QR code payment for Restaurants

QR code payment, or what we also call Digital Bill, allows guests to access their live bill by scanning a QR code at the table. From their smartphone, they can review their order, split the bill between several guests, choose their preferred payment method, add a tip and receive a digital receipt. No app download or account creation is required. The experience gives guests more control over when and how they pay. They no longer need to wait for the server to print the check, bring a payment terminal or return with a receipt. The bill can be settled directly from the table, while the restaurant maintains full visibility of the transaction. For restaurant teams, Digital Bill reduces the administrative workload associated with payment. Servers spend less time printing checks, managing complicated bill splits and waiting for card payments to be completed. This allows them to focus more on hospitality, guest interaction and upselling. The payment journey can also include tipping, guest feedback, Google reviews, digital receipts and loyalty features. This transforms the payment moment into an opportunity to improve staff engagement, strengthen online reputation and build a longer-term relationship with guests. Digital Bill is ideal for full-service restaurants, brasseries, casual dining venues, fine dining establishments and any restaurant looking to modernize the end-of-meal experience without removing the role of the server.
