Don't Let the Payment Ruin the Dining Experience: Revisiting Digital Payments in Restaurants

Restaurants serve as dining spaces, workplaces, and social hubs but face persistent challenges such as high stress levels, irregular hours, and labor shortages. These factors hinder not only service efficiency but also affect customer satisfaction. Payment processing is a critical touchpoint influencing both staff coordination and customer experience. Traditional methods, particularly bill-splitting, create logistical inefficiencies, delaying table turnover and increasing staff workload. Through focus groups and semi-structured interviews with restaurateurs, service staff, and guests, perceptions of payment processes were examined and potential technological improvements identified. To address these challenges, an existing prototype was enhanced to allow guests to complete payments individually via their own smartphones. Unlike fully digital ordering systems, this approach preserves staff interaction while streamlining payment-related tasks. The prototype's impact on service efficiency and customer satisfaction was evaluated using the “Thinking Aloud” method. Findings indicate broad acceptance of payment process optimization among both guests and staff. Enabling guests to pay specifically for their individual consumption is perceived as beneficial, as it streamlines separate billing, minimizes errors, and shortens payment processes by reducing the need for clarification or negotiation. While personal interaction and tipping behavior remain crucial considerations, self-service payment after the meal is largely unproblematic. The proposed system minimizes time-consuming payment steps while maintaining meaningful staff-guest interactions, enhancing efficiency and customer experience. This study contributes to the broader discussion on integrating digital innovations into service workflows without diminishing human interaction.
