[Snapshots from the end of democracy] Texas police are asking stores to take fingerprints of all customers who pay by check under the auspices of a plan to reduce fraud.
The systems range from an inkless pad in which the chemical easily rubs off the skin, to an electronic sensor that compares a customer's print to a pre-scanned fingerprint, Crouch said. Another system involves a clear chemical that leaves a blue imprint when pressed onto a chemical-sensitive sticker that is usually placed onto the back of a check.
