Loyalzoo can run as a "floating" button on top of any EPOS software (Windows based systems), as long as the terminal has a direct connection to the internet.
Here's what to do:
Download the Loyalzoo Windows installer here: http://downloads.loyalzoo.com/windows-pos/loyalzoo-install.exe
On the POS system, run the installer. The installer will require your merchant Loyalzoo credentials (username and password) and will then download and install the software. It will also install .NET if it’s not already installed
The installer will also add a shortcut to the startup folder so that Loyalzoo starts automatically at startup
If you need to adjust the size of the button or the window, you can edit config.xml file in <USER_HOME>\Loyalzoo\Release\config.xml.
Please get in touch if you have any questions.
