Cameron Denison, LEED AP, Project Manager -- When you get a receipt for a work expense, write your project / phase / notes on it and lay it on a flat, well-lighted surface. Position your camera phone directly over the receipt and make sure you can see all the text on the receipt. Snap a photo. Now the receipt is in your phone.

At the end of the month, or when your credit card statement arrives, attach the phone to your computer with the USB cord, go to the camera roll on your phone and download your receipt photos to your desktop.  Select them all (left click + Ctrl), right click on one of them and print them to PDF. Since you are printing photos, the “Print Pictures” dialog (or Photo Printing Wizard on some systems) opens and you can opt to put 4 or 9 photos on a sheet. Start with printing 9 to a sheet and verify you can read them after they print. If so, attach your new PDF to your credit card statement or submit it with your expense report.

This works better than trying to save the receipts and digging through envelopes later to make paper copies on the copy machine, or having to position them all perfectly on the scanner. By snapping photos on the spot, you can save some time and aggravation, and you can help save some trees.
