Alternative Payment Methods Explained: Every APM Merchants Should Know (2026)

TL;DR: Cards are no longer the default. Digital wallets now handle 54% of global eCommerce transactions, and alternative payment methods (APMs) as a whole are projected to cover 58% of eCommerce by 2028. For merchants, offering the right APMs is a direct lever on conversion, wrong payment mix at checkout means lost sales, not just missed preference. This guide covers every major APM category: digital wallets, BNPL, bank transfers, real-time rails, local payment methods, crypto, and prepaid. It includes 2026 data, a category-by-category breakdown, and a decision framework for building a payment method stack that fits your markets.

Introduction

The phrase “alternative payment methods” is aging out. When digital wallets alone account for over half of global eCommerce transaction volume, the word “alternative” overstates how fringe these methods are. In most high-growth markets, Brazil, India, the Netherlands, Nigeria, what were once called APMs are now the primary payment infrastructure.

What the category label still captures is useful: these are payment methods that sit outside the traditional Visa/Mastercard card network infrastructure. They include digital wallets, Buy Now Pay Later products, bank transfer schemes (including real-time payment rails and open banking-initiated payments), local and domestic payment methods, cryptocurrency payment gateways, and prepaid instruments.

For merchants managing payment gateways and merchant services across multiple geographies, the question is not whether to offer APMs, it’s which ones, and how to integrate them without multiplying operational complexity.

The State of Alternative Payments in 2026

The data tells a clear directional story:

• Digital wallets: account for 54% of global eCommerce transactions in 2026, up from less than half two years ago (Worldpay Global Payments Report 2026)
• Cards: are projected to fall from 41% to 33% of eCommerce payments by 2026 (TrueLayer)
• BNPL: has seen 70% market share growth between 2021 and 2026, the fastest growth of any APM category
• A2A payment volume: is forecast to reach $850 billion globally by 2026, growing 13% annually
• By 2026, 60% of the global population: is expected to use a digital wallet (Visa)
• APMs overall are projected to handle 58% of eCommerce transactions by 2028 (Visa)
• Cart abandonment: runs at ~70-77% globally, with payment method mismatch a significant driver of that drop-off

The shift is structural, not cyclical. Younger consumers, mobile-first markets, and government-backed real-time payment infrastructure are all reinforcing the same direction: away from card-centric checkout, toward a multi-rail payment environment.

APM Category 1: Digital Wallets

Digital wallets are the dominant APM globally and the largest single payment method category in eCommerce. They store payment credentials, cards, bank accounts, or balance, and enable one-click or biometric checkout without the customer re-entering payment details.

How They Work for Merchants

Merchants integrate digital wallets through their payment gateway or eCommerce platform plugins. The customer authenticates via fingerprint, face ID, or PIN, and the wallet transmits a tokenized payment. Merchant receives settlement through the wallet provider, typically on card rails underneath.

Key Digital Wallets by Region

Pros for Merchants

• Highest global coverage; mandatory for any cross-border payments strategy
• Reduces checkout friction significantly (biometric = under 10 seconds)
• Lower fraud rates via tokenization, no raw card data transmitted to merchant
• Higher authorization rates vs direct card entry (especially for cross-border)

Cons for Merchants

• Wallet fees layer on top of underlying card interchange where applicable
• Consumer data sits with the wallet provider, not the merchant
• Setup and certification required per wallet; complexity scales with market count

APM Category 2: Buy Now, Pay Later (BNPL)

BNPL splits purchases into installments, typically four interest-free payments over six weeks (“Pay in 4”), or monthly plans for larger ticket items. The merchant receives full payment upfront minus a merchant discount rate; the BNPL provider handles the consumer credit relationship.

BNPL now represents 5-6% of global eCommerce, with the fastest growth rate of any APM category. Leading providers, Klarna (850,000 merchant partners, 26 countries), Affirm (377,000 partners, US/Canada), and Afterpay (64 countries), are now embedded in standard payment processing infrastructure across Shopify, WooCommerce, and Magento.

Merchant economics

• Merchant fees: 3.29%-6% + $0.30 per transaction (vs 2-3% for card processing)
• AOV lift: 10-30% reported across merchant studies; Affirm merchants cite up to 85% AOV increase
• Conversion lift: BNPL increases purchase likelihood from 17% to 26%

2026 regulatory note: UK FCA regulation of BNPL as Deferred Payment Credit took effect July 15, 2026, requiring providers to hold FCA authorisation and conduct affordability checks. EU Consumer Credit Directive II brings similar requirements across EU member states. Merchants operating in these markets must verify their BNPL providers are compliant.

APM Category 3: Bank Transfers and Real-Time Payment Rails

Bank transfers move money directly from a buyer’s account to a merchant’s account, bypassing card networks entirely. This category now spans legacy wire transfers, domestic bank transfer schemes, and a new generation of real-time payment (RTP) infrastructure that settles instantly, 24/7.

Real-Time Payments: The Infrastructure Story of 2026

Real-time payment systems backed by central banks or national regulators have moved from niche to dominant in many markets:

• UPI (India): 57% of India’s digital transactions; 49% of global real-time payment volume; 13 billion transactions per month (NPCI, 2026)
• Pix (Brazil): 76.4% adoption across Brazil’s 211 million people; 40% of eCommerce volume; 252 million transactions on a single day in December 2024
• iDEAL (Netherlands): ~92% of Dutch online payments historically; de facto national standard
• BLIK (Poland): Direct bank transfer at checkout; removing BLIK caused one streaming platform’s Polish conversion to fall measurably until restored
• Faster Payments / Pay by Bank (UK): Open banking-enabled A2A payments hit 29.89 million transactions in July 2025; 70% YoY growth 2024–2025
• FedNow / RTP (US): Emerging; A2A could handle ~$200 billion in US consumer-to-business transactions by 2026–2027 (McKinsey)

Why Bank Transfers Matter for Merchant Services

A2A payment processing fees run 0.1%-0.5% versus 0.3%-3% for card payments. For high-volume merchants, this is a significant cost saving. Settlement is near-instant on modern RTP rails, improving cash flow. Fraud risk is structurally lower because bank authentication replaces card number entry.

Pros for Merchants

• Lowest transaction cost of any payment method category
• Instant or near-instant settlement on RTP networks
• No chargebacks on push payment transactions (consumer initiates payment)
• Essential for unlocking conversion in markets where cards are low-penetration

Cons for Merchants

• Cross-border A2A is still fragmented, most RTP networks are domestic
• Consumer UX varies; redirect flows add friction vs one-click wallet checkout
• Not suitable as a standalone merchant services solution in card-dominant markets (US, Japan)

APM Category 4: Open Banking Payments

Open banking uses regulated API access to bank accounts, enabled by frameworks like PSD2 in Europe, FCA open banking rules in the UK, and Section 1033 rules in the US, to let third-party payment providers initiate bank transfers directly at checkout. The result is a “Pay by Bank” button that authenticates through the customer’s banking app with biometrics.

Open banking payments are the fastest-growing bank transfer variant in Europe. The global open banking market is projected to surpass $48 billion in 2026, growing at a 24.8% CAGR. In the UK, open banking payments account for approximately 1 in 13 Faster Payments already.

For merchants, open banking-based payment providers (Truelayer, Token.io, Stripe Financial Connections) offer lower processing costs than cards while maintaining a smooth consumer experience. Variable Recurring Payments (VRPs), open banking-based direct debits, are expanding BNPL-style flexibility to bank rails.

APM Category 5: Local and Domestic Payment Methods

Every major market has dominant local payment instruments that sit outside global card networks. These are not “niche”, in their home market, they are the primary payment method.

Key Local Rails Merchants Must Know

Brazil – Pix: Government-mandated instant payment network. Free for consumers, 24/7, interoperable across every bank and fintech. 93% adult reach, including 60 million people without a credit card. Mandatory for any serious Brazil eCommerce presence.

Netherlands – iDEAL: Bank transfer dominant; direct transfer accounts for 67% of Dutch online payments. iDEAL is the standard integration for any merchant targeting the Dutch market.

Germany – SEPA / Sofort / PayPal: German consumers strongly prefer bank transfers and invoice payment. Card penetration is lower than EU peers; Klarna’s Pay in 30 (effectively BNPL-invoice) has strong adoption here.

Poland – BLIK: Instant bank payment via mobile code. Direct transfer accounts for 70% of Polish online payments. Any cross-border merchant targeting Poland should prioritize BLIK integration.

Mexico – OXXO voucher: Cash-at-convenience-store payment method. Significant share of Mexican consumers outside major cities have no card or bank account. OXXO is the viable checkout path for this segment.

India – UPI: The infrastructure beneath PhonePe, Google Pay India, and Paytm. 85% of India’s digital payments. Non-negotiable for India market entry.

Southeast Asia: GCash (Philippines), GrabPay and Touch ‘n Go (Malaysia), Dana and OVO (Indonesia). Each is the dominant digital payments rail in its country. A regional Southeast Asia strategy requires country-by-country integration.

APM Category 6: Cryptocurrency and Stablecoin Payments

Crypto payments remain a specialist APM category rather than a mainstream checkout option, but they are growing in specific merchant contexts: cross-border B2B payments, high-risk verticals excluded from traditional merchant accounts, and markets with currency instability.

Stablecoins (USDT, USDC) are gaining particular traction as a payment mechanism for cross-border transactions and high-risk payment gateway use cases. For merchants in verticals like iGaming, digital goods, and international services who cannot access standard payment gateways, a crypto payment solution may be a viable path to accepting online payments without traditional merchant account infrastructure.

Merchant considerations: crypto payment processors (CoinPayments, BitPay, NOWPayments) typically charge 0.5-1% per transaction. Volatility risk is mitigated by instant conversion to fiat. Tax and AML obligations apply in all major jurisdictions.

APM Category 7: Prepaid Cards and Vouchers

Prepaid instruments serve the unbanked and underbanked, younger demographics without credit history, and privacy-conscious consumers who prefer not to link bank accounts to merchant platforms.

• Prepaid cards: Loaded with a fixed amount and used like debit at checkout; particularly relevant in Saudi Arabia (33% of online payments via debit/prepaid), Sub-Saharan Africa, and Latin America
• Cash vouchers: OXXO (Mexico), Boleto Bancário (Brazil, now largely replaced by Pix for consumer payments), Paysafecard (Europe). Physical voucher purchased with cash, code entered at online checkout
• Gift cards / store credit: Native to each merchant; relevant for digital goods, gaming, and subscription businesses

For high-risk merchants excluded from standard payment providers, prepaid voucher acceptance (via providers like Paysafe) can be a compliant route to accepting digital payments without a standard merchant account.

APM Integration: A Decision Framework for Merchants

The practical challenge is not understanding APMs, it’s knowing which ones to prioritize without building N separate integrations. A structured approach:

Map your markets: Where are your customers? Each market has a dominant non-card payment method. Entering Brazil without Pix, or the Netherlands without iDEAL, means structurally lower conversion regardless of product quality.

Assess your order value profile: BNPL performs best at $50-$500 AOV. A2A bank transfers are preferred for high-value and recurring transactions. Wallets perform across all AOV ranges but dominate in mobile checkout contexts.

Match to your vertical: Fashion and beauty: Afterpay or Klarna BNPL. Electronics and high-ticket: Affirm or long-form financing. SaaS and subscription: open banking VRPs or ACH. High-risk verticals: specialist high-risk payment gateway with alternative instrument support.

Choose an integration path: Payment orchestration platforms (Adyen, Stripe, Checkout.com, Spreedly) offer single API access to dozens of APMs with intelligent routing, reducing the complexity of managing multiple payment providers simultaneously. For most eCommerce merchants operating across two or more markets, orchestration is the right architecture.

Monitor and optimize: Authorization rates, conversion by payment method, and APM-specific decline rates should be tracked per market. APM mix should be optimized based on actual performance, not assumed preference.

Pros and Cons: APMs vs Cards for Merchants

Pros of offering APMs:

• Unlock conversion in markets where card-only checkout structurally excludes buyers
• Lower transaction fees on A2A and bank transfer rails vs card networks
• Higher AOV on BNPL transactions; fraud risk transfer to BNPL provider
• Competitive advantage in markets where consumer expectation has shifted beyond cards
• Real-time settlement on RTP rails improves merchant cash flow

Cons of offering APMs:

• Integration complexity grows with market count; each APM may require a separate certification or payment provider relationship
• Consumer UX varies significantly across APM categories; redirect flows can introduce friction
• BNPL merchant fees (4-8%) are higher than card processing (2-3%)
• Crypto and prepaid instruments carry compliance obligations
• Not all APMs support subscription or recurring payment models natively

2026 Regulatory Landscape

The regulatory environment for APMs is tightening in all major markets, with implications for merchants:

UK: FCA began regulating BNPL as Deferred Payment Credit on July 15, 2026. Open banking payments framework matures under FCA oversight, with variable recurring payments expanding.

EU: Consumer Credit Directive II brings BNPL under consumer credit regulation across EU member states. PSD3 and the Payment Services Regulation (under finalization in 2026) will extend open banking obligations and fraud liability rules for payment providers.

US: No unified APM regulatory framework; CFPB remains active on BNPL guidance. FedNow and RTP network expansion continues, gradually building the infrastructure for mainstream A2A in the US.

Global: SEPA Instant Payments Regulation mandates instant payment capability across EU banks in 2026, accelerating A2A adoption. Cross-border RTP interoperability remains limited but is an active focus of BIS and G20 payment working groups.

FAQ

What is an alternative payment method (APM)?
An APM is any payment method that falls outside traditional Visa and Mastercard card network transactions. The category includes digital wallets (Apple Pay, PayPal, Alipay), Buy Now Pay Later products, bank transfer schemes, real-time payment rails (UPI, Pix, iDEAL), local payment instruments, cryptocurrency payment gateways, and prepaid cards and vouchers.

Why should merchants offer alternative payment methods?
In most high-growth markets, card acceptance alone is insufficient to capture available purchasing intent. Brazil’s Pix reaches 170 million consumers, including 60 million without a credit card. India’s UPI handles 57% of all digital transactions. Dutch consumers expect iDEAL. A card-only checkout misses these buyers entirely.

How do APMs integrate with existing payment gateways?
Most major payment gateways, Stripe, Adyen, Checkout.com, Worldpay, offer built-in support for a broad range of APMs via their core API or plugins. Payment orchestration platforms provide a single integration layer that dynamically routes transactions across multiple payment providers and APMs based on market, order value, and authorization rate performance.

What is the cheapest payment method for merchants to accept?
Bank transfer via real-time payment rails (Pix, UPI, Faster Payments, A2A) typically carries the lowest transaction cost, often 0.1%-0.5% versus 0.3%-3% for card networks and 4-8% for BNPL. However, availability depends on the geographic market and merchant service setup.

Are alternative payment methods available for high-risk merchants?
Standard APMs, including Klarna, Afterpay, and mainstream digital wallets, do not support high-risk merchant categories such as iGaming, CBD, adult content, and forex trading. High-risk merchants typically require a dedicated high-risk payment gateway provider that may support alternative instruments including crypto payments, SEPA transfers, and specialist acquiring.

What APMs should a US merchant prioritize?
US merchants should prioritize PayPal (71% penetration among US adults), Apple Pay and Google Pay for mobile checkout, and Affirm or Klarna for BNPL. For cross-border payments into specific markets, layer in market-appropriate local APMs: Pix for Brazil, iDEAL for Netherlands, UPI for India. Use a payment orchestration layer to manage integration complexity.

How do cross-border payments work with APMs?
Most real-time payment networks are domestic by design. Cross-border APM strategy typically relies on global digital wallets (PayPal, Alipay, WeChat Pay) or card-funded local wallets as the cross-border-compatible layer. For emerging market entry, local payment aggregators or payment providers with regional coverage are the practical integration path.
