These days, more and more cameras come equipped with Wi-Fi so you can wirelessly send images to a printer or a friend’s e-mail. Have an old digital camera? Don’t worry, you can do the same with an Eye-Fi card. If you can manage to snap a picture of your exam using your digital camera, you can send the images directly to your friend’s phones or e-mail, or even to a Wi-Fi enabled printer. Of course, you can do the same with your phone.
