Are you one of the people that love photographing? You wish to upload your favorite photos to computer and want to share with family or friends? You want to know the easiest way to tag your photos? If you answered “yes” to all above questions, then I’m want to recommend you a very cool tool here, the “Eye-Fi” SD Card. You must be wondering, why using this “Eye-Fi” since there are tons of different SD cards out there. While you can take pictures, wireless upload and save it to your computer, you can share the pictures no matter you locate.
