b/S (WEB) system using the ActiveX plug-in call scanner for continuous scanning and upload images (ie file scanning and automatic upload)

Using the ActiveX plugin to invoke the client scanner to scan files and mountain pass, You can scan the paper files (such as contracts, documents, materials, etc.) and save the scanned images to the server, which can be used for contract management, file management, etc.

By invoking scanner scans and acquiring images via plug-in mode, you can reduce user actions, reduce operation errors, such as large scan volume or continuous scan, which can be used to number scanned files or other processing by the system.

The Web page only needs to start the scanner scan after the JS call, you can get the image encoding of the scanned files, and then the Ajax or form submission to the server decoding after the save as a JPG file.

Through the server program processing, you can easily browse or to other users to share!
