Why ZaloPay is essential for merchants in Vietnam featured image

Cashless payment is fast becoming the norm in Vietnam, backed by growing support from the national government.

Non-cash payment transactions grew by 63.3% in January 2024 compared to January 2023, with mobile payments and digital banking leading the charge. QR code transactions, in particular, rose by 892.95%.

And with almost 80% of Vietnam's population remaining unbanked or underbanked, it's no surprise e-wallets have become so popular — they bridge this gap and fulfil consumers' need for quick, easy, and secure transactions and online payments.

Businesses looking to expand in Vietnam will want to consider ZaloPay, one of the country's most popular e-wallets. Integrating ZaloPay into your business gives you access to an extensive customer base of over 14 million users across Vietnam who trust this secure and widely accepted payment method.

Here, we walk you through everything you need to know about the ZaloPay e-wallet, from how to get started with the app to its key features and benefits.

What is ZaloPay?

Founded in 2016, ZaloPay is the financial services arm of Vietnam's tech unicorn, VNG Corporation. It is one of Vietnam's most popular e-wallets, cornering a 53% market share thanks to its over 14 million users. Its focus on user experience and strategic partnerships further solidifies its position as a market leader.

What's the secret to ZaloPay's continued success? Aside from being a standalone e-wallet, it also integrates seamlessly with Zalo, a popular messaging app in Vietnam. This allows Zalo users to pay bills, shop online, and even send money to friends and family straight from the app. With this integration, ZaloPay also taps into Zalo's 77.6 million active users monthly.

While primarily known as an e-wallet, ZaloPay has announced plans to transform itself into an open payment platform.

How does ZaloPay work?

Whether you're a customer or a merchant, it's easy to get started with ZaloPay. Customers only need to download the ZaloPay app, create an account, and link their bank accounts, credit cards, or debit cards to their ZaloPay e-wallet.

l Online shopping. ZaloPay can be integrated with major e-commerce platforms, such as Shopify, for a smooth checkout experience.

For example, including a "Pay with ZaloPay" button alongside other payment options can boost customer conversion rates.
