Product Ecosystem

Bank Card Clearing Network

UnionPay's core business is clearing and switching bank card transactions. When a cardholder makes a purchase using a UnionPay card, the transaction is cleared through the UnionPay network between the issuing bank and the acquiring bank. The network supports debit cards, credit cards, and prepaid cards, processing transaction volumes among the highest in the world.

Cloud QuickPass App

Cloud QuickPass is UnionPay's consumer-facing mobile payment platform, integrating QR code scanning, NFC payments, online payments, money transfers, credit card repayment, and utility bill payments. A key differentiator is its interoperability with bank apps — users can manage cards from hundreds of banks in one place.

UnionPay International

UnionPay International is the cross-border business brand responsible for expanding overseas acceptance networks and local card issuance. As of 2026, UnionPay has issued local cards in 60+ countries and regions, with over 30 million overseas merchant acceptance points.

UnionPay Open Platform

The UnionPay Open Platform provides API and SDK integration capabilities for merchants and developers. The platform covers payment, identity authentication, and data service interfaces, suitable for backend integration scenarios.

Limitations

  • Insufficient Online Coverage: While UnionPay's offline acceptance has expanded rapidly overseas, its acceptance rate in international online e-commerce scenarios remains significantly lower than Visa and Mastercard. Cross-border online shoppers may still need an international credit card.
  • Lower Mobile Engagement: The Cloud QuickPass App has 400M+ users, but daily active usage in small-ticket, high-frequency scenarios (convenience stores, restaurants) is notably lower than Alipay and WeChat Pay.
  • Developer Platform Experience: Documentation quality, technical support responsiveness, and API sandbox environment stability still lag behind platforms like Stripe.

Use Cases

  • China-Facing Payments (★★★★★): Almost every Chinese consumer holds a UnionPay card. Integrating UnionPay is a baseline requirement for China-focused e-commerce and apps.
  • Government/State-Owned Projects (★★★★★): In projects with strict regulatory compliance, UnionPay is the default payment channel. Requirements analysis should clarify UnionPay integration scope.
  • Chinese Outbound Tourism (★★★★): UnionPay cards enjoy broad acceptance at overseas merchants targeting Chinese tourists.
  • Cross-Border Merchant Collection (★★★): UnionPay International supports local card issuance abroad, allowing cardholders to use local UnionPay cards for purchases.
  • International Online E-Commerce (★★): Online acceptance trails Visa/Mastercard. Consider adding PayPal or other international payment platforms.

Pricing

As a clearing organization, UnionPay's fees consist of three parts: issuing bank service fee, clearing network service fee, and acquiring service fee. Standard rates vary by industry:

Industry Category Debit Card Rate Credit Card Rate Cap
Standard 0.35% 0.45% 13 RMB debit cap
Discounted (supermarkets, gas stations) 0.28% 0.35% 8 RMB debit cap
Exempt (charity, healthcare) 0% 0% None

Above are UnionPay clearing-side reference rates. Actual merchant discount rates are determined by acquiring institutions adding their service fees on top.
