You are already tagged in your body.
Units which identify people from a distance via iris scanning, or facial mapping, currently exist and are in use. RFID just happens to be cheaper.
In a few years the other technologies, which do not involve RFID, will likely be cheap enough.
As far as burning out the RFID, the next step is to combine RFID with visual monitoring. A human seen in an RFID-required area whose RFID is not working will just have security come visit him, who will verify his identity and see to it that he gets a new RFID, and bill him for it. After having to pay $20-$50 every time you need a new RFID, the thrill will wear off.

I am not chipped and tracked like a farm animal but they want us to submit to that existence.
It is my understanding that RFIDs can be hacked.
