Cheque Mate
Time for the resurgence of the cheque (PITA that most UK places hate them now)
A scribble that has varying degrees of difficulty to forge, and also needs a card to be presented with it, but as you inevitably get your fingerprints on cheque when handling it, if you have used it will have your prints in a few places so can prove if fraudulent use as they can lift prints from the cheque.
In worst case scenario, if your cheque book is nicked, only really a chance of stray prints of yours on the "top" cheque (you may have got prints on when removing last cheque) and as likely to do fraud with > 1 of your cheues then pattern of dodgy use (without your prints) will be convincing evidence that "top" cheque was also a fraud transaction
