Have you heard of Cardpool.com? It’s a cool website that lets you sell gift cards that you’re not likely to use and to buy others that you’ll definitely use — at a discount. So smart. When it came time to design the founder’s business cards, a gift card look was catchy and appropriate. The company logo is of course center stage on the front, and the back features the contact information arranged to resemble the back of a gift card. Rounded corners complete the effect and bar codes that actually work — the phone number comes up when scanned — add that little something extra.
