4. Types of Microchips
Not all microchips are created equal. There are various brands and types, but the most crucial difference lies in their frequencies. ISO standard microchips operate at 134.2 kHz and are internationally recognized, ensuring broad compatibility with scanners. Some older or proprietary chips use different frequencies, which may not always be readable with standard scanners. To avoid compatibility issues, many veterinarians recommend opting for ISO-compliant microchips for the safest, most reliable identification.
