After a customer has booked a service from the platform, the platform will issue a booking voucher to the customer. This voucher is a 12 -digit QR code, which we name it as a "Service Code”.
After you complete the service, you need to ask the customer to show the QR code and invalid the code, which means that you have completed the service. The QR code will become invalid after verification and cannot be used again. You can either use a computer to input these 12 digits for verification, or use the merchant APP to scan the QR code for verification.
