![]() ![]() At a bare minimum, we looked for a promise that apps won’t sell or share your data without consent. Attention to security: We were skeptical of apps that encourage you (or require you) to upload your scans to their own cloud servers for storage and OCR, as well as those that don’t provide clear security and privacy policies.Diverse format options: You’ll probably end up scanning text documents and receipts most of the time, but a good scanning app should also be adept at capturing material from less-common sources such as whiteboards, book pages, newspaper and magazine articles, and business cards.If the app can automatically back up scans to cloud storage, all the better. Ample sharing options: A good scanning app provides a convenient way to share your scans and OCR results on all the channels you like to use-email, Dropbox, Google Drive, Slack, printers, faxes, and more.Some apps export raw text (either as a TXT file or copied to the clipboard), while others provide formatted text in RTF or DOC files. Accurate text recognition: The best scanning apps use optical character recognition (OCR) to locate text in an image and convert it to an editable document.Different apps provide different scan resolutions and different filters, some of which are better than others at smoothing out wrinkles, shadows, and other blemishes. Great image quality: Although the scan quality is partly dependent on the quality of your phone’s camera, it also has a lot to do with the app itself.We looked for apps with intuitive controls, a thoughtful layout, and helpful features such as automatic document recognition and capture. Ease of use: Above all else, scanning apps need to be easy to use, or else you won’t want anything to do with them.Your phone’s lens can pick up a lot of dust and smudges that can affect image clarity, so give it a wipe with a soft cloth to clean it. This can often happen when you move your phone in to scan the code. If you’ve already made the lighting brighter but the QR code still isn’t scanning, make sure that a shadow isn’t falling on the QR code. Try holding your phone so that the QR code is inside the Nest app’s blue box and then move it slowly away. Some phone cameras can’t focus as well as others close up, so you may have to hold your phone a bit further away. Try holding your phone about 30 cm (1 foot) away and slowly moving it towards the QR code. If you’re holding your phone too close or too far away, it won’t scan the code. Make sure that it’s level with the surface that the code is printed on. Your phone’s camera may have trouble scanning the code if it’s tilted at an angle. You can also try resting your elbows on the table to steady your phone. If it’s shaking too much, your phone’s camera can have trouble focusing. Put your Nest product on a worktop, table or other solid object. If your Nest product is on a patterned background, try moving it to a plain surface and re-scanning the code. Patterns on a tablecloth, rug or wall can sometimes confuse your camera’s auto-focus feature and prevent the code from scanning. Turn on more lights or open the window blinds and try scanning the code again. Your phone or tablet will not use the flash when scanning a QR code with the Nest app, so bright lighting is important.
