LF 125/134.2 kHz EM4305 pet microchip with preloaded sterile applicator—ISO 11784/11785 compliant, 1–10 cm read range, multiple sizes for permanent animal identification.
LF animal microchip for permanent identification and recovery. The tag is about the size of a grain of rice and is injected subcutaneously using the included applicator. Once registered, the chip’s unique 15-digit ID links your pet to your contact details for fast reunification by vets, shelters, and animal control.
What is a microchip?
A quick, safe procedure performed by a veterinarian or trained implanter. The tiny passive transponder requires no battery and is designed to last for the lifetime of the animal.
How it helps reunite a lost pet
When a pet is found, an authorized user scans the animal to read the unique 15-digit code. The code is checked with the registration database, which performs security verification before releasing the owner’s contact information to the authorized party, enabling a quick reunion.
