There’s something about this little shophack that strikes us as very GTD. A Instructables user was sick of carrying several “bonus” cards that had scanable bar codes, so they scanned them into Photoshop, stuck them together, printed them out and made an all-in-one card. So very cool.
You can scan anything with a barcode: Your student ID, Video Store Card, Library Card, etc. One caveat…You might want to use the self-checkout lanes with this baby. We can see the cashiers getting a little freaked out. Thin wallet here we come. —MEGHANN MARCO
