How long does a microchip last?

Microchips have no battery and therefore an unlimited life. The specific reader, which reads the chip, supplies a small amount of energy, which is necessary for reading the data. The microchip can be read any number of times and does not wear itself off. In rare cases microchips can omit and then can't be read by the petWALK pet door any longer. If you believe that the chip of your pet does not work anymore, please contact your veterinarian to check the chip with his hand-held reader.
