NXP Product: NTAG® 424 DNA Chip

NTAG® 424 DNA Chip

424 DNA TagTamper – Advanced security and privacy for trusted IoT applications

NTAG 424 DNA sets a new standard in secure NFC and IoT applications. The new chip generation offers state-of-the-art features for security and privacy protection, on attack-resistant certified silicon.

The NTAG 424 DNA is architected to provide AES-128 cryptographic operation, new SUN authentication mechanism upon each read-out by an NFC enabled mobile device, as well as sensitive data protection with crypto-secure access permissions. This enables advanced product and content protection, plus secured and unique user experiences served in real-time.

The NTAG 424 DNA TagTamper tags go further and facilitate even more customized engagements by serving up status-aware, relevant consumer messages once the tag’s seal on a label or container has been broken.

Track & Trace Solutions for the Food Supply Chain

Track & Trace Solutions for the Food Supply Chain! The food supply chain is a complex and multifaceted system that spans from farmers to consumers. Numerous challenges can arise during a product’s journey, including lack of product traceability, food safety, and inventory management. One solution to these challenges is the use of UCODE based tags from NXP Semiconductors. These tags enable real-time visibility of products as they move through the supply chain, allowing for better inventory tracking, enhanced supply chain efficiency, and improved food safety. By tagging food items with UCODE based tags, suppliers can monitor location and store important information (lot number, expiry date), ensuring that products remain safe and fresh until the point of sale. Skyrocketing food prices and sustainability concerns move increasing numbers of brands and retailers to adopt RAIN RFID solutions.
