Learn about the UnionPay checkout experience for your customers on desktop and mobile devices.
When a customer selects UnionPay as their payment method during WooCommerce checkout, they will see a secure inline card form directly on the checkout page. The form includes fields for:
Card number
Expiration date
CVC
After entering their card details, the customer clicks the "Place Order" button. The payment is confirmed instantly via Stripe, and the customer is redirected to the order confirmation page.
There is no redirect to an external page — the entire payment flow happens on your checkout page for a seamless experience.
On mobile devices, the UnionPay inline card form is fully responsive and works seamlessly in all mobile browsers. Customers enter their card details just as they would on desktop, and payment is confirmed instantly.
