Visa issues digital passports as AI agents overwhelm human commerce
Inside the 4,700% surge that's forcing payment giants to authenticate machines as customers
Last October, while humans shopped for Halloween costumes, something else was shopping too. Artificial intelligence agents hit US retail websites with such force that traffic surged 4,700% in a single year. Not browsing. Buying. Comparing prices across thousands of sites simultaneously. Executing purchases in milliseconds. Making decisions no human authorised them to make.
Visa's response reads like science fiction: the Trusted Agent Protocol, a system for issuing cryptographic passports to software. But this isn't futurism. It's triage. Merchants are drowning in automated traffic they can't identify. Security systems built to catch fraudulent humans are useless against legitimate machines. The payment infrastructure of global commerce - designed around the assumption that someone with a heartbeat initiates every transaction - is breaking.
"We believe the entire payments ecosystem has a responsibility to ensure sellers can trust AI agents as much as they trust their best customers," Jack Forestell, Visa's chief product officer, announced with studied calm. Read between the lines: We're retrofitting the entire financial system because machines have become too economically important to ignore.
The transformation is staggering. The AI agents market rockets from $5.4 billion in 2024 to $50.3 billion by 2030. By 2028, one-third of enterprise software will feature autonomous AI. These aren't assistants. They're independent economic actors with credit cards.
The absurdity of digital citizenship
Picture this: software that exists for three minutes gets a passport more sophisticated than yours.
Visa's protocol assigns cryptographic identities to entities that have no permanent address, no social security number, no mother's maiden name. Each AI agent receives a mathematical signature - timestamps, session identifiers, algorithmic DNA - that merchants verify like border guards checking papers at a checkpoint between the human and machine economies.
The protocol forces AI agents to declare their location. Software must respect geographical boundaries, observe regional restrictions, obey local commerce laws. An algorithm shopping from Singapore can't buy something restricted to UK customers. The machines must follow rules written when commerce meant humans exchanging metal coins.
Here's the beautiful paradox: AI agents are valuable precisely because they're ephemeral. Spawn a thousand in seconds. Scale infinitely. Delete without trace. But Visa demands they maintain persistent identities, build credit histories, establish reputations. We're forcing mercury to hold still for a photograph.
What we're witnessing isn't just technical evolution. It's ontological crisis management. When machines generate enough GDP to matter, they must be governed by trust mechanisms designed for mortals. The protocol doesn't authenticate AI agents - it civilises them, compelling digital entities to perform humanity in a marketplace they're rapidly conquering.
Fraud at the speed of thought
Every security assumption about commerce assumed criminals were human. Humans type slowly. Humans sleep. Humans can only be in one place at once.
AI agents shatter these constraints. They test millions of stolen card numbers faster than humans can blink. They purchase from fifty countries simultaneously without jet lag. They change spending patterns instantly, pivoting from buying server capacity to ordering flowers based on a single line of updated code.
Visa blocked $40 billion in fraud between October 2022 and September 2023 - double the previous year. The surge came from bots operating at inhuman scale, overwhelming defences designed to catch teenagers with stolen credit cards, not distributed intelligences with computational resources rivalling small nations.
"Securing the future of commerce is a shared responsibility," Stephanie Cohen of Cloudflare said, her corporate speak barely masking existential dread. Her company protects millions of websites from bot attacks. Now she must distinguish between good bots with money and bad bots stealing it. Five years ago, this distinction didn't exist. Today, it determines whether commerce survives.
The battlefield has shifted from psychology to mathematics. Forget behavioural analysis - every AI agent's behaviour would seem psychotic to algorithms trained on human patterns. Now it's pure cryptographic warfare. Victory belongs not to whoever acts most human, but to whoever holds the strongest mathematical proofs of identity.
The new world order nobody voted for
Watch the giants scramble. Google builds competing protocols. PayPal launches its own standards. Microsoft, Shopify, Stripe - former rivals now huddle together like survivors planning for an alien invasion. Because that's essentially what this is: a new form of economic life that nobody designed but everyone must accommodate.
Amazon embraces the invasion. During Prime Day 2025, it processed 626 billion AI inference requests. An exabyte of data moved through its systems daily - more information than existed on the entire internet in 2004. The company's 1.3 million sellers use AI to write listings, set prices, manage inventory. Humans have become supervisors of machines that run their businesses better than they could.
Fifty-two percent of enterprises deployed AI agents in production by 2025, according to Google Cloud. Not pilots. Not experiments. Production systems making real decisions with real money. The future isn't coming. It's processing payments.
"We're engaged with Google, OpenAI, and Stripe," Visa told the press, naming competitors like wartime allies. "We're looking to create compatibility." Translation: If we don't coordinate, the incompatible standards we're all desperately building will fragment the global economy into digital fiefdoms where AI agents can't cross borders.
Digital apartheid arrives quietly
Visa promises "minimal changes" and "no-code functionality." Here's what they won't admit: minimal for Amazon means impossible for your local bookshop. The same upgrade that's a rounding error for Walmart could bankrupt a family business.
Watch the divide emerge. Major retailers process thousands of AI queries per second, their infrastructure built for machines that analyse every variable simultaneously. Small merchants can't handle humans who click too fast, let alone software that thinks at light speed.
"AI has eliminated 70-80% of the pain," claims Ryan Klepps of WebPT. He omits the cost of that painkiller. The efficiency gains - perfect orders, instant payments, zero errors - flow exclusively to businesses rich enough to afford them. Everyone else watches the future accelerate away.
Analysts project 40% of B2B transactions will involve AI agents by 2028. For businesses that can't authenticate these digital customers, that's 40% of the economy becoming forbidden territory. We're not witnessing digital transformation anymore. We're watching economic segregation, with software as the new upper class and humans as legacy systems awaiting deprecation.
Tomorrow's economy, drafted today
Visa's protocol isn't technical documentation. It's a constitution written by corporations for a nation of machines. Private companies are defining how artificial entities participate in human civilisation. These aren't democratic decisions. They're infrastructure choices based on profit margins, creating rules that will govern commerce for generations.
2026 brings "the first real season of agentic shopping" - Visa's euphemism for the Christmas when machines outnumber humans at checkout. Not in some distant future. Next year.
Every cryptographic signature issued to an AI agent is an admission of defeat. Each authenticated transaction between machines proves commerce doesn't require consciousness. The protocol Visa built to manage today's crisis might become tomorrow's mechanism for excluding humans from markets that operate beyond our comprehension.
Today, we're teaching machines to shop like humans. Tomorrow, humans might need permission to shop like machines.
The protocol launches on GitHub, available to merchants watching their analytics with mounting horror. For businesses drowning in the surge, it's salvation. For humanity, it's a referendum on our economic relevance, counted in cryptographic signatures.
The machines haven't just arrived. They're customers now. And unlike us, they never sleep, never tire, and never stop shopping.
