How agents, digital wallets, and trust are rewriting checkout

The internet economy is reshaping checkout around mobile purchasing, digital wallets, local payment preferences, and AI-assisted shopping. Stripe’s analysis of nearly 20,000 B2C businesses shows that customers increasingly complete expensive purchases on mobile, expect region-specific payment options, and are becoming more open to buying through AI agents. Businesses that adapt checkout to local behavior and manage fraud intelligently can improve conversion while reducing unnecessary declines. ## Mobile Checkout Is Expanding to Higher-Value Purchases - Mobile dominates purchases under $50, but shoppers are increasingly using phones for purchases over $500. - This trend is strongest in APAC and EMEA, where mobile is already the preferred checkout device. - In the US, mobile gained share across every purchase range measured over the past two years. - Canada is an exception, with shoppers more likely to switch to desktop for purchases between $100 and $249. ## Digital Wallets Depend on Region and Generation - Digital wallets represent roughly 30% of global point-of-sale volume. - Sixty-one percent of surveyed shoppers said they would use a digital wallet. - Younger shoppers are especially likely to use wallets, including for purchases over $250. - Wallets cut average mobile checkout time in half, making speed a major advantage. - Preferences vary by market, from MB WAY in Portugal and MobilePay in Denmark to Alipay in China. - Businesses need to support the wallet mix that is actually popular in each region rather than relying only on Apple Pay, Google Pay, and similar global options. ## Localization Requires the Right Payment Mix - Forty-five percent of surveyed consumers made at least one international online purchase in the previous year. - International demand does not guarantee conversion; checkout must match local expectations for currency, payment methods, and presentation. - Markets such as Indonesia and Vietnam have fragmented preferences across wallets, bank transfers, debit-linked apps, and other local methods. - In more concentrated markets, conversion may depend heavily on supporting one dominant payment method. - Showing an irrelevant payment option can reduce conversion by up to 15%. - Supporting local leaders can significantly improve results: - BLIK increased Polish checkout conversion by an average of 46%. - Pix increased Brazilian checkout conversion by an average of 31%. ## AI Agents Are Changing Checkout and Payment Risk - Consumers are increasingly open to AI agents helping with purchase decisions. - Shopping and product discovery are moving into tools such as Google Gemini, Microsoft Copilot, visual search systems, and retailer-specific assistants. - Automated fraud, including card testing, is becoming easier to scale. - Overly strict risk controls can reject legitimate customers along with fraudulent transactions. - New payment models use more real-time signals, selective authentication, and improved routing and retries to balance fraud prevention with conversion. - Stripe reports that its AI-driven interventions can reduce fraud by 30% without lowering conversion. ## Checkout Becomes a Verification Layer Checkout is evolving beyond a final payment screen into a system that verifies identity, purchase intent, and authorization. Businesses should prioritize mobile performance, offer payment methods that reflect each market’s behavior, and prepare for transactions initiated by AI agents. The strongest checkout experiences will be fast, locally relevant, and capable of distinguishing legitimate buyers from automated fraud.

Introducing the Machine Payments Protocol

AI agents are moving beyond chatbots toward autonomous systems that plan, act, and evaluate results, creating demand for agent-friendly commerce. Stripe and Tempo are launching the Machine Payments Protocol (MPP), an open standard that lets agents make programmatic payments to businesses and services. MPP supports microtransactions, recurring payments, stablecoins, fiat, and existing Stripe payment methods without requiring human intervention. ## The Challenge of Agent Payments - Traditional financial workflows are designed for humans. - Agents often cannot independently: - Create accounts - Navigate pricing and subscription options - Enter payment details - Configure billing - These obstacles limit agents’ ability to purchase services and participate in the internet economy. ## How the Machine Payments Protocol Works - An agent requests a resource from a service, API, MCP server, or other HTTP endpoint. - The service returns a payment request. - The agent authorizes payment. - The requested resource is delivered automatically. - Stripe businesses can integrate MPP through the PaymentIntents API with only a few lines of code. - Payments appear in Stripe’s existing API and Dashboard and settle through the business’s normal balance, currency, and payout schedule. - Standard Stripe capabilities remain available, including tax calculation, fraud protection, reporting, accounting integrations, and refunds. ## New Agentic Business Models MPP is already enabling agents to pay for services such as: - Browserbase: headless browsers billed per session - PostalForm: printing and mailing physical documents - Prospect Butcher Co.: ordering food for pickup or delivery in New York City - Stripe Climate: making programmatic contributions - Parallel Web Systems: paying per API call for web access Payments can use stablecoins, cards, buy now, pay later methods, and Shared Payment Tokens. ## Stripe’s Agent Economy Infrastructure Stripe positions MPP alongside its broader Agentic Commerce Suite, Agentic Commerce Protocol, MCP integrations, and support for x402. Together, these tools are intended to help businesses sell directly to agents and support new automated commerce patterns. Businesses interested in enabling agent payments can review Stripe’s MPP documentation and join the early-access program.
