UnionPay is the major provider of credit and debit cards for customers in China. While UnionPay cards function much like other credit card transactions, there are some differences. UnionPay transactions are not enabled on your account by default, and require additional setup before you can process them.


Most European merchants can accept UnionPay credit and debit cards using our Android v3, Android v2, iOS v4, and JavaScript v3 SDKs. It is not supported by the Drop-in UI in our JavaScript v3 SDK.

Merchants interested in accepting UnionPay must be settling in USD, GBP, EUR, or CHF. Contact us for information on setup and access.


Transactions made with UnionPay cards require a verification step before they can be processed. At checkout, the customer will be prompted to enter their mobile number, and an SMS verification code will be texted to their device. Once they enter the SMS code, their card is verified and the transaction can be processed. Customers will need to verify each time they make a purchase, unless their UnionPay card is vaulted.

After verification, UnionPay transactions process much like regular credit and debit card transactions and typically settle within 3 business days.


The processing fee for UnionPay transactions is different than your normal rate. You can find the UnionPay processing rate on your pricing agreement. Contact us if you have any questions about UnionPay fees.


The standard chargeback fee for UnionPay transactions is $25 USD – or the equivalent in your settlement currency – and is non-refundable. This fee is applied regardless of the outcome and includes pre-arbitrations.

Fraud tools

UnionPay cards are compatible with most of our Basic and Premium Fraud Management Tools.

There are certain UnionPay cards that do not have CVV numbers, and zip codes are rarely collected with UnionPay transactions. As a result, we will bypass CVV and AVS rules for certain transactions to avoid unnecessary gateway rejections.

Due to the nature of UnionPay transactions and SMS verification, fraud is significantly less likely to occur with these transactions.

Recurring billing and vaulting

After the initial verification, vaulted UnionPay cards do not require SMS verification. We recommend vaulting so customers only have to verify their card with you the first time they place an order.
