Use case
Access Control Device Manufacturing
An NFC reader or door controller for commercial access control. Volume 1000 to 5000 units per batch. Each unit gets a unique credential signing key injected into the secure element during production, paired with a serial that registers with the customer key management system.
Typical BOM characteristics
- NFC or RFID front-end IC with tuned antenna
- Secure element (ATECC608 or similar)
- Microcontroller with crypto support
- Tamper-detection sensor (lid switch, accelerometer)
Test plan example
- RF antenna tuning verification
- Credential round-trip with reference test card
- Tamper-detection sensor functional test
- Secure element key injection and certificate enrollment
Box-build scope
- PCBA into vandal-resistant housing
- Tamper-detect lid wiring and verification
- Conformal coating on RF section
- Label with serial after final test
Lead-time pattern
8 weeks NPI, 4 to 5 weeks repeat batch
