Now you can download our POS App from Microsoft Windows Store! No matter the size - the bigger the better! It works with your 1280x800 or 1366x768 tablet, or if you have the1920x1080 AOI(All-In-One) which will be even nicer!
For WIndows RT device like Surface, it only works as a client, for Windows 8 (including Pro) devices, the POS App can be used as a standalone POS with offline capability. For more details please reference here.
