The Rise of Alternative Payments: How A2A, Digital Wallets, and Real-Time Payments Are Reshaping Global Commerce by 2028

The Tipping Point: Why Alternative Payments Will Dominate by 2028

By 2028, alternative payment methods are projected to account for 58% of all e-commerce transactions globally, according to data from Visa Consulting and Analytics (VCA). That figure represents a fundamental shift in how consumers and merchants move money—one that accelerated sharply after 2020 and shows no signs of slowing.

Supporting milestones paint an equally striking picture. Digital wallets, already the dominant online payment method in much of Asia and Latin America, are expected to be used by 60% of the global population by 2026. Meanwhile, account-to-account (A2A) payments—transfers that move directly from one bank account to another without card networks—are forecast to grow 209% between 2024 and 2029, surpassing 185 billion transactions annually.

The timeline matters. Between 2024 and 2029, the payments industry will undergo a transformation that took card networks decades to achieve. The central question is no longer whether alternative payments will overtake traditional cards, but what economic and technological forces are driving the change—and what risks come with it.

The Two Paths: Government-Backed Infrastructure vs. Private Walled Gardens

The rise of alternative payments is not unfolding uniformly. Two distinct models have emerged, each shaped by political, regulatory, and market forces.

National A2A success stories come primarily from emerging economies where central banks and governments built digital public infrastructure from scratch. India’s Unified Payments Interface (UPI), launched in 2016 and managed by the National Payments Corporation of India, now processes over 10 billion transactions per month. It is free for consumers, instant, and deeply integrated into daily life—from street vendors to e-commerce giants. Brazil’s Pix, created by the Central Bank of Brazil in 2020, achieved similar ubiquity: over 140 million users and 4 billion transactions per month within its first two years. Both systems rely on real-time payments rails and QR codes, and both have dramatically reduced cash dependency.

Private ecosystem dominance tells a different story. In China, Alipay (Ant Group) and WeChat Pay (Tencent) together control more than 90% of the mobile payments market. Their closed-loop systems—combining digital wallets, messaging, and e-commerce—create powerful network effects that make it nearly impossible for external players to compete. In the United States, Apple Pay and PayPal dominate, but they operate atop existing card networks rather than replacing them. Apple Pay still routes payments through Visa and Mastercard rails, while PayPal relies on its own closed merchant network.

Europe occupies a hybrid position. The EU’s Payment Services Directive (PSD2) forced banks to open their APIs to third-party providers, enabling open banking–facilitated A2A payments. Companies like Tink (now part of Visa) and TrueLayer have built platforms that allow consumers to pay directly from their bank accounts at merchants, bypassing cards. Yet adoption remains fragmented across member states due to inconsistent regulatory enforcement and consumer awareness.

"A2A networks thrive in emerging markets with underdeveloped financial infrastructure," says a senior payments analyst at a global consulting firm. "Where credit card penetration is low, digital wallets and direct bank transfers become the default. In mature markets, the inertia of existing card infrastructure and consumer habits slows the shift."

Technology Rails: Real-Time Payments, Open Banking, and QR Codes

Four categories define the alternative payments landscape today: A2A payments, real-time payment (RTP) networks, digital wallets, and open banking–facilitated A2A transfers. Each relies on distinct technology rails.

Real-time settlement is the killer feature. The ability to transfer funds in seconds, 24/7/365, at near-zero marginal cost, has made RTP systems the foundation of most alternative payment innovations. UPI, Pix, and Europe’s SEPA Instant all settle in under 10 seconds. For merchants, that means immediate liquidity and no settlement delays. For consumers, it eliminates the friction of waiting days for bank transfers.

QR codes serve as the universal interface for many of these systems, particularly in retail settings. In China and India, scanning a static or dynamic QR code instantly triggers an A2A payment from the consumer’s wallet or bank account. The simplicity—no card, no terminal, no signature—has driven adoption in segments where traditional card acceptance never reached.

Open APIs enable the next wave. In Europe, open banking regulations require banks to provide read and write access to payment initiation services. A consumer checking out on an e-commerce site can select "Pay by Bank," authenticate via their banking app, and authorize a direct transfer. The merchant receives real-time confirmation. Visa’s own A2A product, launched in 2023, builds on this concept, allowing merchants to accept direct bank account payments without integrating with multiple APIs.

The United States remains an outlier. Lacking a common standard for real-time payments—despite the launch of FedNow in 2023—the market is heavily reliant on private wallets (Apple Pay, PayPal, Venmo) that still process most transactions over card networks. Real-time A2A adoption in the U.S. remains below 5% of e-commerce, compared to over 40% in India and Brazil.

The Unseen Costs: Fraud, Regulatory Chaos, and Fragmentation

The speed and convenience of alternative payments come with trade-offs that the industry is only beginning to address.

Instant, irreversible payments increase vulnerability to authorized push payment (APP) fraud. Unlike card payments, which allow chargebacks, most A2A transactions cannot be reversed once settled. Fraudsters exploit this with phishing attacks, fake invoice scams, and social engineering. In the UK, APP fraud losses exceeded £500 million in 2023, prompting new regulatory mandates requiring banks to reimburse victims. Yet in many other markets, consumer protection remains absent. "While innovations offer speed, convenience, cost-efficiency, they also introduce new challenges," warns a Visa consulting report on fraud risks in A2A payments.

Open banking APIs expand account takeover risks. As more third-party providers gain access to bank accounts through APIs, the attack surface grows. Weak authentication on the merchant side, insecure API endpoints, and insufficient consumer education leave openings for data breaches and credential theft. Regulators in the EU have begun pushing for stronger security mandates under PSD3, but compliance timelines vary.

Consumer protection gaps are structural. When an A2A payment goes wrong—whether due to fraud, a technical glitch, or a merchant failing to deliver goods—the consumer has no equivalent of a credit card chargeback. Some jurisdictions are experimenting with "request to pay" mechanisms that give consumers a window to dispute transactions, but these are not yet standardized globally.

Interoperability failures create friction. A UPI user in India cannot make an A2A payment to a Pix user in Brazil. A European consumer using a Tink-powered payment cannot check out on a U.S. merchant's site that only accepts PayPal. The lack of cross-border A2A interoperability means that for international transactions, card networks and digital wallets remain the default.

Regulatory fragmentation compounds the problem. The EU operates under PSD2 (soon PSD3), India under NPCI rules, Brazil under BCB oversight, and the United States has no unified framework for digital payments. Each regime has different data privacy requirements, liability allocations, and security standards. Merchants operating globally must comply with multiple, sometimes conflicting, regulations—raising costs and slowing adoption.

What the Shift Means for Incumbents

The trajectory is clear: alternative payment methods are not a niche trend but a structural transformation of global commerce. For traditional card networks, the threat is existential in markets where A2A rails bypass their infrastructure entirely. Visa and Mastercard are responding by investing in A2A solutions (Visa’s direct bank payment product, Mastercard’s acquisition of Vocalink) and partnering with wallet providers. But the business model is under pressure: margins on A2A transactions are significantly lower than interchange fees on card payments.

For merchants, the opportunity lies in lower costs and faster settlement. For consumers, the promise is convenience—but only if security and consumer protection keep pace. The next three years will determine whether the alternative payments ecosystem can scale without replicating the fraud and fragmentation problems that have plagued traditional banking.

The global commerce landscape by 2028 will not be one-size-fits-all. It will be a patchwork of national real-time rails, private wallet ecosystems, and open banking bridges. The winners—whether governments, banks, fintechs, or merchants—will be those that navigate the regulatory complexity while earning user trust in an era of irreversible, instant transactions.
