Is there any type of proximity system that detects a microchip or similar? I am looking at an "mobile" proximity detection system that I could specifically detect an implanted or imbedded microchip or something that it would be designed to only detect that object. It would also be very beneficial to be microchip size. This would be for an industrial application. Thank you in advance. JL

They are uniquely coded so no two cats (or dogs or rabbits) have the same number.
Here's the wiki link.
