Microchips are widely compatible with scanners used in veterinary clinics and animal shelters across many countries. Most modern scanners are designed to read microchips from different manufacturers, adhering to international standards, such as ISO 11784/11785. However, there can be exceptions, particularly with older or non-standard microchips that may not be detected by all scanners. Pet owners should ensure their pet's microchip complies with current standards to maximize the likelihood of detection across various facilities, enhancing the chances of reunification if the pet is lost.
