Bracelet tag for prisons and other detention centers.

Active RFID tag with tamper and anti-break bracelet.

The Bracelet Tag will, for the duration of its life, transmit a Radio Frequency (RF) signal at a pre-set time-interval. The Tag life is estimated at 5 years at a transmission time interval of approximately 1.5 seconds.

The lifespan of the Tag ends when the battery life is exhausted.
Battery status can be inferred by interrogating the internal Tag Age Counter Value.
The transmitted Tag data includes Customer Site Code (CSC), Tag ID, Tag Age Counter Value, Movement Alarm and Tamper Alarm status.


EXAMPLE OF USE: This tags equipped the prison of Leyland in the Netherlands:

In an effort to address prison capacity issues in a cost-effective manner, and to provide a better rehabilitative environment, the Dutch Ministry of Justice built a new pilot facility in Lelystad for low-risk offenders who had received short sentences (four months or less). The prison was equipped with a robust RFID tracking
system that allows a relatively small staff to monitor inmates in real-time as they move throughout the prison.
Inmates wear non-removable TTW-1200 RFID bracelets that provide location data via the long-range reader network to SmartTag software from U.K.-based Advanced Positioning
Systems (APS). Using the RFID bracelets, inmates log on to computer terminals located in each cell to create an individual daily schedule for work and recreation activities. Once the schedule is validated by the Ministry of Justice systems, it is transferred to the TransQuest application to authorize the
necessary access within the facility.
The system monitors inmate location and adherence to the schedule using the active RFID bracelets, and awards credits for good behavior or generates an alarm if an inmate is not within their scheduled zones for the day. As inmates accrue credits, they receive greater privileges such as extra telephone,
Internet, or television access.
Guards are alerted to schedule deviations via mobile computers integrated with the software. They also carry key fob RFID tags with built-in panic buttons in case of an emergency.
Providing real-time monitoring has helped increase the inmate-to-guard ratio, so that the facility can be operated by only six staff members. Automating inmate scheduling has reduced the cost of supervising detainees, and provided additional rehabilitative benefits by giving inmates more responsibility and control over their daily activities.
The pilot facility has been so successful that officials hope to expand the system to seven additional facilities.

Results:
Only six guards required to operate the prison facility
Decreased expenses per detainee by 28%
Increased prison capacity
Eliminated roll call checks
Improved use of human and physical resources
Improved staffing levels by more than 20%
