... "SmartSeal electronics are being married with both bolt and cable barrier seals and the electronics are available to license by others. The seal combines random codes with a unique tag ID giving high protection against counterfeits, swaps, and hacks. Data storage is variable, 32 to 128 KB. The battery is rated for five years. Range is tunable up to 300 feet. The tags have multi-frequency options, making them more amenable to use across major trading areas. They are also compatible with DoD's 433 MHz RFID reader infrastructure, including those in commercial sea- and airports. An added capability is immediate seal location and status reporting in terminals equipped with a configuration of readers and beacons known in the industry as Real Time Locations Systems (RTLS). Savi reports SmartSeal can be tuned to slot-level accuracy.

SmartSeal was announced in November 2001 and initial sales are reported to Futaba, a Taiwanese electronics firm." ...
