Verify the authenticity of collectibles and products protected by The NFC Mint. Hold your phone to a tag and get a clear verdict in seconds. There's no account, no setup, and no personal data collected. Every NFC Mint tag carries a secure chip that generates a fresh cryptographic code on each tap. The app validates that code against our server, and also challenges the chip itself with an NXP originality check, which confirms the chip itself is genuine and not compromised. The result is a verdict you can trust at a glance, backed cryptographically. The colored band at the top of every validation result shows Valid Tag in green, Replay Detected in gold, and Validation Disabled in red. Below it sits the full record, with product details, creation date, chip status, UID, and scan counter. Key Features • Clear tag status on every scan • Chip-level ECC originality check that web links cannot perform • Physical tamper-evident seal status for protected products • Complete product record with serial, series, UID, and scan counter • Private on-device scan log with per-tag history and CSV export (nothing leaves your phone) Made for quick checks at the counter, at shows, or before you buy. Requirements • iPhone with NFC support • Internet connection for validation
