If you are integrating this payment solution for the first time, use the \[new Orders API documentation\](https://www.mercadopago.com.uy/developers/en/docs/qr-code/overview). If you have already integrated QR before, we will soon bring more information about the migration process. How it works By integrating QR Code payments through the in-person orders API, your customers can pay instantly by scanning a QR code linked to your Mercado Pago account. When scanning the code, the amount to be paid is automatically displayed on the customer's device, speeding up the process.
