Easy-Angle / Card

Cards like bank-cards, telephone-cards are usually very thin and are made of hard plastic. It is really hard to pick up a card when it lies on a smooth plane. In order to be picked up easier, a tiny angle of the card could be transformed from plastic into soft material such as rubber or silica gel, which is more flexible and can provide more friction. It is much more convenient to pick the card up by lifting this angle. With no change of its thickness, other functions can be ensured.
