I think it's a good idea too. I'd could see sticking one inside the head tube before inserting the fork, or taking the BB out and reaching up and around to stick one inside the bottom of the seat tube. Somewhere hard to find and hard to remove. But I'm not sure if it can be read through carbon.

Figure something like that out and take it on Shark Tank. You can make millions and I'll be a customer.
