Welcome to this survey on evaluating the first prototype for a cashless tipping app. The purpose of the web app is to facilitate transactions between restaurant and bar staff with customers wishing to tip them for their services. An employee is able to set up an account and generate a QR code, which once scanned by a customer will direct them to a payment page to send a tip. The aim of the survey is to receive feedback on the design of the web app and to assess whether the overall functions are usable. Thank you for taking time to complete the survey, your honest feedback, whether positive or critical, is greatly appreciated.
