They have very little logic, and it requires very little power to make the logic work--about the power generated by an incoming radio signal, in fact. To read it at a greater distance, you use a more powerful read signal, and a more sensitive receiver. It's also possible to read tags in some cases via a third receiver that monitors the protocol between legitimate readers and tags. Passive tags operate at high frequencies that can be scanned by directional beams. There are many possibilities. |
