So we've offered some advice on how to keep from losing your luggage and your loved ones. But now we have a technology that can protect your most prized possession of all this holiday shopping season: your credit card.

You might find this silly, but we're willing to bet that some people would find some much-needed peace of mind in this "Credit Card Alarm," a wallet-sized electronic sleeve that beeps if it's empty for too long. And depending on your self-discipline, you could quickly recoup the $55 cost of this device by keeping your credit cards in it as long as possible.
