For the issuer (the bank), it filters out the lowest rung of fraudsters: those who have merely stolen a receipt or a written note.
To answer these questions without getting arrested, criminals rely on a piece of automated infrastructure so specific, so ubiquitous, and yet so overlooked by the general public that it has become the silent gatekeeper of the digital underground: the .
