systems, university card-program administrators, large hotel chains rolling out unified guest credentials, and government employee badge programs. Almost all DESFire 8K buyers have an in-house security or systems-integrator team that owns the AES-128 key set.
Anonymized project examples
Example 1
A LATAM-region transit authority migrated 2.3 million MIFARE Classic 1K riders to MIFARE DESFire EV2 8K over 18 months. The 8 KB chip held 6 file applications: payment wallet, route history, anti-fraud signature, age-discount certificate, journey log, and free-transfer credit. Per-card cost rose over Classic 1K, which the authority accepted as the price of closing Crypto-1 cloning exposure.
Example 2
University campus-card programs are the other classic 8K fit: a single credential typically carries 6-8 applications (building access, meal plan, library, athletic admission, parking, printing credit, vending wallet), and the 8 KB file directory leaves headroom to retire remaining legacy systems onto the same card over later academic years.
