Amazon Pay is a digital payment service provided by Amazon that allows users to complete transactions on third-party websites, mobile applications, and select physical locations using the payment methods, addresses, and credentials stored in their Amazon account, offering a streamlined and secure checkout process without requiring additional account creation.[1] Originally launched in 2007 as Pay with Amazon and rebranded in 2017,Launched as part of Amazon's expansion into payment processing, Amazon Pay leverages the company's vast user base of over 310 million active customer accounts as of 2025 to facilitate faster conversions for merchants by reducing checkout friction and cart abandonment.[2] It supports one-click payments, automatic population of billing and shipping details, and integration with voice assistants like Alexa for hands-free purchases, while providing customers with order tracking through Amazon's "Your Orders" section. Security is enhanced by Amazon's A-to-z Guarantee, which protects eligible purchases against issues like non-delivery or misrepresentation, and advanced fraud detection tools that minimize chargebacks for merchants.[2][3]Available in the United States, United Kingdom, 15 European countries, Japan, India, Canada, and Australia as of 2025 (with recent expansions of Amazon Pay Later features), Amazon Pay supports 12 currencies and various payment types such as credit cards, debit cards, and in some markets, buy-now-pay-later options through partners like Affirm.[3] For merchants, integration is straightforward via e-commerce platforms like Shopify, WooCommerce, and BigCommerce, or directly through Amazon's APIs, with transaction fees typically at 2.9% plus $0.30 per successful charge in the U.S., plus an additional 1% for international transactions.[4] This service has evolved to include features like QR code payments in Japan since 2018 and adaptive checkout options, positioning it as a competitive alternative to services like PayPal in the digital wallet space.[3]
History
Origins and Launch
Amazon Pay originated as Amazon's initiative to extend its payment capabilities beyond its own marketplace, beginning with the launch of Amazon Flexible Payments Service (FPS) on August 2, 2007, in a limited beta phase.[5] This service enabled developers to integrate secure payment processing into their applications using Amazon account credentials, marking the company's entry into digital payments for third-party sites.[6]The initial purpose of FPS, which laid the groundwork for what would become known as Pay with Amazon and later Amazon Pay, was to leverage Amazon's vast customer base by offering one-click, secure payment options outside the core e-commerce platform.[7] By allowing users to pay on external websites without entering new payment details, it aimed to simplify transactions and build trust through Amazon's established authentication systems.[6]Technically, the service was built on Amazon's existing e-commerce infrastructure, incorporating basic digital wallet functionality to handle fund transfers between buyers and sellers via web services APIs.[5] This foundation emphasized scalability and reliability, drawing from the payment processing that powered Amazon's internal operations. At launch, FPS was primarily available in the United States, with expansion to select countries like the United Kingdom following in subsequent years.[6]Over time, this early payment system evolved into modern offerings such as Amazon Pay UPI, adapting to diverse regional needs while retaining the core principle of seamless integration.[8]
Key Milestones and Acquisitions
In 2013, Amazon re-launched its payment service as Pay with Amazon, a consumer-facing one-click payment option for third-party merchants, building on the FPS foundation.[9] In 2017, the service was rebranded as Amazon Pay to unify Amazon's login and payment features and expand its global presence.[8]In 2013, Amazon acquired GoPago, a San Francisco-based mobile payment startup specializing in tablet-based point-of-sale systems, to bolster its capabilities in mobile and in-store transactions.[10][11] The acquisition allowed Amazon to integrate GoPago's technology for faster checkout experiences, marking an early expansion beyond online-only payments.[12]By 2019, Amazon Pay formed a strategic partnership with Worldpay, the first payments acquirer to fully enable Amazon Pay for its merchants, facilitating broader e-commerce processing in the US and Europe.[13][14] This integration streamlined one-click payments for Worldpay's clients, enhancing Amazon Pay's reach in international markets.[15]In 2020, Amazon launched "Pay with Alexa," enabling voice-activated payments through Echo devices for scenarios like fueling at Exxon and Mobil stations.[16][17] Powered by Amazon Pay and Fiserv, the feature expanded hands-free commerce, starting with over 11,500 US locations.[18]In 2024, Amazon explored launching a dedicated standalone app for Amazon Pay in India to promote greater independence from the main Amazon shopping app and drive higher adoption in the competitive digital payments landscape.[19][20] This consideration aimed to capitalize on India's growing UPI ecosystem by improving accessibility and user engagement.[21]In October 2025, Amazon Pay introduced UPI Circle as an upgrade to its UPI service in India, allowing primary account holders to securely share payment access with family members and integrate transactions on smartwatches and wearables.[22][23] Announced at the Global Fintech Fest, the feature supports one-time approvals for trusted contacts, simplifying group payments while maintaining security.[24][25]
Discontinued Services
Checkout by Amazon (CBA) was an early one-click payment service launched by Amazon in July 2008, allowing merchants to integrate Amazon's checkout process into their websites for seamless transactions using Amazon account credentials.[26] This service enabled customers to purchase from third-party sites without entering payment details anew, leveraging Amazon's trusted infrastructure. However, Amazon discontinued CBA effective April 1, 2017, as part of a broader effort to unify its payment offerings.[27]Parallel to CBA, Amazon introduced the Flexible Payments Service (FPS) in August 2007 as a developer-focused web service API for handling money transfers, including micropayments and recurring billing, integrated with Amazon Web Services.[5] FPS was designed to give developers flexible control over payment flows but saw limited uptake compared to competitors like PayPal. Support for FPS ended on June 1, 2015, with Amazon phasing it out to redirect resources toward more advanced payment solutions.[28]The discontinuations of CBA and FPS were driven by Amazon's strategy to simplify its payment ecosystem, enhance security through updated protocols, and consolidate under the Amazon Pay brand for better scalability and user experience.[29] These legacy services were replaced by a unified platform that offered improved API compatibility and fraud protection, reducing fragmentation for merchants and developers. During the transition period, Amazon provided migration guides and API updates to facilitate the shift, ensuring minimal disruption as users and partners adopted Amazon Pay for ongoing transactions.[27]
Products and Services
Core Amazon Pay
Amazon Pay serves as the foundational digital wallet service within Amazon's payment ecosystem, enabling seamless online transactions for consumers on third-party merchant websites. Users authenticate via their existing Amazon account credentials, which grants access to a one-click checkout option without requiring repeated entry of personal or financial details on the partner site. This process leverages Amazon's secure infrastructure to store and manage payment information in a centralized digital wallet, facilitating quick and convenient purchases while maintaining user privacy.[30][31]The service supports a range of standard payment methods, including major credit and debit cards from networks like Visa, Mastercard, American Express, Discover, Diners Club, and JCB, as well as direct bank account debits and Amazon gift card balances. By handling all sensitive data through Amazon's encrypted systems, customers avoid sharing full payment details with merchants, reducing friction and enhancing security during transactions.[32][33][34]For merchants, integrating Amazon Pay via provided APIs offers significant advantages, such as decreased cart abandonment due to the familiarity and trust associated with Amazon's brand. This integration is straightforward for e-commerce platforms like Shopify or WooCommerce, allowing businesses to tap into Amazon's vast customer base without building their own payment processing systems, thereby improving conversion rates and operational efficiency.[2][3]As of 2024, the core Amazon Pay service operates in 18 countries, including the United States, United Kingdom, India, and various European nations such as Germany, France, and Italy, providing essential digital wallet capabilities for cross-border and local online payments.[3]
Amazon Pay Express
Amazon Pay Express is a streamlined integration option within Amazon Pay, designed to enable faster and simpler checkout experiences on third-party websites and apps. Introduced to simplify merchant setup, it allows developers to incorporate a single Amazon Pay button using minimal code, often through a button generator that provides copy-and-paste HTML for instant access to users' stored payment and shipping details.[35] This approach reduces development time and technical complexity, making it accessible for merchants seeking quick deployment without extensive API customization.[36]In contrast to the core Amazon Pay, which involves more comprehensive API interactions and full user authentication flows, Amazon Pay Express features a lighter API footprint that initiates the process with a simple button click, deferring full Amazon login until necessary for confirmation. This design prioritizes speed and minimal friction, particularly for high-traffic e-commerce environments, by leveraging a widget-based interface that pre-fills details and supports biometric verification where available.[37] Built on the core Amazon Pay wallet, it enables returning customers to complete transactions using saved information without re-entering data.[38]The solution is particularly suited for small e-commerce sites, where it facilitates one-click payments directly on product or checkout pages, avoiding full redirects to Amazon's domain and thereby lowering cart abandonment rates. Common use cases include guest checkouts and impulse buys, with support for major credit cards and select local payment methods to enhance conversion.[37][38]Since the mid-2010s, Amazon Pay Express has seen widespread adoption among merchants in the United States and Europe, driven by its ease of implementation and access to Amazon's global user base exceeding 300 million active accounts. It is available in regions including the US, UK, Belgium, and Luxembourg, contributing to higher authorization rates through tokenized payments.[37][38]
Amazon Pay UPI and Variants
Amazon Pay UPI was launched on February 14, 2019, initially for Android users in India, enabling customers to link their bank accounts directly through the Amazon mobile app for instant, secure transfers via the Unified Payments Interface (UPI). This integration with India's UPI system, developed by the National Payments Corporation of India (NPCI), allowed users to generate a virtual payment address (VPA) in partnership with Axis Bank, facilitating peer-to-peer (P2P) and merchant payments without traditional banking apps.[39][40]By July 2024, Amazon Pay UPI had processed approximately 72.4 million transactions, capturing about 0.5% of the total UPI volume in India, amid a competitive landscape dominated by apps like PhonePe and Google Pay. The service's adoption grew significantly, reaching over 100 million customers by August 2024, driven in part by cashback incentives and rewards programs that offered up to 5% returns on eligible transactions, encouraging frequent use for everyday payments.[41][42]In October 2025, Amazon Pay introduced UPI Circle, a feature unveiled at the Global Fintech Fest in Mumbai on October 8, enhancing family-oriented payment sharing within the UPI ecosystem. Primary account holders can add up to five family members—such as spouses, children, or elderly relatives—without requiring separate bank accounts, assigning preset spending limits and providing each member with a personalized UPI ID or QR code for independent transactions. Security is bolstered by biometric authentication for PIN-less approvals, either via one-time delegation or per-transaction verification, allowing real-time expense tracking and control by the primary user.[22]UPI Circle also integrates with smart devices, including Amazon Echo speakers and wearables like smartwatches, enabling voice-activated or tap-and-go payments through device-level encryption and NPCI-compliant fraud detection. This expansion targets underserved groups, such as teens aged 13-17 without bank accounts and household managers aged 30-50, while offering cashback rewards on family transactions to promote broader digital payment adoption.[22][43]Beyond core transfers, Amazon Pay UPI supports various use cases tailored to Indian users, including utility bill payments (e.g., electricity, water, and broadband), mobile and DTH recharges, and merchant interactions via QR code scanning through the app's "Scan & Pay" feature. Users can initiate these by linking a bank account or RuPay credit card in the Amazon app (version 26.3.0.300 or later), entering a UPI PIN at checkout, and completing transactions instantly across online platforms, physical stores, or third-party merchants.[44][45]
Features and Functionality
Security and Fraud Protection
Amazon Pay implements robust security measures to protect user payment data, including end-to-end encryption during transmission and tokenization to replace sensitive card details with non-exploitable tokens, ensuring that actual payment information is not stored on merchant servers.[46][3] These protocols, such as Transport Layer Security (TLS), safeguard data from interception while in transit, aligning with industry standards for payment processing security.[3]To combat fraud, Amazon Pay employs artificial intelligence (AI) and machine learning (ML) algorithms through services like Amazon Fraud Detector for real-time transaction monitoring and anomaly detection.[47] These systems analyze patterns in user behavior and transaction data to flag potential fraudulent activities, such as unauthorized purchases or account takeovers, before they complete.[48] As of 2025, Amazon Pay continues to leverage predictive ML models in its fraud detection to minimize chargebacks.[47]A notable historical security incident occurred in 2010 with Amazon Simple Pay, a precursor to modern Amazon Pay services, where researchers identified a logic flaw in the payment flow that allowed attackers to manipulate transactions and obtain goods without payment.[49] Discovered by Rui Wang and colleagues, the vulnerability stemmed from insufficient protection against cross-origin interference in cashier-as-a-service integrations, enabling unauthorized access to payment sessions.[50]Amazon promptly addressed the issue by November 1, 2010, through updated software development kits (SDKs) and enhanced validation mechanisms to prevent such exploits.[51]In 2025, Amazon Pay expanded its security features with the UPI Circle integration, incorporating biometric authentication such as fingerprint and face ID for PIN-less transactions, particularly in family-shared payment setups and wearable devices.[22] This addition uses device-level encryption and real-time verification tied to Aadhaar data in India, reducing reliance on traditional PINs while maintaining compliance with paymentsecurity standards.[52] Partnerships, such as with Worldpay, further support these efforts by enabling secure integrations that adhere to PCI DSS compliance for global transactions.[13]
Integrations and User Enhancements
Amazon Pay enhances user experience through seamless integrations with voice assistants, developer APIs, and additional perks, while providing merchants with robust tools for optimization. One key integration is voice-activated payments via Alexa, introduced in 2020, which enables hands-free purchases on Echo devices for supported transactions such as fuel at ExxonMobil stations.[53] This feature requires a four-digit voice code for confirmation to ensure security during voice commands.[54]For developers, Amazon Pay offers comprehensive APIs that facilitate custom integrations into websites, mobile apps, and other platforms, allowing for tailored payment flows.[55] A significant update came with API Version 2, released on January 7, 2021, which introduced improved endpoints for checkout sessions, charges, and refunds to streamline development and enhance compatibility.[56] Release notes and migration guides support ongoing updates, enabling developers to maintain secure and efficient integrations.[57]User enhancements include perks like cashback and rewards programs, which incentivize adoption, alongside one-click setup for faster transactions using existing Amazon account details.[58] In 2025, Amazon Pay expanded these features through UPI Circle, a family payment solution launched on October 8, allowing primary account holders to share UPI access with up to five family members for PIN-less transactions via biometric authentication, with spending limits and expense tracking.[22] This initiative also extends UPI payments to smart devices like wearables in partnership with NPCI, supporting tap-and-go functionality with device-level encryption and real-time notifications, and offering up to 5% cashback on qualifying transactions.[22]Merchants benefit from dedicated tools such as transaction reports and analytics dashboards that provide insights into payment behaviors, conversion rates, and customer trends to inform business decisions.[59][60] Additionally, integration testing protocols allow for A/B experimentation with payment button placements and configurations during development and production to optimize user engagement and checkout performance.[61] These tools collectively reduce friction in the payment process while enabling data-driven refinements.
Operations and Impact
Global Reach and Partnerships
Amazon Pay has achieved significant international expansion since its initial launch in 2007 as a limited betaservice, evolving into a widely available payment solution across multiple regions. As of 2024, it operates in 18 countries, including the United States, United Kingdom, Germany, India, Japan, and various European nations such as Austria, Belgium, France, Italy, and Spain.[3] The service adapts to local regulatory frameworks, notably ensuring compliance with the European Union's General Data Protection Regulation (GDPR) for data privacy in European markets.[62]Key partnerships have facilitated this global footprint, with notable collaborations enhancing payment processing and integration capabilities. In 2019, Amazon Pay integrated with Worldpay to streamline transactions for merchants outside the Amazon ecosystem, enabling broader e-commerce adoption.[14] Additionally, seamless integrations with platforms like Shopify and WooCommerce allow merchants to incorporate Amazon Pay as a checkout option, leveraging Amazon's trusted user base for faster conversions.[63][64]Regionally, Amazon Pay emphasizes tailored offerings to meet market demands. In India, it has a strong presence through Unified Payments Interface (UPI) integrations, supporting the country's digital payment ecosystem. In Europe, the focus lies on Amazon Pay Express, which prioritizes quick e-commerce checkouts while adhering to stringent data protection standards. The expansion strategy has been gradual, building on core markets post-2007 before accelerating into emerging regions.[65]Recent pushes in the Middle East and North Africa (MENA) region highlight ongoing growth, with Amazon Payment Services— the local arm of Amazon Pay—operating in nine countries including the United Arab Emirates, Saudi Arabia, Egypt, Jordan, Lebanon, and Qatar. In 2024, a multi-year partnership with Mastercard aimed to digitize payment acceptance across MENA and Africa, capitalizing on rising digital wallet trends. By 2025, collaborations such as with Tamara for buy-now-pay-later options further supported flexible payment adaptations in high-growth markets like the UAE and Saudi Arabia.[66][67][68]
Market Adoption and Statistics
Amazon Pay has demonstrated steady growth in transaction volumes, processing approximately $75 billion worldwide in 2024 and an estimated $85 billion in 2025.[69] In India, where Amazon Pay operates prominently through UPI integrations, adoption of digital payments including UPI jumped 35% in fiscal year 2025, with transaction volumes reflecting this surge amid broader preferences for online modes among urban consumers.[70] Projections for 2025 indicate continued expansion, bolstered by AI-driven fraud prevention measures that enhance security and user trust, potentially accelerating adoption in high-growth markets.[71]In terms of market share, Amazon Pay captured approximately 0.6% of India's UPI transactions as of early 2025, ranking it among the top players despite dominance by larger providers like PhonePe and Google Pay.[72] In the United States, it holds a 5.3% share of the digital wallet market as of 2025, positioning it as the third-largest option behind PayPal and Apple Pay, particularly for third-party e-commerce payments.[69] These figures underscore Amazon Pay's niche but significant role in fragmented payment ecosystems, with overall UPI market growth in India forecasted at a compound annual rate exceeding 270% through 2029.[73]The service has delivered measurable economic benefits to merchants, including reduced cart abandonment through streamlined, one-click checkouts that leverage user familiarity with Amazon's ecosystem, contributing to higher conversion rates compared to standard merchant processes.[74] In 2025, Amazon introduced policy updates for sellers, such as credits covering return fees for FBA remote fulfillment starting March 25, which streamline operations and improve payout efficiency by minimizing unexpected costs.[75] These enhancements support faster cash flow for third-party sellers, aligning with bi-weekly settlement cycles that process sales minus expenses.[76]Looking ahead, 2025 trends highlight Amazon Pay's emphasis on the MENA region, where digital payments are surging—digital wallets like those integrated with Amazon Payment Services are the fastest-growing method in the UAE and Saudi Arabia, amid a broader shift away from cash.[71] In India, the standalone Amazon Pay app is poised to drive further growth by capitalizing on rising offline digital payment adoption, which reached 56% for in-store purchases in 2025, up from 48% the prior year.[70]
