Unlike conventional computer driven Bed Scanner that takes minutes to scan a photo, the Wolverine Photo Digitizer converts Photos into digital in SECONDS. Now you can take stacks of photos and convert them into digital images to share and preserve them forever. Wolverine has created a simple-to-use device to convert 3x4, 4x6 and 5x7 photo prints into 20 Megapixel JPEG digital imaged in seconds. NO COMPUTER OR SOFTWARE IS NEEDED, Plug-and-Convert into the built-in memory or to an SD/SDHC memory card. Offload saved images by plugging the unit into Windows or Mac USB port without software or loading in drivers.
