If your customer wants to initiate their Shelterpay checkout via a QR code, you can do this in your Shopping Cart Manager in your Shelterluv account.

Once you have the appropriate items added to the shopping cart, select the blue "Continue with Payment" button. From here, choose the "Generate QR Code" option. Then, select the blue "Generate QR Code" button.

This will generate a QR code that your customer can scan with the smartphone to complete their Shelterpay checkout.
