Problem: Crash Freeze MPOS SHUTS DOWN WHEN SWIPE CREDIT CARD

Resolution:

This happens because certain options are activated unknowingly. Most commonly when the option to prompt for credit card info has been selected, (Setup Wizard-General Setup) If you are using X-Charge or PC Charge you do not need to check the prompt for credit card info this check should be left unchecked. Otherwise using a USB or keyboard wedge scanner will scan the data where ever the prompt is causing the system to close down or minimize.
