Reliable product authentication and improved customer experience are made possible by NFC inlays and tags nowadays. The high degree of security provided by NFC tags eliminates counterfeiting and creates digital networks that are unrivaled in terms of confidence and value.
Secure NFC inlays and tags use cryptographic algorithms to provide real-time product verification, leading to higher security in many implementations. Brand owners and manufacturers of branded goods may transform their products into highly protected digital channels by embedding NFC tags into physical products or packaging. This can provide unrivaled value over the product’s life cycle, from manufacturing to delivery.
Consumers can use their NFC-enabled smartphone to verify a product digitally, and businesses can verify the authenticity of returns. While using a “cloud”-based service, a product’s geographic location may also be determined. This NFC technology isn’t restricted to a plastic card’s form factor. Other printed goods, such as NFC labels, NFC tags, and NFC key fobs, could also be incorporated with the chip.
What makes NTAG 424 DNA unique?
A hidden AES-128 symmetric key is kept in secure memory space in NXP’s NTAG 424 DNA. When a tag is read, the counter on the tag rises by one. The tag then produces a cryptographically stable identifier by encoding the UID (or EPC) and counter simultaneously. The signature is then added to the Digital Link, and the reader is given the entire URL. The enc parameter includes the UID and counter encoded for the NTAG 424 DNA.
How is NTAG 424 DNA more secure?
A protected NFC tag can only prevent the copying of a tag. An NFC tag may still be used to store a redirection URL by a counterfeiter. The gateway creates a new one-time password each time to prevent a reconfiguration from being repeated, which it authenticates with its encryption key.
The NTAG 424 DNA provides the best requirements for your IoT application thanks to its various protection features such as secured UID, randomized ID, and fast speed of 848 kbit/sec.
Once the tag’s seal on a package or item has been breached, the NTAG 424 DNA TagTamper tags go even further and encourage even more personalized engagements by serving up status-based, related customer messages.
NXP NTAG 424 DNA has advanced protection and privacy features.
NXP’s NTAG 424 DNA ICs provide real-time tag and message authorization using AES-128 encryption on robust silicon and are compatible with all NFC-enabled devices like smartphones. The Secure Unique NFC (SUN) authentication function allows tags and servers to share data securely, accountable, and confidential. This maximum-security IC option provides strengthening privacy features and personal data stored on the chip, all of which is secured by a complex three-pass mutual authentication system.
The development of these IC options improves the business case for safe product authentication and improved customer interaction in a wide range of applications, including a wide range of branded goods susceptible to counterfeiting.
