UCODE® DNA: UHF Tag IC for Secure Authentication
2023-10-28 View：
The secure UCODE DNA RAIN RFID (UHF) tag IC supports use cases that require long read ranges of up to 15 meters. The IC combines advanced contactless performance with cryptographic security and enables a variety of Smart City applications, such as asset tagging, automatic vehicle identification, access control, and supply chain management.
The security of the chip is based on a 128-bit AES key which is stored in the IC hardware and performs cryptographic authentication checks. The UCODE DNA IC is designed in compliance with standards for worldwide interoperability, namely the GS1™ UHF RFID Gen2 v2.0 (Annex N, Tag Alteration (Authenticate)), and ISO/IEC 29167-10 for proof of origin based on AES (Advanced Encryption Standard).
