Mastercard secretly did something big: the payment industry may face a major change

Mastercard has recently done something quite imaginative. Last night, they officially launched a payment system called Agent Pay for Machines, abbreviated as AP4M, specifically for AI agents.

Simply put, it allows AI programs to pay and receive money on their own, without human confirmation at any stage.

Why is this needed?

Because the way AI works has changed. In the past, AI only helped generate ideas for humans; now it can directly handle tasks. For example, if you run a flower shop and want to build a website, you can give your AI a simple instruction: “Within a $100 budget, handle domain registration, hosting, images, and checkout pages.”

Then, this AI will negotiate, place orders, and make payments with multiple service providers, each transaction possibly just a few cents. Such activities are impossible with traditional bank cards due to high frequency, small amounts, and the need for repeated human authorization.

Mastercard’s Chief Product Officer explained quite plainly: “AP4M will truly enable the flourishing of AI-driven business models. The scale, speed, and amounts of machine payments are completely different from human payments today.”

So, what role does cryptocurrency play in this?

First, authorization records are stored on the blockchain. Permissions set for AI, such as maximum spending limits and types of services it can purchase, will be recorded on the Polygon blockchain.

Why put it on the chain? Because in the future, more than one system might verify whether AI has overstepped its authority. Storing this on a public ledger allows organizations to verify each other without relying on a centralized authority. Mastercard has chosen Polygon for its initial deployment.

Second, settlement supports stablecoins. Besides bank cards and accounts, this network also allows payments with stablecoins like USDC. Companies like Coinbase, Ripple, Solana, and others in the crypto space are involved.

RippleX’s Senior Vice President said, “Autonomous agents are already settling independently, but only when control is aligned. When control follows the payment, organizations can run with confidence. On-chain stablecoins enable instant settlement, programmable compliance, and full process auditing.”

The underlying logic of this system isn’t complicated: assign each agent a verifiable identity (credentialing); companies can set programmable rules (e.g., no single transaction exceeding $0.50); facilitate high-frequency transactions between agents; and finally, settle across channels.

Of course, Mastercard isn’t abandoning its traditional roots but is opening up its global clearing network while embedding crypto as a trust layer.

More than 30 companies have already expressed support, including Adyen, Ant International, Stripe, Cloudflare, Checkout.com, and others.

The significance of this is that traditional payment giants are not bypassing the crypto ecosystem but are instead using it as a tool to solve real-world problems. High-frequency, microtransactions, automation, cross-system operations—these scenarios are difficult for traditional channels but are well-suited for crypto.

However, some issues remain, such as how to prevent abuse of AI authorization boundaries? Who is responsible if an agent makes a mistake?

But these do not hinder the overall trend: future payments will shift from “requiring human confirmation to pay” to “programs automatically and continuously paying according to rules,” and Mastercard, as the world’s second-largest card organization, is leading the way.
