Thats because a little tag on the products alerts the sensors...how is this different from RFID?

Those little tags are either removed or deactivated before you leave, which is how you can go past the sensors without them going off. I've taken one of them apart before; they're little strips of metal that can hold a magnetic charge. That's a bit different then the many bits of data that can be included in an RFID chip.
