What Are Payment Methods? Types, Examples & Guide (2026)

Payment methods are the mechanisms buyers use to transfer funds at checkout — including cards, digital wallets, real-time payment rails, BNPL, and bank transfers — each with distinct adoption rates, fraud profiles, and settlement timelines.

If you're expanding into Southeast Asia and only offering cards at checkout, you're likely losing sales before they happen. Across much of the region, consumers pay with local digital wallets and real-time payment rails — not international card networks. Knowing which payment methods your buyers actually use is the first step to closing that gap.

This guide covers:

• The six main types of payment methods and how each works — including their chargeback risk profiles

• Which local payment methods dominate each Southeast Asian market, and which to prioritize first

• Why merchants consistently choose the wrong payment mix — and how to avoid the same mistakes

• How to support multiple local options without building a separate integration for every country

Key Takeaways

1. Payment methods fall into six categories: cards, digital wallets, online banking, real-time payments, BNPL, and cash payments — each with a distinct chargeback risk level and settlement timeline.

2. Southeast Asian consumers rely heavily on local wallets and real-time payment rails — not international cards — making local payment method coverage critical for regional conversion.

3. Each major Southeast Asian market has its own dominant method: PromptPay in Thailand, QRIS in Indonesia, PayNow in Singapore, GCash in the Philippines, Touch 'n Go eWallet in Malaysia, and ZaloPay in Vietnam.

4. Three mistakes drive most payment method failures in Southeast Asia: defaulting to cards, treating the region as one market, and equating method count with coverage quality.

5. Merchants can access 300+ payment methods across 200+ markets through a single API integration with Antom.

What Are Payment Methods?

Payment methods are the full set of instruments by which buyers initiate and complete fund transfers at checkout — each with its own authorization flow, settlement cycle, and regional adoption pattern that determines its role in a given market.

Which methods you offer determines whether buyers complete a purchase or leave. In markets where a specific wallet or bank rail is the dominant payment habit, a missing option at checkout is enough to lose the sale entirely.

According to Baymard Institute's checkout usability research, 13% of online shoppers globally abandon their carts when their preferred payment method isn't available. That figure is a global average weighted toward high-card-penetration markets. In Southeast Asian markets where card ownership among the online-active population is substantially lower, the share of buyers who encounter no usable option at a card-only checkout runs higher still.

The 6 Main Types of Payment Methods

Online payment methods divide into six categories, each with distinct processing mechanics, chargeback exposure, and regional adoption rates that determine which options belong at your checkout.

Cards remain the global default and are non-negotiable for any merchant selling internationally. They also carry the highest chargeback exposure of any payment type: buyers can open disputes up to 120 days after a transaction through their issuing bank, and merchants bear the initial financial risk of those disputes.

Digital wallets are the dominant payment type across Southeast Asia. They operate on closed-loop account systems — a buyer's GCash balance can only be spent where GCash is accepted. Because wallets are authenticated push payments, they carry substantially lower chargeback exposure than cards. There's no automatic cross-wallet interoperability, which means merchants need to support each wallet that matters in a given market.

Online banking connects buyers directly to their bank account without a card intermediary. Adoption is highest in markets with strong banking infrastructure but relatively lower card usage — Malaysia (FPX), the Netherlands (iDEAL), and Poland (BLIK) are good examples.

Real-time payments run on government-backed national payment rails and settle in seconds. Because these transfers are final and irreversible, they carry zero chargeback exposure for merchants — no dispute window exists once the acquiring bank confirms settlement. They're the fastest-growing payment type across Southeast Asia.

BNPL lets buyers defer or split payment while merchants receive the full amount upfront (minus fees). In Southeast Asia, BNPL usage is concentrated in higher-ticket categories and younger demographics, particularly in the Philippines (BillEase) and Indonesia (Kredivo). Risk allocation varies by provider — confirm dispute terms before integrating.

Cash payments serve unbanked buyers and trust-sensitive scenarios. The buyer completes an order online, receives a reference code, and pays at a convenience store counter. Because payment is confirmed before fulfillment, there is no chargeback exposure.

Local Payment Methods in Southeast Asia: A Country-by-Country Guide

Southeast Asia's six major e-commerce markets each run on distinct local payment rails — PromptPay in Thailand, QRIS in Indonesia, PayNow in Singapore, GCash in the Philippines, Touch 'n Go eWallet in Malaysia, and ZaloPay in Vietnam.

The fragmentation is partly structural. The region spans countries with different banking systems, regulatory frameworks, and mobile adoption timelines. In markets where a large share of the population remains underbanked, local wallets and government-backed QR rails have filled the gap that card networks never fully covered.

The table below highlights local Payment Methods payment methods across select key Southeast Asian markets.

The Philippines

GCash has over 94 million users, spanning a large portion of the country's internet-active population. Maya is another widely used digital wallet in the market. Merchants entering the Philippines typically need to support both to reach a broad share of local buyers.

Indonesia

QRIS is the national QR standard in Indonesia, set and operated by Bank Indonesia. It allows buyers to pay by scanning the same code whether they're using a bank app or a supported wallet.

QRIS and GoPay are not interchangeable. QRIS covers bank-app-initiated payments across the national rail, while GoPay operates within the Gojek super-app ecosystem and reaches a distinct user base. Other widely used wallets in Indonesia include DANA and OVO.

Thailand, Singapore, Malaysia, Vietnam

In Thailand, PromptPay is the national real-time payment rail, operated by the Bank of Thailand and supported by all major banks. TrueMoney Wallet is another commonly used option for buyers who prefer a pre-loaded balance.

In Singapore, PayNow is a widely used local payment method, alongside card payments (Visa/Mastercard).

In Malaysia, Touch 'n Go eWallet has over 17.8 million users. FPX is another common option for buyers who prefer direct bank account authorization.

In Vietnam, ZaloPay is a widely used standalone wallet. VietQR is a real-time payment option for buyers who prefer paying directly from their bank account.

BNPL in Southeast Asia

BNPL in Southeast Asia has developed distinct characteristics shaped by local consumer credit behavior. BillEase in the Philippines and Kredivo in Indonesia are tied to local consumer credit behavior and regional credit scoring infrastructure.

Why Merchants Choose the Wrong Payment Methods in Southeast Asia

Most merchants enter Southeast Asia with a payment strategy built for their home market. That strategy fails — not because Southeast Asia is unusually complex, but because three assumptions that hold in card-dominant markets do not hold here.

Mistake 1: Cards First

Cards dominate checkout in many markets outside Southeast Asia, including North America and Western Europe. Merchants entering the region often extend this assumption to Southeast Asia — building a card-first checkout and treating wallets or real-time rails as supplementary. In most Southeast Asian markets, this inverts the actual local payment hierarchy. Mobile wallets and real-time rails are the primary checkout behavior; cards fill a secondary role. A card-first checkout is structurally leaving out the majority of local buyers in markets like Indonesia and the Philippines.

Mistake 2: One Southeast Asia, One Checkout

"Southeast Asia payment support" is not a single checkout configuration. It is six separate payment ecosystems with minimal overlap between them. A checkout built for Singapore's PayNow does not cover Thailand's PromptPay. A configuration optimized for Malaysia's FPX does not extend to Indonesia's QRIS ecosystem. Merchants who configure a single "Southeast Asia checkout" in practice cover zero markets well — they build the appearance of regional coverage without the conversion results.

Mistake 3: More Methods = Better Coverage

Adding every available payment method does not improve coverage — it creates checkout clutter. In each Southeast Asian market, one or two methods account for the large majority of local checkout completions. Supporting the dominant method per market delivers more conversion improvement than supporting five secondary methods. The goal is depth of coverage in each market, not the longest possible payment option list.

How to Choose the Right Payment Methods for Your Online Business

The right payment method mix depends on three factors: the markets you sell into, your transaction model, and your customers' device behavior.

Quick Reference: Match Your Business Type to Payment Priorities

The 3-Layer Payment Method Selection Model

Layer 1 — Market Fit: Start with the country table above. For each market you enter, identify the primary method and at least one secondary option. Entering Indonesia without QRIS, or the Philippines without GCash, means accepting a structural conversion gap from day one.

Layer 2 — Transaction Architecture: One-time purchases need the broadest local method coverage. Subscription and recurring billing add a second requirement: tokenized payment — stored credentials that allow repeat charges without re-authentication. Not all local wallets support tokenization. Confirm support before building a subscription flow on a local wallet. Antom supports both one-time and tokenized payment across its integrated methods.

Layer 3 — Device Behavior: The dominant payment methods across Southeast Asia — GCash, QRIS, PromptPay — are all built around smartphone interactions: QR scanning or in-app authorization. Checkout flows not optimized for mobile wallet redirect will underperform regardless of which methods you offer.

Platforms like Antom allow merchants to activate payment methods per market through configuration rather than separate integrations, making it practical to apply this model across all six core Southeast Asian markets simultaneously.

Payment Method Selection Checklist

Before enabling any payment method at checkout:

• Does this method hold top-2 checkout share in my target market?

• Is settlement available in the required currency (local currency or USD)?

• What is the chargeback exposure — does the buyer carry a dispute right, or is settlement final and irreversible?

• Does this method support tokenization for recurring or subscription billing?

• Has the integration been fully tested in sandbox before production go-live?

• What are the PCI DSS compliance implications of this integration path?

• Does the provider's settlement cycle align with my cash flow requirements?

How to Accept Local Payment Methods with a Single Integration

Integrating local payment methods market by market requires separate API connections, compliance reviews, and settlement accounts for each provider — unless you use a payment aggregator that handles the entire network through one integration.

Here's how the process works with a single-integration approach:

Step 1: Identify the payment methods you need

Use the Southeast Asia country table and the Payment Method Selection Checklist above to build your required method list per market. Be specific — "Indonesia" isn't a payment method; QRIS, DANA, and GoPay are.

Step 2: Choose your integration path

Two primary approaches:

• Hosted Checkout Page: A pre-built checkout interface that handles payment UI, redirect flows, and local wallet integrations on your behalf. Lower development lift, faster go-live. The practical starting point for most SME merchants.

• Direct API Integration: Full programmatic control over the checkout experience. Higher development investment, but allows custom UX and deeper platform logic. Better suited for merchants with dedicated engineering resources.

Step 3: Connect once, activate by market

A single API connection to Antom gives merchants access to 300+ payment methods across 200+ markets. Payment methods are activated per market through configuration — no rebuild required for each country. New payment methods added to the Antom network become available to existing integrations at minimal incremental cost.

Step 4: Test before going live

Use Antom's sandbox environment to validate payment flows, redirect behavior, and error handling before launching in each market. Local wallet integrations in particular can vary significantly in redirect behavior and error state handling — testing before go-live avoids silent failure at checkout.

FAQ: Payment Methods

What is the most widely used payment method online?

Cards (credit and debit) are the most widely used online payment method globally, led by Visa and Mastercard. In mobile-first markets across Southeast Asia and East Asia, however, digital wallets and real-time payment rails often exceed card usage — making "most used" highly dependent on geography.

What is the difference between a digital wallet and a credit card?

A credit card draws from a credit line issued by a bank and settles through a card network. A digital wallet holds a stored balance within a closed-loop app — the buyer loads funds into the wallet and spends from that balance. Digital wallets typically settle faster, carry different fee structures, and are more deeply embedded in local mobile ecosystems across Southeast Asia.

Do local payment methods affect checkout conversion rates in Southeast Asia?

Yes. When buyers reach checkout and don't see their preferred payment method, they leave. In markets where a single wallet dominates consumer behavior — GCash in the Philippines (94M+ users) or Touch 'n Go eWallet in Malaysia (17.8M+ users) — not supporting it creates a structural conversion gap that no checkout UX improvement can compensate for.

How many payment methods should an online store offer?

For a single-country Southeast Asian launch, a practical minimum is: one global card option, the market's primary local wallet or real-time rail, and one backup method. For a multi-country rollout, each market needs its own stack. In Thailand, that means PromptPay and one major wallet. In Indonesia, QRIS plus DANA or GoPay. In the Philippines, GCash and Maya. A single integration that activates methods per market is more scalable than building each connection individually.

Why do cards perform poorly in Southeast Asia compared to other markets?

Cards underperform in several Southeast Asian markets for two reasons. First, card penetration among the online-active population is substantially lower than in markets where cards are the dominant payment method — a card-only checkout excludes the majority of local buyers in markets like Indonesia and the Philippines. Second, cross-border card transactions face additional friction from fraud screening rules applied by issuing banks to unfamiliar merchant locations. Local real-time rails and digital wallets face no such friction: they operate within domestic ecosystems, so a local buyer paying through GCash or PromptPay completes a domestic transaction regardless of where the merchant is registered.

Which payment method type carries the lowest fraud and chargeback risk for online merchants?

Real-time payment rails carry the lowest chargeback exposure for online merchants. Transactions are irreversible by design — once a PromptPay or QRIS payment settles, no buyer dispute window exists. Digital wallets are the second-lowest-risk category: authenticated push payments with limited dispute windows. Cards carry the highest chargeback exposure, as Visa and Mastercard rules give buyers up to 120 days to open disputes after a purchase.
