Pre-Auth to keep a tab running via QR code ordering
There is interest to create a completely contactless ordering & payment experience by being able to open a running tab with payment pre-authorization via QR Code. The customer seats themself, scans the QR code on the table to view the menu, adds the items they would like for their first round to their order, they insert their payment information to start their tab and send their first round to the bar/kitchen, the tab stays open so the customer can keep ordering without completing the transaction, once they are ready to leave they close their tab/tip from their personal device and leave without needing interaction from a server. The only contact they have with employees during their experience is picking up their order or receiving it from a runner. The pre-authorization protects the merchant from wine & diners while also creating a more pleasant experience for the customer by not requiring them to complete a transaction for every round of drinks/food.
