Payment Infrastructure Development

🧭 𝗣𝗮𝘆𝗺𝗲𝗻𝘁𝘀 𝗚𝘂𝗶𝗱𝗲: 𝗣𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴, 𝗔𝗰𝗾𝘂𝗶𝗿𝗶𝗻𝗴 & 𝗜𝘀𝘀𝘂𝗶𝗻𝗴 Payments often look simple on the surface — tap, click, approve. Behind every transaction, however, sits a multi-layer financial infrastructure with clearly separated roles, responsibilities, and economics. Here’s a clean breakdown. 🧩 𝗣𝗥𝗢𝗖𝗘𝗦𝗦𝗜𝗡𝗚 — 𝗧𝗵𝗲 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗟𝗮𝘆𝗲𝗿 The technological backbone of payments. 🔹 Transaction authorization & validation 🔹 Message routing (ISO 8583 / ISO 20022) 🔹 Fraud checks & risk scoring 🔹 Clearing & settlement preparation 🔹 Card, wallet, A2A & cross-border flows ➡️ Processing doesn’t face the customer — it connects everyone else. 🧾 𝗔𝗖𝗤𝗨𝗜𝗥𝗜𝗡𝗚 — 𝗧𝗵𝗲 𝗠𝗲𝗿𝗰𝗵𝗮𝗻𝘁 𝗦𝗶𝗱𝗲 Everything that enables businesses to accept payments. 🔹 POS, SoftPOS / mPOS, e-commerce 🔹 Merchant onboarding (KYC / KYB) 🔹 Terminal provisioning & lifecycle (TMS) 🔹 Settlement to merchant accounts 🔹 Chargebacks & dispute handling ➡️ Acquirers translate payments infrastructure into merchant revenue. 💳 𝗜𝗦𝗦𝗨𝗜𝗡𝗚 — 𝗧𝗵𝗲 𝗖𝘂𝘀𝘁𝗼𝗺𝗲𝗿 𝗦𝗶𝗱𝗲 Where payment instruments are born and controlled. 🔹 Debit, credit, prepaid & virtual cards 🔹 Tokenization & lifecycle management 🔹 Balance, limits & real-time authorization 🔹 Customer support & disputes ➡️ Issuers own the customer relationship and credit risk. 🔁 𝗖𝗮𝗿𝗱 𝗧𝗿𝗮𝗻𝘀𝗮𝗰𝘁𝗶𝗼𝗻 𝗙𝗹𝗼𝘄 (𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝗶𝗲𝗱) 𝗔𝘂𝘁𝗵𝗼𝗿𝗶𝘇𝗮𝘁𝗶𝗼𝗻 → 𝗖𝗹𝗲𝗮𝗿𝗶𝗻𝗴 → 𝗦𝗲𝘁𝘁𝗹𝗲𝗺𝗲𝗻𝘁 ⏱️ Authorization: real-time (~2 seconds) 📦 Clearing: batch, end of day 💸 Settlement: T+1 / T+2 Approved ≠ settled — timing matters. 💰 𝗪𝗵𝗼 𝗘𝗮𝗿𝗻𝘀 𝗪𝗵𝗮𝘁? A typical $100 card transaction: 🔹 Merchant pays MDR (~2–3%) 🔹 Issuer earns the largest share (interchange) 🔹 Acquirer & network take smaller, fixed slices ➡️ Economics explain why issuers dominate cards — and why A2A keeps growing. 🧩 𝗗𝗶𝗴𝗶𝘁𝗮𝗹 𝗣𝗮𝘆𝗺𝗲𝗻𝘁𝘀 & 𝗕𝗮𝗻𝗸𝗶𝗻𝗴 𝗘𝗻𝗮𝗯𝗹𝗲𝗿𝘀 Between processing, acquiring, and issuing sits another critical layer — enablers. Not replacing banks, networks, or processors. But connecting, orchestrating, and scaling them. 🔹 White-label issuing & processing 🔹 BIN sponsorship & compliance frameworks 🔹 Payment hubs & orchestration layers 🔹 API-driven connectivity across rails 🔹 Faster time-to-market for banks & fintechs ➡️ Enablers turn complex, regulated infrastructure into deployable platforms. 🧠 𝗧𝗵𝗲 𝗸𝗲𝘆 𝗶𝗻𝘀𝗶𝗴𝗵𝘁 Processing, acquiring, and issuing are not competitors. They are complementary layers of the same system. 𝗣𝗮𝘆𝗺𝗲𝗻𝘁𝘀 𝗮𝗿𝗲 𝗻𝗼𝘁 𝗮 𝗳𝗲𝗮𝘁𝘂𝗿𝗲. 𝗧𝗵𝗲𝘆 𝗮𝗿𝗲 𝗮𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲. Design the layers right — and everything on top scales.

Payments have evolved from paper and plastic to APIs and orchestration - giving rise to a new breed of players that simplify the complexity and connect the dots behind the scenes. Here's how we got here. 𝟭. 𝗜𝗻 𝘁𝗵𝗲 𝗽𝗿𝗲-𝟭𝟵𝟵𝟬𝘀 𝗲𝗿𝗮, banks owned the entire payments value chain -acquiring, processing, settlement. Merchant onboarding was complex, and domestic clearing systems ruled. 𝟮. 𝗧𝗵𝗲 𝗿𝗶𝘀𝗲 𝗼𝗳 𝗲-𝗰𝗼𝗺𝗺𝗲𝗿𝗰𝗲 in the late 1990s changed everything. Players like PayPal and Authorize made online payments possible, while banks began exiting the acquiring space or partnering with processors to keep up with demand. 𝟯. 𝗕𝗲𝘁𝘄𝗲𝗲𝗻 𝟮𝟬𝟬𝟬 𝗮𝗻𝗱 𝟮𝟬𝟭𝟬, specialized gateways and regional wallets began to scale, offering merchants greater flexibility and control. The launch of SEPA in Europe marked a push toward payment harmonization, while non-bank players started building infrastructure that bypassed traditional acquiring models altogether. 𝟰. 𝗧𝗵𝗲 𝘀𝗵𝗶𝗳𝘁 𝘁𝗼 𝗔𝗣𝗜-𝗱𝗿𝗶𝘃𝗲𝗻 𝗶𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 transformed payments from siloed systems into modular, developer-friendly tools. Merchant onboarding became faster, integrations simpler, and innovation more scalable. Open Banking regulations enabled direct access to bank data, while new credit models redefined consumer behavior. Payments evolved into a flexible, programmable layer of the digital economy. 𝟱. 𝗧𝗼𝗱𝗮𝘆, we’re in the age of seamless integration. Payments are embedded in everything - from ride-hailing apps to SuperApps. Real-time rails like SEPA Instant, UPI and PIX are live. CBDCs are in pilot. However, as payment ecosystems grow more fragmented - with new methods, regional schemes, compliance layers, and fraud risks -complexity has become a major bottleneck for merchants, fintechs, and even banks. Integrating multiple providers, maintaining uptime across systems, and ensuring regulatory compliance isn't just costly - it's unsustainable without the right foundation. This is where a new breed of infrastructure players like 𝗔𝗸𝘂𝗿𝗮𝘁𝗲𝗰𝗼 fit in - offering the tools to simplify complexity and still retain control. • 𝗪𝗵𝗶𝘁𝗲-𝗹𝗮𝗯𝗲𝗹 𝗽𝗮𝘆𝗺𝗲𝗻𝘁 𝗴𝗮𝘁𝗲𝘄𝗮𝘆𝘀 let banks, PSPs, and fintechs launch their own branded platforms fast - without building from scratch. • 𝗣𝗮𝘆𝗺𝗲𝗻𝘁 𝗼𝗿𝗰𝗵𝗲𝘀𝘁𝗿𝗮𝘁𝗶𝗼𝗻 enables merchants to route transactions dynamically across multiple acquirers, reducing costs and failed payments while improving UX. • 𝗕𝗮𝗻𝗸𝘀 can embed API-driven acquiring services into their offerings without the burden of a full-scale tech overhaul. In a world where growth brings fragmentation, the real challenge isn’t enabling payments - it’s managing them. The advantage will lie with infrastructure that can unify complexity, adapt in real time, and scale across borders without adding friction.

The sad reality about payments is that they have become so much commoditised that the traditional acquiring model no longer holds. What was once a service merchants paid a premium for i.e. card acceptance, infrastructure, compliance, is now expected to 𝘫𝘶𝘴𝘵 work. And to work 𝘧𝘰𝘳 𝘭𝘦𝘴𝘴. Large merchants have the power to negotiate acceptance fees down to razor-thin margins, sometimes to the point where the cost of acceptance is almost negligible and barely commercially viable for acquirers. Meanwhile, smaller merchants, many of whom have no dedicated payments resource, often pay more without realising the alternatives 𝘶𝘯𝘵𝘪𝘭 they outgrow their current provider! In 2025, acceptance is expected, reliability is assumed, and merchants, particularly digital-native or omni-channel businesses don’t perceive value in the transaction alone. Pricing pressure has intensified, margins have collapsed, and the traditional acquirer-merchant relationship has fundamentally changed. Traditional acquirers once controlled the core infrastructure of payments but today many risk fading into the many interchangeable components of a stack they neither designed nor meaningfully influence. Platforms like Shopify, Toast, and Stripe rewrote the rules by embedding payments into tools merchants actually use i.e. CRMs, booking systems, storefronts etc... The market now expects the infrastructure to do more: ⚪Connects payments with data ⚪ Work across channels and payment methods ⚪Integrate loyalty, fraud, and customer experience... ... all whilst remaining modular and flexible, 𝘳𝘢𝘵𝘩𝘦𝘳 𝘵𝘩𝘢𝘯 prescriptive or monolithic. It’s no longer 𝘫𝘶𝘴𝘵 about access or integration. It’s about giving merchants ownership and control with autonomy, balanced with the transparency to understand the performance across their stack, the agility to adapt, and the intelligence to optimise and grow their operations. The infrastructure itself should feel 𝘪𝘯𝘷𝘪𝘴𝘪𝘣𝘭𝘦. What matters is the 𝐯𝐚𝐥𝐮𝐞 it enables, how that value is delivered, and the quality of relationship it fosters. The impact is driven by relevance, adaptability, and operational performance. Today, much of the innovation [𝘢𝘯𝘥 𝘵𝘩𝘦 𝘳𝘦𝘢𝘭 𝘸𝘪𝘯𝘯𝘦𝘳𝘴 ] are emerging where the infrastructure is: 🔹 Vertical by design ↪️ Native to merchant operations 🔹 Contextual by default  ↪️ Orchestrating smarter flows 🔹 Embedded in the way merchants actually operate ↪️ Creating relevance, not dependency #PaymentExperts, in that context, who do you think is leading the acquiring space these days? 🎤 --- 𝐍𝐞𝐞𝐝 𝐡𝐞𝐥𝐩 𝐰𝐢𝐭𝐡 𝐲𝐨𝐮𝐫 𝐩𝐚𝐲𝐦𝐞𝐧𝐭 𝐨𝐫 𝐩𝐫𝐨𝐝𝐮𝐜𝐭 𝐬𝐭𝐫𝐚𝐭𝐞𝐠𝐲?  👉🏽Let's talk: intro@paypr.work 𝐋𝐨𝐨𝐤𝐢𝐧𝐠 𝐟𝐨𝐫 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐥𝐞𝐚𝐫𝐧𝐢𝐧𝐠 𝐫𝐞𝐬𝐨𝐮𝐫𝐜𝐞𝐬? 👉🏽Check out our unique hub: https://lnkd.in/dKsmxGnT 🖇️ Follow Paypr.work [ˈpeɪpəwəːk] for more weekly #paymentinsights #paymentinfographics

In this episode of the Wrap Up Podcast, I’m joined by Matt Marcus, CEO, and Sam A., CTO of Modern Treasury. We break down how Modern Treasury evolved from an API-first bank payments platform into a full-stack, multi-rail infrastructure provider supporting ACH, wires, RTP, FedNow, and stablecoins under a single unified ledger. We discuss: - How Modern Treasury’s new integrated payments product enables companies to launch in days - Why compliance ownership is shifting back to infrastructure providers - The role of AI in engineering productivity, compliance workflows, and fraud detection - Lessons from Synapse and the importance of immutable, double-entry ledgers - What companies must assess when choosing an infrastructure partner - Why instant, cheap, and usable payments will define the next decade This conversation goes deep into payment stack architecture, embedded finance evolution, stablecoin integration, and what the future of money movement actually looks like at scale. If you operate in fintech, treasury, embedded finance, or payments infrastructure, this episode unpacks where the rails are heading — and what it takes to build on top of them.

Cash dies when people stop trusting it. Digital money dies when the internet goes down. India found a way to solve both problems. India created a government-backed digital currency that works without the internet. This latest research on India's CBDC foray reveals how this changes everything. India's digital currency pilot is quietly becoming the world's most sophisticated payment experiment. With 5 million consumers and 420,000 merchants already onboard, here's what's reshaping the future of money: ↳Offline-first innovation: Three breakthrough models ensuring payments work during network blackouts - hardware tokens for security, software wallets for accessibility, and hybrid systems leveraging telecom networks. This isn't just about India's connectivity challenges; it's about building resilient infrastructure for the entire developing world. ↳Programmable money revolution: Smart contracts enable unprecedented control - parents setting geographic limits on children's spending, governments ensuring subsidies reach intended beneficiaries, and businesses creating conditional loyalty rewards. The Odisha Subhadra scheme targeting 1 crore women could be the first major real-world test. ↳Cross-border transformation: The $190T global payments market (projected $290T by 2030) desperately needs alternatives to the nostro-vostro maze. India's participation in BIS Project Nexus suggests we're moving toward universal CBDC networks that could eliminate correspondent banking inefficiencies. My perspective after 20 years of building payment systems across 4 continents: The technical innovations are impressive. But I'm watching three critical tensions: ↳Privacy vs. Transparency: CBDCs offer perfect audit trails for fraud prevention but risk creating financial surveillance states. The winning implementations will use zero-knowledge proofs and selective disclosure, giving regulators what they need without exposing everything. ↳Innovation vs. Adoption: FinTech companies drove UPI's success through cash-backed incentives. But current CBDC pilots lack compelling commercial models for intermediaries. Without clear monetization paths, ecosystem players won't drive adoption. ↳Global vs. Local: Interoperability sounds great until you face regulatory fragmentation. The real challenge isn't standards - it's regulatory harmonization across jurisdictions with different privacy laws, KYC requirements, and monetary policies. For builders and operators: Focus on solving the "last mile" problems - user experience during network failures, seamless fiat-to-CBDC conversion, and most critically, the business case for every stakeholder in your ecosystem. What's your take? Will programmable money create more opportunities or risks? And how do we balance financial inclusion with privacy protection? Share your thoughts - the decisions we make now will define the next decade of global finance.

The payments stack is quietly being rebuilt — and the latest move from Visa shows how fast that transformation is accelerating. Visa Intelligent Authorization is a new capability on the Visa Acceptance Platform that allows acquirers to modernize payment processing through a single API integration, capable of processing transactions across multiple card networks. On the surface, this looks like an infrastructure upgrade. But the implications for the payments ecosystem are far bigger. 1️⃣ Payments infrastructure is becoming “API-first.” Instead of banks or acquirers building and maintaining their own authorization stacks, they can plug into modular infrastructure through a single API. This significantly reduces the cost and complexity of modernization. 2️⃣ Orchestration is becoming the new battleground. As payment flows become more complex — with wallets, A2A, stablecoins and AI-driven commerce entering the mix — the ability to intelligently route and authorize transactions across networks will be a key differentiator. 3️⃣ Lower barriers for ecosystem innovation. Fintechs, PSPs and software platforms can integrate once and access multiple payment rails, accelerating innovation for merchants and enabling new commerce experiences without rebuilding core infrastructure. 4️⃣ Networks are evolving into platforms. Moves like this reinforce a broader trend: payment networks are no longer just processing transactions — they are becoming programmable infrastructure layers that others build on. For those of us working in payments, this shift is fascinating. The industry is moving from “card networks” to “payments platforms.” And when infrastructure becomes programmable, the real innovation happens at the edges — where fintechs, merchants, developers and partners build the next generation of commerce experiences.

2026 may be the year AI agents get their first native economic infrastructure — and stablecoins are emerging as the settlement rails. Traditional payment systems were designed for human authorization flows, not autonomous machine actors. Agentic commerce introduces very different requirements: • Micropayments • Programmable settlement • Delegated spending controls • Machine-to-machine interoperability That is why recent developments matter: • Tempo launched mainnet alongside the Machine Payments Protocol (MPP), enabling programmable payment sessions for AI agents. • Coinbase ’s x402 is advancing a model where payments can be embedded directly into HTTP requests. • New agent marketplaces are beginning to test autonomous discovery, service consumption, and machine-to-machine settlement. This does not mean the model is complete. Identity, agent governance, liability models and compliance controls still need to mature. But the direction is becoming clearer: Machine-to-machine commerce is moving from concept to infrastructure. In my view, the question is no longer whether autonomous agents will transact. It is whether today’s payment architecture is ready when they do.

Most issuer processors say they have “robust infrastructure.” We learned the hard way what that really means. Years ago, when we were building our first company (Privacy.com), we worked with several of the most established legacy processors and kept hitting the limits as we scaled: 🕒 scheduled downtime 📊 messy settlement reporting 🐢 years for basic feature releases 🙈 consistently lackluster support It was painful. And it became clear: if we wanted a highly performant and resilient platform, we’d have to build it ourselves. That’s how Lithic started. Our mission to transform payments and banking infrastructure has always been personal for us. In his latest post, my cofounder Jason breaks down how we built a platform that delivers: ✅ 99.999%+ authorization uptime 💳 Billions in monthly volume 🏗️ 100+ programs The difference is in the details: ⚡️ Multiple redundant private circuits into Visa, Mastercard, and the Federal Reserve. The entire internet could be down, and we will continue to route and process transactions. 💪 N+3 redundancy across fully independent data centers 🧠 Real-time auth intelligence, that enables better fraud detection, and flexible ledger architecture We built with intentionality because we’d seen firsthand what breaks as you scale. The architectural and choices we made (hybrid cloud, physical connectivity, Rust/DynamoDB stack) are about removing the constraints that make modern card issuing processing so difficult to scale reliably. If you’re evaluating payment infrastructure, Jason’s post lays out some key questions: 💭 Are they directly connected to the networks or routing through gateways? 🌐 Do they use dedicated fiber or depend on the public internet? ⚙️ Can their architecture support real-time processing and next-gen account types? The choice is simple: 👉 Build on 2025 infrastructure or 🚧 Get stuck with 2015 limitations And if you’re heading to Money20/20 and made it this far, come say hi! 👇 Full breakdown in Jason’s post in comments.

🚨 Final Recap: 𝟐𝟓 𝐘𝐞𝐚𝐫𝐬 𝐨𝐟 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞, 𝐎𝐫𝐜𝐡𝐞𝐬𝐭𝐫𝐚𝐭𝐢𝐨𝐧 & 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞 by DEUNA👇 Over the past two decades, the payments ecosystem has undergone three fundamental shifts: → From static, rigid infrastructure → To programmable orchestration → To real-time, reasoning intelligence This post brings the full transformation together in a single strategic framework. — 𝐏𝐚𝐫𝐭 1 — 2000s: 𝐓𝐡𝐞 𝐋𝐞𝐠𝐚𝐜𝐲 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐄𝐫𝐚 🔹 Characteristics: Merchants relied on single PSP setups, limited routing, and siloed data. Fraud was handled manually. Reconciliation was slow and error-prone. 🔹 Key Constraints: → No fallback logic or retry mechanisms → No fraud orchestration or dynamic controls → Data scattered across PSPs, acquirers, and tools 🔹 Business Impact: → Failed transactions = lost revenue → Limited visibility into payment performance → No ability to optimize or adapt in real time ➡️ Payments were operational—but not strategic. — 𝐏𝐚𝐫𝐭 2 — 2010s: 𝐓𝐡𝐞 𝐎𝐫𝐜𝐡𝐞𝐬𝐭𝐫𝐚𝐭𝐢𝐨𝐧 𝐋𝐚𝐲𝐞𝐫 𝐄𝐦𝐞𝐫𝐠𝐞𝐬 🔹 The Evolution: The rise of payment orchestration decoupled logic from providers, enabling intelligent routing, backup PSPs, tokenization, and unified reporting. 🔹 Technical Capabilities Introduced: → Routing engines (BIN, amount, geography) → Automated transaction recovery → Real-time fraud controls and smart 3DS → Centralized reconciliation and compliance → Token vaulting and PSP abstraction 🔹 Strategic Benefits: ✅ Increased approval rates ✅ Improved cost efficiency ✅ Faster market expansion ✅ Better governance and reporting ➡️ Payments became a modular, resilient system for growth. — 𝐏𝐚𝐫𝐭 3 — 2020s: 𝐓𝐡𝐞 𝐀𝐠𝐞 𝐨𝐟 𝐀𝐠𝐞𝐧𝐭𝐢𝐜 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐈𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞 🔹 The Shift: We are now entering a phase where payments infrastructure doesn’t just execute—it reasons. 🔹 Why This Matters: Despite orchestration, over $300B is lost annually due to missed opportunities, fragmented data, and reactive operations. 🔹 What Defines Agentic Payments Intelligence: 1️⃣ Unified, intelligent data layer → Structures commerce, payments, fraud, and behavioral data into a single, actionable foundation. 2️⃣ Context-aware reasoning engine → Detects issues, trends, and opportunities based on business context—not static rules. 3️⃣ Real-time execution framework → Automates action: retry logic, provider switching, checkout optimization, and more. ➡️ Payments now serve as a strategic decisioning engine—not just infrastructure. — The future of commerce will belong to those who evolve with the stack. From infrastructure → to orchestration → to intelligence. Source: DEUNA ► Subscribe to 𝐓𝐡𝐞 𝐏𝐚𝐲𝐦𝐞𝐧𝐭𝐬 𝐁𝐫𝐞𝐰𝐬: https://lnkd.in/g5cDhnjC ► Connecting the dots in payments... | Marcel van Oost

Back in 2015, I made a mistake that many founders still make today: I thought payments were just a commodity. Connect a provider, then forget about it, right? Wrong. After building Rappi and now Yuno, I learned that the payments landscape has evolved dramatically. → Multiple payment processors needed per country → New payment methods launching every month → Complex approval rate optimization → Fraud management → Local regulations in each market As a result, we see: → Companies losing money due to suboptimal payment setups → Opportunities missed because of limited payment options → Resources wasted on complex integrations A recent example: One of our merchants accepted an alternative payment method with a 40% conversion. "That's normal," they said. Their provider told them so. We ran an A/B test with a different provider. The result: 70% conversion. That's the difference a payment orchestrator/partner can make - we: - Ask the right questions - Run the right tests - Optimize what others assume is "normal" Payment infrastructure can be either your biggest limitation or your strongest competitive advantage. The choice is yours.
