I wonder how easy it would be to jam/spoof RFIDs.
I doubt there is any crypto in them that
guarantees the authenticity of an RFID nor any
form of tamperproofness on the physical device

I also doubt that they are particularly robust
w/r/t radio noise.

I wonder how hard it would be to walk into a store
with a jammer, pick up a bunch of stuff and walk

Alternatively, how hard would it be to walk into a
store and claim to be someone else?
