To start a pre-auth from a new ticket, tap the menu button in the upper right (three dots) and select Add Pre-Auth.

The Pre-Auth Amount for new tickets is set to the POS default under Manager > Settings > Business > Advanced in Shift4 Dine.

To start a pre-auth from your ticket list:

1. Select the ticket from the list.
2. Press the menu button in the lower right.
3. Select Add Pre-Auth.
   
   You would typically run a pre-auth from the ticket list for an "Open a tab" ordering flow, where the items are sent, but other items are added to the order.
   
4. Tap or dip the card in the device's card reader.
   
   Once your pre-auth is done, a small credit card icon will appear below the ticket amount for tickets with pre-authorizations.
