Need to quickly scan an administrative document, an identity document or proof? No need to turn on your computer and your scanner: with a special app, your smartphone will give you excellent results.

It is often in an emergency that we need to digitize a document in order to send it to a contact or to transmit it to an administrative service. In these cases, going through the computer and the scanner or multifunction printer attached to it can take time. To go faster, just pull out your smartphone. Packed with high-performance photo sensors, it will have no trouble scanning your document and saving it immediately in PDF format. You can then share it immediately by email or instant messaging. An operation that will not take more than a minute.

To achieve this, you need an application that can scan documents. If you have an Android device, you can entrust this task to Google Drive. The Google app, whose main objective is to manage your Google online space, has a discreet function for scanning documents. Convenient if it comes to troubleshooting and if you do not want to install an additional app on your smartphone, it is however very basic. Some Android smartphones (such as those from Samsung) also have a scanner function integrated into the photo app. Once activated, it makes it possible to recognize a document presenting text then to scan it by focusing on its content. On iPhone, two possibilities are available to you, but lead to the same result. You can go through the Files app or the Notes app. Both allow you to scan documents simply by relying on an identical function.

Finally, if you wish to take advantage of more functions, you can rely on a specialized application. There are several free ones like SwiftScan, Adobe Scan or CamScanner. We recommend the free application from Microsoft: Office Lens. Available for both Android and iOS, it allows you to scan several documents into a single PDF file, add annotations or even adapt the scan to the content (text, table, whiteboard, etc.). She is very good at automatically cropping scanned documents and straightening them to remove the perspective effect.

Last advice before you start: make sure you have good light conditions. Because just as efficient as it is, the photo module of your phone remains small and requires a sufficiently strong luminosity to obtain a satisfactory result. Especially since the documents to be digitized most likely contain text whose readability should be ensured.

Without installing any additional apps, Android has since offered Google Drivedelivered as standard on all mobiles, a scanning function.
