Security improved card
A security improved credit, debit, pass, or cash card is a colorless and transparent semirigid plastic card member with non reflective faces, with no permanent imprinting on the card member to visually identify an issuer, an owner or a card number, but with temporary identification that can be removed by the owner of the card and can be visually read only when backed by an opaque sheet. The card has a bending line across a face of the card member that is a slit through the card with a hinge of flexible plastic film attached over the slit. The card has an opening cut through the card member to allow a person's finger nail to engage the opening to pull the card from a wallet or to attach the card on a shirt button.
