The shape of credit cards has not changed since its inception. It is thin and flat - two characteristics that make cards difficult to pick up.
The Curved Credit Cards has a 9° raised corner and requires no extra production material. It is angled just enough to be picked up easily from both the front and back sides. Extra space created by the raised corner protects the IC chip from being scratched when the credit card faces down. Its flexible plastic material allows the Curved Credit Card to be stored flat, with the corner springing back upon removal from the wallet.
