It may pay off for a well regarded breeder to document their own line or to prove that something was produced by them and also to help with proof when a valuble snake is stolen. Every Vet and shelter has scanners. It is not hard to gain access to a scanner. The producer of the snake that is implanted with the chip would be the defacto registry for his own snakes. Anyone could have a snake scanned and contact the breeder with the chip info to verify whether or not it matches the breeder info. It would also be registered with the company that sold the chip. It would probably add $50 to the cost of a snake. If somebody started doing this, soon others would probably follow suit.
