Some credit cards have a "smart chip" embedded into the card. The aluminum case protects your cards inside from being read electronically. It basically acts as a RFID blocking wallet. It is made of sleek looking, lightweight, brushed aluminum. The accordion inside holds about 7 cards plus a small amount of folded cash. Due to the compact design, (to fit in front pockets and small travel bags), it is not recommended that you exceed the recommended number of cards.
