NFC, secure authentication, anti-tamper & sensing into a single battery-free chip


NXP Semiconductors NTAG 22x DNA combines NFC, secure authentication, anti-tamper & sensing into a single battery-free chip. It's unique in the sense that it can sense moisture, pressure or fill level, upon a simple tag readout.


Applications:

1. Brand protection and anti-counterfeiting

2. Anti-tampering and refill fraud protection

3. Document authentication

4. Augmented content experiences, such as status-aware or one-time messages


"The NTAG 22x DNA ICs introduce a new level of status awareness, turning the tag into a simple battery-less sensing device to detect a physical product’s first opening status or a change in its specific ambient condition. This helps manufacturers protect product integrity, whilst enabling a new level of intelligence to assure product quality or correct handling.”


NXP NTAG 22x DNA key features:

1. Certified Security: It is Common Criteria EAL3+ certified, and features a powerful, cryptographically secure authentication

2. Dual-Mode Tamper Detection: It also includes configurable conductive or capacitive tamper detection

3. Condition Monitoring: It can be used as a passive sensing device to detect environmental changes.
