I often have problems with magnetic strips on credit cards due to overuse, and have to replace them every few months (after the card gets rejected at the gas station because the strip can no longer be read). The signature on some of my cards also starts to smear and blur from friction so that I get weird looks from sales people who bother to look for a signature.

Of course, there's nothing you can do about the scratching that naturally occurs over time when credit cards are swiped repeatedly, but there's now a wallet specially built to protect them from damage in your purse or pocket. The Silver Wallet available from Zelle for $40.00, is made of lightweight aluminum and contains slots for six credit cards. Its card-spacing feature prevents damage to the magnetic strip, and sliding buttons (which you label with the icons provided) allow you to easily release individual cards. A money clip is also attached, so it makes a good accessory for days when you want to walk around without a purse. Nice minimalist design.
