If the sale amount from the till is not sending to the Teya card machine, try each step below one at a time until the problem is resolved.
Make sure the card machine is in integrated sale mode:
Check the card machine is connected to the WIFI or has a 4G mobile signal
Make sure the till is connected to the internet. Check the Ethernet cable is connected properly or check the till is connected to the WIFI if using a WIFI dongle
Restart the card machine
Restart the till - Manager Screen, Exit Software, YES to exit, press the Windows button bottom left, press the power icon and select Restart
Test the card machine in non integrated mode. On the main menu select disable integrated mode and then try taking a 1p payment. If this does not work then contact Teya support - 01283 896 876
If needed the card machine can be used in non integrated mode by manually inputting the sale amount each time, and using the NI Card button on the till payment screen to finalise the sale.
If the above has not resolved the issue, please phone for support.
