Yes, I was thinking of the way too many people who think you can get a working chip through a needle. It's even harder to make something that you could eat. It has to be resistant to hydrochloric acid. That's reasonably easy, just expensive. It has to be food grade, so PTFE is probably the only choice. It will last in the digestive system for a day or so then passed with all the waste into the sewer system.
How are you going to track what chip goes into each person anyway? How are you going to power it? If it is passive, the transponder power will have to be substantial. If powered, it will have to have a power source. Practically, it is impossible. It would be very easy to defeat, even if all the obstacles were overcome. I have a sleeve over my debit and credit cards that blocks RFID. It would be easy enough to make clothing with RFID blocking.

I think your misunderstanding the purpose of the RFID's that I mentioned in the original post to you. The RFID's in the links I gave go into different food products and other merchandise and are to so they an track them. In other words they are put into things like a bag of flour or corn meal and then they an track it. When we use the product it eventually ends up in the food you ate and then which ever member of the family ate it then in turn deposits it into the toilet. The reason they are trying this is for instance if you have wieners,relish,hotdog buns but no mustard in your icebox then they know to show you commercials for mustard on the TV. Anyway they are not intended as a way to track you,,,but instead a way to track the products inside your home.
