How do I start the payment process with the Terminal App on my S1F2 and how is the merchant or customer receipt printed?

Click on the purple "luca" icon on the terminal home screen in the upper left corner.
Enter the amount and click on "Continue".
Then your guest can give a tip.
Your guest can tap their card on your S1F2 and enter the PIN if necessary.
You will immediately see whether the payment has been accepted (“approved”) or declined (“declined”). Please make sure that the payment was successful.
In the end, the customer can scan a QR code and have the receipt sent to him via E-Mail.
In your luca Location Account, you can send the merchant receipt to your stored email address at any time.

Please note: The customer receipt is not a hospitality receipt with VAT, just the payment receipt.
