A quick google revealed that there's a company doing that. I'm not affiliated with them, but I'm still not going to name them or post a link. If you're interested, google "rfid musical instrument". They claim, of course, that their tags (and warning stickers) prevent theft and aid recovery. The price is reasonable, so I'll probably give it a shot.

Putting the device in is easy. The problem is that essentially no one has the scanners to read the codes and then there's the question of who they should call to match you up in the database.
If it's to prove that a piece of equipment is yours and you have you own scanner, that's one thing, but to expect that it will help locate an instrument out there is unrealistic, hence the numerous false starts for the companies offering that service.
I've suggested several times that these firms supply chips to all guitar makers free of charge to be embedded during manufacture and make their money when the customer signs up for the service. But they have to distribute readers to essentially every police department and get chips in all kind of devices, such as skis, for example, to build the largest number of protected units out there to make it worthwhile.
The concept has been used for years with pets (Smokie has an implant) but is only just beginning to get traction but I seriously doubt both the rate of recovery and profitability. The pet model is also much more workable, because most people do the right thing and see lost animals get to a shelter at some point, which is likely to have a reader due to the efforts of the recovery services. Lost or stolen guitars, on the other hand, tend to stay out there and few are going to come under scrutiny of the police, nevermind an rfid reader.
