NT4H2421G0DA8/02J

NT4H2421G0DA8/02J is a NTAG 424 DNA–secure NFC T4T-compliant IC. The NTAG 424 DNA (NT4H2421Gx) sets a new standard in secure NFC and IoT applications, introducing a new NTAG DNA chip generation with state-of-the-art features for security and privacy protection. It comes with AES-128 cryptographic operation and a new Secure Unique NFC (SUN) Message feature to generate tap-unique data authentication upon each read-out by an NFC-enabled mobile device. This enables the most advanced product and content protection, plus secured exclusive user experiences served in real time. Typical applications include advanced anti-counterfeiting, secured exclusive user experiences, secured sensitive data applications, protected monetary offers, document authentication, secure authentication and configuration of closed-loop devices, verified physical visitor presence, and secure log-in credentials.
