A microchip is a small electronic device, typically made from silicon or other semiconductor materials. It contains miniaturized circuits and components that are etched onto its surface using advanced manufacturing techniques. Microchips can be used in various applications such as computers, smartphones, and other electronic devices to store data, process information, and control the operation of these devices. In recent years, microchips have also become widely used for identification purposes, particularly in pets and livestock, where a small chip is implanted under the skin and can be scanned to provide a unique identifier.
