The world famous company Adobe has released a mobile application Adobe Scan that allows you to scan any texts, photos, business cards and documents with your mobile phone.
This incredibly useful application is created using the innovative Adobe Sensei technology, which can independently determine the boundaries of the scanned image and even significantly improve the “picture” of an even perspective and removing shadows.
The mobile scanner will always be at your fingertips and will allow you to make, save and edit digital copies of any images in PDF format.
