RAIN RFID Ecosystem
NXP is driving the adoption of UHF RFID technology by serving as an active member of the RAIN Alliance.
UCODE® RAIN RFID
UCODE integrated circuits (ICs) deliver highly accurate and efficient new ways to identify, locate, authenticate and engage each item or asset anywhere along its journey from production to the final sale and beyond.
With its high read sensitivity, fast programming capabilities and security features, UCODE ICs are being used across various industries including retail, supply chain and logistics, airlines and airports, manufacturing and automotive.
