Those disagreeing with the research findings believe the paper assumes an
architectural design not in use today. England calls attention to
system-level inaccuracies. RFID tags store numbers, not executable code. The
RFID reader expects the RFID tag

transmit numbers. Not an executable command. If a reader receives executable
code via a virus, it's highly unlikely it would accept the data. 

So since a PHP script expects (say) a street address rather than executable
code, it's highly unlikely it would be vulnerable to a PHP/SQL/XSS injection.

I understand fully.
