If you are a demanding Evernote user, Scannable may be the best option for you ... assuming you use an iOS device. Scannable on the iPhone and iPad allows you to instantly scan business cards, sketches, receipts, paper documents and even multi-page documents with ease, and automatically archive and organize the resulting images and files in your Evernote account.
Your scans are automatically trimmed to eliminate backgrounds (such as the table behind the receipt, for example) and are improved so that the text is readable. If you scan a business card, the card's contact information is automatically lifted and added to a contact card, so you can call the person, send them by email or visit their website or social presence with a single touch .
It is relatively new and while it works better with Evernote, it also allows you to share your resulting scan with other applications on your iOS device, so you can upload it to Dropbox, send it by email or save it on your camera reel. The best thing is that it is completely free, it is not unlocked, there is no premium version, although it definitely works better if you also use Evernote.
