Re: RFID tags subject to viruses ...


some tags are ready only. - so can't store a virus

some tags are only 96 or 128bit, - which is only 12 ~16 bytes  (hardly
enough to store a virus)

some tags have 48, 64 and 128bit encryption (so the encryption has to be
cracked 1st)

most RFID tags are small memory size  and not enough to hold a virus.


Contact smart card which have large memory HOWEVER may be able to hold a
virus.


The Wallmart /  Kmart tags in the article are typically  12~16bytes


Sounds futuristic
