How does a scanner work, for a microchip?

I know an organization, has to buy the scanner, and they run it across the back of the pet, similiar to your products being scanned at a grocery store, and it registeres, with the microchip #.

But what actually powers the scanner. Does it run on batteries, is it plugged in, similiar to a cell phone. Is the organization charged, each time they scan a pet.

Got into a discussion, with a co worker, who 99.9999% of the time, is right. This time I think, he is wrong. He said, the organization, is charged, each time, they scan a pet.

So, how does it actually work? waveway to gohug

The scanners I've seen are battery powered (no plugs.)

Basically, the scanner sends a RF signal to the microchip, and the microchip sends back the ID number.

I do not know of any that charge for using the scanner, I don't see how they could charge? All the scanner is doing is basically "reading" the number that is on the microchip. If this is a lost pet, the person then has to look up that number to find out who the pet belongs to.

Harlequin is right about how the chips work. The chip companies make their money from selling the chips not from the scans.
