# UnionPay

UnionPay is the largest card payment network in China and one of the largest in the world. Accepting UnionPay on your website allows you to offer Chinese customers a familiar and trusted card payment method directly on your checkout page.

## Why Stripe + UnionPay?

Stripe supports UnionPay card payments, allowing you or your business to accept card payments from Chinese consumers who hold UnionPay-branded debit and credit cards. This integration works seamlessly through the Stripe API, just like WeChat Pay and Alipay.

## Inline Card Entry

Unlike WeChat Pay (which uses a QR code) or Alipay (which redirects to the Alipay website), UnionPay card payments are entered **directly on your checkout page**. There is no redirect — customers enter their card number, expiration date, and CVC in a secure, Stripe-powered inline card form embedded in your WooCommerce checkout.

{% hint style="info" %}
The inline card form is powered by Stripe Elements, which means card details are handled securely by Stripe and never touch your server. This keeps your checkout fully PCI compliant.
{% endhint %}

## Supported Currencies

UnionPay card payments support a wide range of currencies through Stripe. The currency displayed at checkout will match your store's default currency. For the full list of supported currencies, refer to the [Stripe documentation on UnionPay](https://stripe.com/docs/payments/cards).

For more information, check our documentation on the [UnionPay User Experience](/payment-methods/unionpay/unionpay-user-experience.md).
