Windows software with user-friendly interface. You do not need any proprietary hardware therefore you can use any standard PC with two network cards for creating HotSpot billing gateway.
A live Hotspot installation works happily on any standard Windows PC, requiring only an extra network card. Even with a single card you can download and try out the free trial, exploring your simple but very comprehensive and tabbed control panel.The power to easily integrate with other software, such as hotel Internet booking or airline ticket systems, has made HotSpot popular with larger corporations. Extreme flexibility and ease of use make it even more popular as the perfect off-the-shelf solution for smaller operations.
