Monza 4 QT Technology


Control What the World Sees

Impinj's QT® technology provides a unique ability on select Monza tag chips to maintain two data profiles to support protection of business-sensitive data and consumer privacy. With QT technology, tag owners can use a private data profile to store confidential data, while a public data profile holds less sensitive information. The ability to switch between these two profiles is protected by the tag's access password, physical distance from a reader antenna via a short range mode, or both.


Private/Public Profiles

In the Private Data Profile, users have access to several data/memory blocks: a private EPC memory, a serial number, an alternate product identifier, a serialized tag identifier (STID), and User memory. The Public Data Profile only contains the IC model information and the alternate product identifier. When a tag is switched to the Public Data Profile, all other data appears to be non-existent.



Short Range Mode—Physical Distance Protection

QT technology’s Short-Range Mode adds a layer of physical protection to a user’s private data by reducing the tag’s read range to less than one-tenth of its normal range. So while a reader can always singulate the tag and read its currently exposed identifier (EPC or alternate product identifier) from normal range, any attempts to access the Private Data Profile from a distance will cause the tag to lose power and drop out of its dialog with the reader. The short-range feature ensures that protected information is not readable unless the tag is very close to a reader antenna.
