I saw the TV programme, and felt just as poorly informed then. There are 
some interesting forensic aspects: he says the card was only used once 
to change the PIN, then locked in his safe. Is it possible to tell how 
many times a card has been used, by examining the card? (If not adding 
some sort of "counter" into them might a good idea for the future).

Presumably they've done things like check to see if he made any large 
purchases with cash, that can't be explained by withdrawing the money 
from his regular bank account.
