The Cartadis cPad is a high resolution, Linux-based touch screen terminal that brings the full functionality of PaperCut MF to almost any multifunction device.
You would use a cPad in the event your existing MFDs are incompatible with a PaperCut embedded solution. This is common among older machines, and also for certain brands. To avoid purchasing embedded-compatible units, the cPad can bring the full functionality of PaperCut MF to these devices. It can be configured as a print release terminal, or as a full MFD interface device.
