So I’m thinking about getting a system for my new house where you can get an implant and doors will unlock for you automatically. But I also thought it would be cool if you could use those to track where someone (or a pet) was in the house in real time. Well I talked to the VeriChip guys today and they say that only the active RFID tags (ones that have a battery and transmit a signal at all times) can be used for that. The implants are tiny passive RFID tags (they have no battery) so they don’t have enough range to do it.

That sucks… now how am I going to find my cats in the house?? 🙂
