Obviously, Chinese customers much prefer to see CNY on checkout when purchasing online. This is true for every consumer purchasing online. Your national currency is generally the most familiar and most comfortable to you.
If your payment form displays a currency other than CNY, this will lead to a bad checkout process for Chinese customers who will wonder:
"Why are payments appearing in USD (or another currency) and not in CNY?"
To solve this problem, we created an integration with a free currency conversion API, which you can setup in the plugin settings under the "Currency" tab. This API integration converts the amount on your payment form (in whatever currency your Stripe account uses) and displays the approximate CNY equivalent for your customers BEFORE they scan the WeChat Pay QR code or get redirected to Alipay.
If you're using WooCommerce, this is an example of what the currency conversion looks like on the checkout page:
Unfortunately, the currency options can be a bit limiting due to Stripe restrictions, but if you have any further questions please contact support.
