Does Any Software Update a Database Based on RFID Location Data?

This is what all RFID software does. Each time a tag is interrogated, the reader sends the tag ID number, as well as the reader ID, sometimes an antenna ID, and the date and time at which the tag was read, to middleware or directly to a back-end database. Since the reader ID is associated with a location (at least if the deployment was properly carried out), that location is noted in the database.
