A shared restaurant wallet could let customers use prepaid value across participating venues. Before building, define the payment model, who holds funds and how balances and refunds will be managed, with appropriate specialist review.
Venues need a consistent transaction record and a way to reconcile use across locations. Balance changes should be traceable, with safeguards against a retry creating a second debit. Customers need a clear statement of participating venues and applicable terms.
Pilot a limited group and test a split bill, a reversed transaction and a venue temporarily offline. The visible balance is only one part of the product. Reliable accounting and a confirmed operating framework are essential before promising that value can be used freely across every venue.
