Incremental authorisation

1. In the menu, tap Pre-authorisations.
2. Select the relevant transaction in the Pre-auth history list. You can use the filter to search by date, amount, card number, or reference.
3. On the Pre-auth detail screen, tap Increment.
4. Enter the increment amount and tap Confirm. The terminal processes the incremental authorisation.

Once authorised, the updated amount is confirmed and a receipt is printed.

ℹ️

You can repeat this flow multiple times until the final capture, as long as the total amount doesn't exceed issuer or scheme limits. Note that overuse of increments may trigger issuer risk flags.
