When people use bank card in boxy shape, it is really sort of inconvenient and difficult for them to distinguish its inserting side, especially for the blind and the visually impaired. Based on it, “CLEVER CORNER” bank card can make people tell the front and back side of the card more directly by changing the shape of the card when they are using ATM.
