Passive Tracking in an Office Environment

The latest RFID technology - called Ultra-High Frequency, or UHF - started gaining support in 2003.  Wal-Mart announced their RFID Initiative in July 2003, and similar announcements followed from Kroger, Tesco, Boeing, and the US Department of Defense. Whole new industries like Pharmaceutical and Asset Management would join the RFID market, 2nd and 3rd tier companies in the Retail and Grocers industries would join.

FileTrail introduced the Passive Tracking concept for the office. This overcame the limitation of bar coding, primarily the difficulty of getting staff to scan bar codes every time a file moves.  With RFID, files are checked out and transferred automatically as they move from office-to-office.  Files virtually tell the system where they are, saving time by eliminating searches for files. Another benefit is the increased efficiency of universal access to an online inventory of files, boxes, and documents.

The unique capabilities of UHF RFID are the key to Passive Tracking.  Long distance reading means that placement of hardware can be far less invasive than previous RFID technologies.  RFID sensors can be placed in drop-ceilings completely out of sight.  They can also be mounted under desks, keeping the employees work area surface completely clear, automatically updating the location of the files inFileTrail.  Any employee needing a file can quickly locate it using the FileTrail Search screen.
