I certainly have too many loyalty cards. I had to make a card holder for all of them! My husband showed me an article on Lifehacker that introduced a product that is pretty neat called KeyRingThing. All you have to do is input the store name and your card number, and it will put up to six bar codes on a card for you! It's free to print at home and get laminated, or they will print it on a sturdy card and mail it to you for around $3. I really like the idea of carrying less around, so I ordered one already. I only had enough to fill up one card since they didn't have bar codes for two of my cards, but I'm pretty stoked about taking six cards out of my purse. Has anyone used KeyRingThing before? Has it worked well for you?
