Security Features
While simple, the EV1 adds improved security over the original Ultralight:
- 32-bit One-Time Programmable (OTP) Area
- For write-once data (e.g., marking the ticket as "used").
- Write Protection
- Lock bits can permanently protect memory pages from further writes.
- 3-Pass Authentication (optional)
- Supports a 16-bit password protection scheme (activated via configuration) to restrict read/write access.
- Anti-Tearing Mechanism
- Helps maintain data integrity if the card is removed during a write.
Memory Layout (Simplified)
Page | Content |
0–1 | Serial Number / UID (7 bytes) |
2 | Internal / Lock Bits |
3 | OTP Area (32 bits, e.g., for ticket validation) |
4–15 | User Memory (48 bytes, main data storage) |
Additional | Configuration, authentication, lock bits |
Typical Applications
Due to its low cost and NFC compatibility, it is widely used in:
- Disposable Transit Tickets(single-use or few-use tickets)
- Event & Festival Access Wristbands
- Product Authentication / NFC Tags
- Loyalty Cards & Coupons
- Hotel Keycards(limited-stay)
- NFC Forum Type 2 Tagapplications (e.g., smartphone interaction)
Comparison with MIFARE Ultralight C
