Impinj Introduces Long-Range Read-Write Chip
Impinj, a fabless semiconductor company based in Seattle, unveiled what it claims is the longest-range read-write RFID tag. The company says tags using the Zuma chip?which is compliant with the UHF Class O Electronic Product Code specifications?can be read from 26 to 33 feet (eight to 10 meters), versus 15 to 20 feet for most UHF tags. The chip's read-write memory can also be locked for secure applications. And the chip has a "kill" feature that allows it to be rendered inoperable as a way of protecting consumer privacy. Impinj will be selling finished RFID labels using the Zuma chip. The labels available immediately for pilots and will go into commercial production in June. Impinj expects the labels to sell for less than 10 cents in large volumes.

It is more truthful.
