Global Positioning System (GPS) monitoring device

BLUtag (U.S. Patent RE 39,909 and RE 38,838), launched in 2005, is the original one-piece GPS monitoring device. Now in its fifth generation, no other one-piece GPS monitoring has been in use as long as BLUtag. The lightweight and inconspicuous device attaches around an enrollee’s ankle and remains there until the supervising agent removes it.


  • One battery charge powers the device for 48+ hours
  • Detects and reports four types of tampering: strap, case, GPS signal jamming and shielding
  • Enhanced Secondary Location Technology engages when not receiving GPS signals: uses data from cellular phone towers, including the signal strength, to provide enhanced location confirmation
  • Battery permanently sealed in hypoallergenic, industrial-grade plastic case eliminating:
    • incorrect installation of a new battery
    • liquids seeping into the case (not closing the case securely)
    • lost or outdated replacement batteries
  • Monitors enrollees in active, passive or hybrid modes without changing equipment
  • Receives one GPS location point every minute regardless of violation status
  • Supervising agents can immediately locate any enrollee through Location Requests
  • Built-in memory stores up to 10 days of monitoring data
  • All zone information is stored in the built-in memory
  • Communicates, or reports into, VeriTracks using nationwide cellular phone service
  • Lifetime warranty and no questions-asked return policy
  • Works with BLUhome and BLUbox to expand its monitoring capability
  • Also works with Stalker Alert

One GPS Location Point Per Minute

BLUtag receives one GPS location point per minute, regardless of violation status. This industry standard helps increase the level of public safety and enrollee accountability because it does not create gaps of time where the enrollee’s location is unknown.

For example, if an enrollee travels in a car at 30 mph and the GPS monitoring device receives one location point every five minutes. The enrollee would travel 2.5 miles between location points, which provides plenty of opportunity to enter and leave a prohibited area. The same enrollee monitored with BLUtag would travel only 0.5 miles between location points, creating a higher level of enrollee accountability.
