Manufactured in France, the ALLFLEX transponder is composed of an electronic chip onto which a unique identification number is programmed, a copper coil and a capacitor, all encapsulated in a bio-compatible glass tube.
The ALLFLEX transponder is a perfectly passive (inert) element.
As small as a single grain of rice, the ALLFLEX transponder is injected under the animal's skin using a syringe, usually on the left hand side, in the jugular vein of dogs and cats.
This operation is only performed by a vet.
