Think about it, at any given time, you carry your ID, credit cards, debit cards and a large of cards with magnetic strips on it. When you carry the cards around, the strips tend to rub against the coins, notes and keys that you carry. And sometimes, the strip goes dead simply because it has been completely destroyed by everything rubbing against it. The Aluminum Wallet is a hard case which prevents all that. When you place your cards in this, they stay in place and there is no chance of any card damage. If you have a leather wallet, you might have already experienced this problem. It might have been made out of the best leather but once you put it in your handbag or your back pocket it is going to bend. And of course, the cards are going to bend with it. This means, one fine day you might be trying to use your cards and the cashier will refuse it saying that the card is inactive!
