Detailed product information
Offering Security, Sensing and Tamper Protection, While Enabling the Next Level of Trusted Applications at Scale
With the new NTAG 223 DNA and NTAG 224 DNA line, NXP establishes a new level of connectivity – enabling an ‘Internet of Everything’ where businesses and their consumers can use NFC technology in fully passive mode to authenticate, protect, sense, and monitor in powerful new ways.
The NTAG 22x DNA line of tag ICs is targeted at customers who need high-volume tagging solutions at an affordable cost, without sacrificing advanced security and functionality.
The NTAG 22x DNA line is powered by SUN (Secure Unique NFC) message authentication with AES cryptography and status awareness using conductance or capacitance. The product’s application space is virtually unlimited, since it can be used as an authentication tag, an anti-tampering tag, or a simple battery-free sensing tag, expanding the reach of smart, trusted IoT objects.
