E-C / Bank card


In life there are many inconvenient places, such as picking up the bank card when it drops on the ground. Especially in the case of there is water on the ground, picking up the card will become a very difficult thing. Thus, we designed a card, not changing the basic structure of the original card,but cut a triangular pyramid on the four corners of the card , so that each face will have two small plane who have 2-degree angle with the face. When the cards fall to the ground, we simply hold down the corner of the card, and the other half of the card will be lifted, so it will be very easy to pick up the cards.
