Disabling RFID by mains force

You could try confusing the RFID readers, although how cheap this is
likely to be is unclear:

The Blocker Tag:
Selective Blocking of RFID Tags for Consumer Privacy
Ari Juels and Ronald L. Rivest and Michael Szydlo1

Do RFID tags count as "computers" under the Computer Misuse Act section
1 ("unauthorised access") and the Data Protection Act ?

Would say, Marks & Spencer, be committing an offence if their RFID scanners
picked up a Tesco RFID tag ? Is either company breaking the DPA if, as
now, they use RFID chips which do not have any restrictions on who can
read the information on the tags i.e. they do not have a secure cryptographic
handshake with the reader ?
