Visual representation at Cashier

Below is a good example of what details at your Cashier may look like:
The customer chooses Bitcoin and receives the details for the deposit - the channel address and QR code for making the payment from the mobile device.
To generate a QR code, you need to use the content of the uri parameter, which you received in the response when creating a channel:
The QR code allows customers to make a payment using a mobile or desktop device, if the wallet is installed on the device. The customer just scans the QR code and then appears a wallet with an automatically pre-filled payment destination address, which is rather a convenient method in the UX context.
Please note that not all wallets support this mechanism - it depends entirely on the wallet developer, but not on Cryptopay.
The cryptocurrency icons that you can insert into your Cashier to indicate the payment method can be downloaded from this link. Alternatively, instead of developing your own design, you can insert a ready-made web page with all the necessary payment details into your UI that looks like this.
