Why you can trust TechRadar
Use cases
The ScanSnap is ideal for people who constantly gather business cards, photos or other paper items that don't necessarily require physical copies. You can quickly load a business card into the machine, scan it and then use the device's CardMinder tool to store the card-owner's name and business information.
It's also great for organizing receipts from business trips or from the grocery store.
You won't want to use the ScanSnap for multi-page scanning. Because you need to load each page individually, the scanner is best-suited for one-off scans. If you need to create a PDF of your graduate thesis, then your grandfather's scanner is probably a better bet.
Speed
The ScanSnap is incredibly fast. Fujitsu says the scanner can create a digital file of a Letter page in 5.2 seconds. I actually had a better experience. My full-color image was sent to and pulled through the machine in 3 seconds.
The business cards I scanned went through the device in about one second.
If speed is your top requirement for purchasing a scanner, and you're only concerned with one-off scans, you'll absolutely love this machine.
Flaws
Because the device is so good at recreating images, you'll find that less-than-mint images will look even worse in digital formats than they do on paper. Dust, creases, and scratches will appear on images if the pages aren't completely clean. The image I scanned looked perfectly fine to the naked eye, but the scanner returned the following digital file (click to expand to see flaws):
The device claims to offer "Automatic Image Stitching," which allegedly connects folded or disattached images along their centerlines. I tried to do this, and it does work, to an extent; however, the image created won't be exact and you'll definitely see creases or tear marks when the final digital image is created.
Smartphones can create digital files of images. It's called a camera. If you simply take a photo of your receipt or document, you can run the file through Photoshop to convert it to a PDF or a JPEG. This means the ScanSnap is doing something you could already do. However, it does make it easier and more practical - if you're willing to spend almost $200.
We liked
The ScanSnap is incredibly fast, versatile and handy. It's a small device that can travel with you wherever you go and it can send your files wherever you need them sent.
We disliked
Because it can only scan one page at a time, you'll likely want to use a normal scanner for multi-page jobs. Also, be careful how you treat your physical files - the ScanSnap will copy all image flaws (even the ones you can't see) and reproduce them on digital files. Because this is a luxury item and not a necessity, you may not want to spend $200.
Verdict
I thoroughly enjoyed using the ScanSnap. It made creating expense reports and storing business cards easy and fast. It was so much faster than Fujitsu advertises it to be, which is always a pleasant surprise. However, I'm not sure I'd spend $200 on something that can only be qualified as a luxury item.
