Smart Selection is a feature which learns what is your preferred method of taking payments and makes that method the default. To enable this, please follow these instructions.
Step 1:
Go to the More page (the list icon on the bottom right of the app).
Step 2:
Scroll down and navigate to Smart Selection.
Step 3:
By default, all payment types are considered for being the preferred method of payment. You can toggle this if there is a payment method you do not want to be considered as being the default.
Step 4:
Select the Charge page (2nd icon at the bottom). And put a test payment value in e.g. £10.00 and press Charge.
Step 5:
Select the payment type you would like to use for Smart Select, e.g. card reader.
Step 6:
Cancel the Charge.
Step 7:
Once Smart Select has been successfully set, you will see the default payment method as a new button alongside an option for 'Other'.
