How does a microchip work in dogs? - briefly
A microchip for dogs functions similarly to an ID tag but is implanted beneath the skin. When scanned, it transmits a unique identification number that can be traced back to the pet's owner through a national database.
How does a microchip work in dogs? - in detail
Microchips used for identification in dogs are small, passive radio frequency identification (RFID) devices that operate without an internal power source. They are typically encapsulated in biocompatible glass and contain a unique identifier that can be read by a compatible scanner. Here is a detailed explanation of how microchips work in dogs:
When a microchip is inserted under the dog's skin, usually between the shoulder blades, it remains inactive until activated by an external scanner. The microchip contains a tiny transponder with an integrated circuit and an antenna. This antenna picks up the radio frequency signal emitted by the scanner.
Upon activation by the scanner's signal, the microchip's integrated circuit is powered up briefly. It then transmits the unique identification number stored in its memory back to the scanner via the same antenna. This process happens almost instantaneously and does not cause any discomfort to the dog.
The scanner receives the transmitted signal and decodes the identification number. This number is typically 15 digits long and is linked to a database that contains information about the dog, such as its name, breed, owner's contact details, and veterinary records. By accessing this database using the unique identifier, pet owners and animal shelters can quickly retrieve crucial information about the dog.
Microchips are designed to last the lifetime of the dog without needing replacement or recharging. They are highly reliable and resistant to damage from normal activities, including swimming and playing. However, it is essential to ensure that the microchip is registered in a database and that the contact information is kept up-to-date to maximize its effectiveness in reuniting lost dogs with their owners.
In summary, microchips in dogs function as passive RFID devices that store a unique identifier. When activated by an external scanner, they transmit this number, which can then be used to access important information about the dog from a linked database. This technology plays a crucial role in pet identification and recovery.
