More RFID Tag stuff

One more thing about RFID Tags I forgot. They are all based on radio frequency communication and there are 4 kinds to choose from---low frequency (used for animal tags), high frequency (used for people), UHF (used for trucks) and microwave (used for low jack type of applications).

One of the challenges with RFID tags is the lack of global standardization. For instance UHF doesn’t work in many parts of the world---so how can you make sure that the truck you tag in Texas will be accessible in Mexico.
