• dango aims to provide the best payment experience for restaurant visitors. The QR code-based payment method allows your guests to pay their bill conveniently from their smartphone without having to call the waiter. dango automatically synchronizes the paid tables with unTill so that your staff saves time which can be invested in upselling and a more personalized service. The dango self-payment solution is usually an additional payment option – guests decide for themselves whether they want to pay independently or prefer to pay traditionally.
