Monza^® X UHF RFID Chips

Impinj’s Monza® X-2K Dura and Monza® X-8K Dura UHF RFID chips enable users to communicate wirelessly with the processor inside electronic devices using standard UHF Gen 2 RFID readers, unlocking many new benefits for consumer electronics manufacturers, retailers and end users. Embedded directly into the circuit board of an electronic device, Monza X chips link to the device’s processor through a standard I2C bus, enabling the processor or a UHF reader to read and write the Monza X chip memory even when the electronic device is powered off. By enabling electronic devices to communicate with RFID readers, Monza X chips deliver a wide range of extended capabilities such as theft deterrence in the supply chain and wireless device configuration at point of sale and beyond.
