RFID does not protect technology. Saying something is "RFID-protected" is just like saying "my access point is WiFi -protected". Eh?

RFID is a carrier technology, with a number of different frequency bands, with each of their own application area: some can be read from afar, some offer high transfer speeds, some work well close to metal, some need large antennas and some need small ones.

Some RFID tags just contain an ID (and are usually of high range and low speed), and some tags contain loads of data (meaning a low range and high speed). Unfortunately, people tend to lump all RFID as a single thing, which muddles things somewhat. However, they have no more in common than say, HAM radio and WiFi. You can't say that WiFi is bad because HAM radio lacks security ;-)
