Impinj Monza4 Tags

Details

Impinj released an updated version of the Monza4 chip with a change to the UMI bit function. This change can cause voids when attempting to print and encode using the Zebra Printers.The UMI (User Memory Indicator) bit is part of the PC (protocol control) bits, which is a portion of the EPC memory bank that tells a reader how much data is contained in the EPC. Because the UMI bit is now fixed, an attempt to rewrite it can cause the printer to void the tag.
