Take a card payment
On the SumUp app, open the "Checkout" screen.
Enter the transaction amount (minimum £1.00) or choose an item from your item catalogue.
Tap "Charge" and select "Card Reader".
Prompt your customer to pay by either tapping their card for contactless payment or inserting it into the Air Reader and following the on-screen instructions.
Your SumUp Air will show a confirmation message and you can optionally choose to provide a receipt.
