Scanique.Web provides web-access to any scanner. Get your documents scanned anywhere, using every internet-connected device.
Access to the scanner occurs through any modern web-browser. That means you can access your scanner from any device with a browser, such as computers under Windows, Mac OS, Linux or even Android, Apple or Windows tablets or smartphones. By having Scanique.Web installed, you get access to your scanner on any modern device with a web-browser from the other end of the world... or maybe just the next room.
To share a scanner, all you need to do is to download and install Scanique.Web on a computer with scanner or MFP (Multifunction printer) attached to. You don't need anything else to access the scanner from other computers, which is pretty cool.
Scanique.Web supports all TWAIN scanners (that is almost all scanners) and works with all modern browsers.
