Difital Angel's technology provides rapid and accurate
identification, location tracking and condition monitoring
of "high-value assets" when they swim past the RFID antenna
system in a river ... it should be readily adapted to read
such "assets" when they pass through turnstiles, boarding
gates, checkouts etc, when the time comes.

Digital Angel Completes Landmark RFID Antenna Project at Bonneville Dam

Thursday March 23, 9:00 am ET
Massive Antenna to be Installed Today Will Track Salmon in Columbia
River Basin

SO. ST. PAUL, Minn., March 23 /PRNewswire-FirstCall/ -- Digital Angel Corporation (Amex: DOC - News), an advanced technology company in the
field of rapid and accurate identification, location tracking, and
condition monitoring of high-value assets, announced today that its
16-foot by 16-foot RFID (Radiofrequency Identification) antenna designed
to electronically track the salmon population in the Columbia River in
Oregon will be installed today near the Bonneville Lock and Dam. The
antenna, thought to be the world's largest RFID tower, was developed
by Digital Angel in conjunction with the Bonneville Power
Administration (BPA).

The antenna will be placed in the Bonneville Corner Collector, a high-
flow, multi-million dollar surface bypass route developed by the Army
Corps of Engineers and the BPA to move fish safely past the Bonneville
Lock and Dam. The antenna is capable of electronically detecting
previously tagged fish in only 1/30th of a second. Digital Angel is
a leader in developing microchips for tagging fish and large RFID
antenna systems that, despite their size, can detect and read the
standard fisheries encapsulated tags only 12 millimeters long.

When salmon tagged with the passive integrated transponder (PIT)
microchips pass through the antenna, the antenna turns on the PIT tag
and the PIT tag in turn sends a unique identifying number to operators
of the database where important information such as the species,
journey origin and age of each fish is logged. Such information is
critical for maintaining healthy ecosystems for the indigenous fish
population.

"This project demonstrates that our RFID technology has a wide variety
of uses," said Kevin McGrath, President and CEO of Digital Angel. "In
this case, our technology provides the most efficient and least
invasive monitoring capabilities for sensitive objects such as salmon.
This tower will help the local community protect a precious natural
resource for generations to come."

Since the early 1990s, Digital Angel has been developing,
manufacturing and installing implantable passive integrated
transponders and reader systems for the federal Columbia and Snake
River hydroelectric projects. For the past two years, the Company has
been working on the development of large antenna systems, specifically
for the Bonneville Corner Collector.
