Definitely not (Score 1)

There are a few reasons why this could be an advantage but many reasons why someone (I) should not do this (most of them are long term ones). My top 3 reasons for not implanting an RFID Tag into my body: * I have to do regular checkups with my tog at the veterinary and from there i know that those implants (of the size of a rice grain) can wander around in the body. This is as far as i know no threat to your healthiness but its unpleasing as they can get unreadable. In this case they can get unreadable and you would have to implant a new one. * If for any reason you want to remove the Tag you need to cut it out (and i really don't like doctors ;) ) * I don't know how good they are protected against this but i think it should be possible to overload this devices in away that they hurt your body. And this would be a nightmare if such "overloading transmitters" would be available to "Script Kiddies". Imagine walking through a shop and some kids walk nearby you and blow your RFID Tag (ouch). Well i think everyone should think more than twice if he implats Something intohis body
