The patented BioBond anti-migration cap is a porous polypropylene polymer sheath attached to RFID microchip implants to impede migration of the device within animal tissue. The use of the patented BioBond cap results in increased retention by promoting the development of fibrocytes and collagen fibers around the implant, thus inhibiting movement of the implant within the animal. Migration occurs when the RFID implant moves away from the original implant site. Once a microchip has migrated, it may become difficult to detect and be easily missed when the animal is scanned for the presence of a microchip. Scanners Destron microchips are powered and their identification codes are read by radio frequency signals generated from scanning devices.
Scanners generate a magnetic field that is intercepted by the microchip.
The microchip uses the energy from this field to power itself and transmit a return signal to the scanner which converts it into the microchip's identification code. The resulting alpha-numeric identification code is displayed on a video display or can be relayed via computer interface to other equipment. Depending upon the application, the identification number can be linked with data about the microchipped animal or simply verify the identity of the animal. A small keypad, switchboard, or button provide the user with control over the scanner's operating options. All 134 kHz scanners are programmable to read any microchips conforming to ISO standards.
