Practically speaking ... let's suppose people have an embedded chip that uniquely identifies them. Lets suppose - amongst other things - this chip can send a signal to unlock your garage or front door. How do criminals gain access to your house? Simple, they gain access to the chip. How do they do this? They dig the chip out of your body with the point of a knife.

This is not fictional thinking. The problem of "kidnapping" has become a big problem in Mexico. One company came up with a solution. If you pay a price, they will embed a tracking chip in your arm. That way the police can find you, if you arw kidnapped. It's a LOJACK system for human beings. So how do the drug cartels deal with this problem? If they think that a person has an embedded chip, they dig it out with a sharp knife.
