Credit Card Glossary: Terms and Definitions
A signature strip is an area on the back of a card coated with a white or gray material that holds ink. Imprinted above it are words to the effect of “Authorized signature, Not valid unless signed.” Some people write “Show ID” in place of their signature, in an effort to discourage unauthorized use. While that may work in practice, merchants are not supposed to accept such cards.
