RFID

RFID - radio frequency identification is some scary shit. It's basically a device whereby the tag can be found via radio waves. Weird... They can be put on clothing, cars, etc. Apparently the radio waves get messed up by water, so I guess, in theory, they don't work well implanted in the body. There are also different frequencies (high, intermediate, and low), which correspond with diffretn ranges whereby the tags can be read. The cool (albeit scary) thing about RFIDs is that you don't necessarily need to see the tag in order to read, hence unknown tracking. I guess in this day and age, people might start RFIDing their kids and partners...creepy. What happened to good old shoplifting, gate jumping, and sneaking around?
