I am all about eliminating things I don’t need–especially when it comes to stuff in my wallet. I have a yet-to-be-produced invention that is a “10 credit cards in 1″ device. All you need is one card and a touch of a button on the front changes the magnetic stripe on the back to the selected account: check card, AmEx, FSA, etc.

While I’m working out the kinks on that one (it currently requires 4 D-size batteries), I did come across a site that will allow you to eliminate all those pesky grocery store club cards that dangle from your keychain and hit you in the knee while you drive: www.justoneclubcard.com.

Just gather up all your membership cards and enter the numbers below the bar codes. When you’re done, you have a printable card that can store up to 8 different club cards. Laminate it for extra durability. The people at the register never cease to be amazed by it.
