Hidden Card! This concept is mainly for credit card holder who usually face fraud activity. An amazing design. South Korea-based design team from the Korea Armed Forces Printing Publishing Depot has designed a new type of fraud-proof credit card. The design, knows as "Hidden Card", is a concept where the CPU, operation system, memory area and security algorithm are built into integrated circuit (IC) chip card. IC chip is a technology that is easy to duplicate than magnetic cards. This design takes security up to a whole new level by placing the IC chip within the card, only to appear upon keying in a certain code. This concept offers a greater, more secure credit experience that is definitely way of the future.
