Neat receipts, something to read about
This has probably resulted in a lot more business cards than you are able to handle. All of the important details that are printed on these cards wouldn't be of much use to you unless you could find a way to store them into your computer somehow. And for that a business card scanner is one of the most useful devices. Now, you may have already been using a Rolodex all these years, and have managed to keep your contacts tidy so far. You will notice however that this can get full pretty quickly, and it won't be long before you will have to weed this out.
