## Description
Proud Tek encodes RFID cards at the factory so they arrive ready to deploy: UID databases, NDEF records, MIFARE sector data, DESFire application...

## FAQ
- Q: Can you encode RFID cards to work with our existing access control system?
  A: Yes. Provide your reader model, system brand, and either a sample encoded card or an encoding specification document. We can reverse-engineer the format from a sample card and replicate it across your order, and we have experience with HID, Gallagher, Salto, Keri, Honeywell, Bosch and many other access control systems.
- Q: Is there an extra charge for RFID card encoding?
  A: Basic encoding (UID reading, NDEF URL writing, simple data programming) is included at no extra charge for orders above 1,000 cards. Complex encoding — DESFire application setup, multi-sector MIFARE encoding, hotel lock format programming — carries a small per-card fee depending on the specification, quoted upfront before production.
- Q: How do you securely handle our encryption keys and encoding data?
  A: Keys are transferred via encrypted channels (PGP-encrypted email or secure file sharing), loaded onto air-gapped encoding stations, and never stored on networked systems. After production, all key material and encoding data are securely deleted per your retention requirements — or escrowed only on your explicit instruction. NDAs and data processing agreements are available.
- Q: What data do you need from us to start an encoding job?
  A: Any of three things: an encoding specification document describing the data layout, a CSV or Excel file of the values to write (URLs, numbers, credentials), or a working sample card we can read and replicate. We confirm our interpretation of the format in writing and verify a first article before the volume run starts.
- Q: How do we verify the encoding after delivery?
  A: Every order ships with an encoding database (CSV, Excel or XML) mapping each card to its UID and encoded values, plus a functional test report on the lot. Cards are 100% read-back verified at the factory, and batch records are retained for at least seven years if a field question ever needs tracing.
