Digital Angel, a GPS and RFID tracking company, has acquired Geissler Technologies Corporation, a developer of electronic identification and imaging technologies for animals.

Geissler will be incorporated into Destron Fearing, Digital Angel's existing animal applications business.

The acquisition brings back a founder of Destron Fearing, Randolph Geissler, who will again become president of Digital Angel's animal applications business.

Joseph Grillo, chief executive at Digital Angel, said: "We believe that bringing a founder of Destron Fearing back to our company and the intellectual property and products of Geissler will further ensure that we realise our growth expectations."

Digital Angel uses RFID and GPS technologies to enable the rapid and accurate identification, location tracking and condition monitoring of people, animals and high-value assets.

"The technologies developed by Geissler include g.TAGT, a low frequency RFID device used for animal traceability, and the r.TAGT high-frequency long-range anti-collision device used for extensive animal management," said Grillo.
