As smartphones improve their cameras, they can be used more and more as portable documents scanners (with special Apps). Nevertheless, this works better for smaller items, such as receipts. Trying to scan an A4/Letter sized sheet of paper can be tricky (especially, when you try not to cast a shadow with the phone over the page when you take the picture). If you have several pages to scan, it is a chore.
Doxie has a range of extremely portable scanners to help you archive all those pesky bits of paper, including a raft of A4/Letter sheets. There’s the Doxie One, The Doxie Go Plus, Doxie Go Wi-Fi, and some other variants on those two. Let’s focus on the Doxie One and the Doxie Go Wi-Fi, as these are the most interesting in terms of features and purpose.
Both Doxie scanners are similar in size (comparable to a rolled-up magazine or empty roll of paper towel). They are both self-powered. The Doxie Go Wi-Fi has a built-in rechargeable battery (up to 300 page scans on one charge), whereas the Doxie One uses 4x AA batteries (which could be rechargeable, if you so wish). The Doxie Go Wi-Fi has more features, such as built-in Apps that let you sync your scans directly to the Cloud with services such as Evernote, Dropbox and Adobe. The Doxie One does not. Instead, it uses an SD card, which you can shuttle back between your laptop or Tablet (The Doxie Go also has an SD card for similar use).
The Doxie Go Wi-Fi has one up on the Doxie Go Plus in that it supports direct syncing to iOS devices. It also allows itself to be a network-scanner, so you can attach it to your local network and scan to other devices sitting on that network. There is also a “iPhone/iPad Sync Kit” that you can buy for the basic Doxie Go that includes an Eye-Fi card to send scans wirelessly to iOS devices.
The Doxie One is limited to 300 dpi scans, whereas the Doxie Go range support both 300 and 600 dpi. Both models have OCR built-in (ABBY), so that they can produce archival pdfs that are text-searchable. Scanning a 300dpi A4 colour page takes about 8 seconds.
In summary, if you are looking for an inexpensive, ultraportable, battery-powered scanner that is very simple to use and gets the job done, this could be it. There is only one button to mess with and there are a variety of models to choose from depending upon how important Wi-Fi and device connectivity is to you.
