Protect Your Brand. Prove Authenticity. Instantly.

NFC tag ICs with rolling code cryptography and tamper detection — verified with a single smartphone tap.

Counterfeit products cost brands billions in lost revenue and erode consumer trust. Traditional anti-counterfeit measures — holograms, serial numbers, QR codes — are easily replicated. Brands need cryptographic authentication that counterfeiters cannot clone.

Dynamic Rolling Code — Changes Every Tap

Silicon Craft’s NFC authentication ICs use dynamic rolling code URLs that change with every tap. Combined with AES-128 encryption and physical tamper detection, they provide the strongest anti-counterfeit protection in a single chip. No dedicated app required — works with any NFC-enabled smartphone.

How It Works

1. Tap: Consumer taps product NFC tag with any smartphone.
2. Verify: Dynamic rolling code verified against cloud server in real-time.
3. Result: Authentication result displayed instantly. Tamper status detected automatically.
