Frequently Asked Questions
What is the read range of Impinj Monza 4 RFID chips?
The Monza 4 series delivers extended read ranges depending on antenna design and reader power, typically achieving several meters in optimal conditions. TagFocus technology improves sensitivity in dense reader environments where multiple readers are present.
How much memory does the Impinj Monza 4 have?
The Monza 4 series includes 128 bits of EPC memory, 512 bits of user memory, and 64 bits of TID memory. Variants like Monza 4D, 4E, and 4i offer different memory configurations within the family.
What is FastID on Monza 4 chips?
FastID is a rapid singulation feature that enables high-speed reading of multiple tags simultaneously. This allows for faster inventory counts and improved throughput in applications requiring quick tag reads.
What is the difference between Monza 4QT and standard Monza 4?
Monza 4QT includes QT (Quiet) technology with public and private memory modes, allowing portions of memory to be hidden or revealed based on application needs. Standard Monza 4 variants (4D/4E/4i) focus on different memory sizes without the public/private mode functionality.
Does Impinj Monza 4 support ISO 18000-63?
Yes, the Monza 4 series is fully compliant with EPC Class 1 Gen 2 Version 2, which corresponds to the ISO/IEC 18000-63 standard for UHF RFID air interface protocol.
What security features does Monza 4 offer?
Monza 4 includes 32-bit access and kill passwords for protecting tag data and permanently disabling tags. It also features locked TID memory for authentication, AutoTune for consistent performance, and Self-Adjust for adapting to varying RF environments.
