Creates a new QRCode if code is not suppled . If code is supplied and merchantId and useReservedQrCode is false then all other fields are ignored and the existing code is looked up and linked to the wallet. Note a code can only be linked to one wallet at a time. Once created/linked it will appear under the wallets mappings. The behaviour of the QRCode depends on the type. Typical behaviour is when a compatible App pays the QRCode, the value will appear in the mapped wallet. If code is supplied and merchantId, useReservedQrCode is true then code will be linked to wallet for supplied merchantId
