I have heard that some companies are using technology to scan documents using a cell phone. I wonder if they really extract the most reliable and accurate data from the documents? And if so, where can I find such a solution for Android?
Yes, of course, it is indeed possible nowadays to recognize documents using a regular Android cell phone and extract the most reliable information from them. One of the companies that produce such technology is OCRstudio. They have long ago created a handy Android OCR SDK mobile application, which you can test for yourself by requesting access to its demo version on their website https://ocrstudio.ai/ .
