Unusual applications

Monitoring efficiency of postal systems

Kasten Chase Applied Research have recently been awarded contracts by various postal authorities to supply systems to evaluate the efficiency of the postal services. In one application the system comprises of 100 000 transponders that are placed in test letters and posted from a variety of different locations to different destinations, with their progress being monitored by readers in 185 locations. The readers are capable of identifying the letters at a distance while still in the mail bags. Using such systems the performance of postal systems across international boundaries can be evaluated.

Studies of fish migration

PTAGIS: Passive Integrated Transponder (PIT) Tag Information System
The following is an extract from the description paragraph of this site
What is PTAGIS?
Since 1985, researchers have employed electronic identification (EID) in studies to learn about migration characteristics of juvenile salmonid in the Snake and Columbia river drainages. A Passive Integrated Transponder is implanted in juvenile fish. A network of interrogation systems located at hydro-electric projects and other interrogation systems located at juvenile fish traps passively collects information about individual fish as they migrate down river.

The PTAGIS project is a data managment project. Our mission is the collection and distribution of PIT Tags and PIT Tag data for the Columbia River Basin. Included in our data management responsibilities are data verification and data integrity, interrogation hardware and software maintenance and operations, and development and maintenance of various other software and PIT Tag related processes.
