NFC (Near Field Communication) is an innovative innovation in customer and industrial components of the IoT (Internet of Things). It gives a unique digital identity to each item and could guarantee the genuineness and integrity of items across their lifespan. Using the NTAG 224 DNA and NTAG 223 DNA line, NXP sets another connectivity level – facilitating an ‘Internet of Everything’, where companies and their customers could utilise Near Field Communication innovation in an entirely passive mode to sense, verify, monitor and protect using new effective methods. The NTAG 22x DNA line of tag microchips is targeted at consumers who require high-volume labelling solutions at a reasonable price with advanced security and functionalities. This line is powered by SUN (Secure Unique NFC) message verification with Advanced Encryption Standard cryptography and awareness of status utilising capacitance. The item’s application space is almost limitless because it could be utilised as a verification tag, an anti-tampering tag, or a simple detecting tag that does not require a battery, extending the scope of the trusted Internet of Things.
Key Features
Some of the most critical features of NTAG 223/224 DNA are:
- Complete NFC interoperability – ISO/IEC (International Organization for Standardization/International Electrotechnical Commission) 14443-A communication, NFC Forum Type 2 tag.
- Advanced Encryption Standard-128 cryptography and CC (Common Criteria) EAL (Evaluation Assurance Level) 3+ certification.
- It has 144 bytes of user memory (NTAG 223 DNA) or 208 bytes of user memory (NTAG 224 DNA).
- Secure Unique NFC message verification for advanced data protection inside NDEF (NFC) read operations.
- Customisable originality mark (48-byte that depends on Elliptical Curve Cryptography) to verify the tag’s origin.
- Conductive tamper security systems (NTAG 22x DNA Status Detect).
- 7-byte Unique Identification.
- On-chip manufacturing of product Uniform Resource Locators with ASCII (American Standard Code for Information Interchange) mirrors (Unique Identification, status of the tamper, counter, CMAC (Cipher-based Message Authentication Code)).
- They are programmed Near Field Communication tap counter.
- It has 50 pF input capacitance for a small antenna design.
- Capacitive detecting interface to external capacitors to measure the changes in atmospheric conditions, such as air pressure, humidity level, etc.
Key Benefits
Some of the main benefits of NTAG 223/224 DNA are:
- Cryptographically protected message verification is available for any standard NFC smartphone.
- Verification in close real-time for convenient consumer experiences.
- It is cost-effective, simple to implement and sustainable.
- It has advanced tamper detection, utilising capacitance (NTAG 22x DNA StatudDetect).
- Capability to sense explicit conditions without requiring a battery.
Key Applications
A few main applications of NTAG 223/224 DNA are:
- Secure verification – It helps to improve brand security, SC (Supply Chain) control and perceivability and advance anti-counterfeiting.
- Next-Gen User Interactions – Hyper-customized advertising campaigns, messaging pre or post sale and status-aware messaging.
- Protecting the integrity of products – Detecting leaks, sealing securely, anti-tampering, protection from refill fraud and detecting specific conditions, such as moisture level in the atmosphere.
