...an encrypted message or hash that only your server can validate. ✅ Solution: Use NTAG 424 DNA for AES-128 encryption & dynamic authentication. ❌ Risk: More expensive than regular NFC tags but extremely secure. 3. Implement Server-Side Authentication (Tokenized URLs) Instead of embedding a static URL on the NFC tag, generate a unique, temporary token for each scan. The URL could look like this: arduino Copy Edit The token is validated server-side and can: Expire after one use (prevents replay attacks). Be tied to the NFC chip UID (ensures it’s the original tag). Include a cryptographic signature (HMAC or JWT) to prevent tampering. ✅ Solution: Use JWT (JSON Web Token) or HMAC signatures to validate scans. ❌ Risk: Requires a server backend to generate
