That change lowered distribution costs, sped up communication, and let companies connect payments, banking, lending, investing, and insurance to the websites and apps people already use. But connectivity was an enabling foundation—not a complete explanation. Smartphones, cloud computing, digital identity, payment systems, data, regulation, and consumer trust determined how far fintech could grow and who could benefit.
What fintech means—and what it does not
Fintech is the use of technology to provide, improve, automate, or distribute financial services. It includes consumer-facing products such as digital wallets and online lending, as well as the underlying systems that help banks, merchants, insurers, and payment providers move money or assess risk.
The term is broader than cryptocurrency. Crypto and blockchain are parts of the fintech landscape, not synonyms for it. It is also useful to distinguish fintech companies from digital financial services: a bank offering an app is digitizing its service, while a technology-oriented company may build a new payment, credit, or investment model. In practice, the line is not always sharp. Many fintech brands rely on regulated banks or other licensed institutions to hold deposits, extend credit, or provide financial products.
How the internet changed financial services
The internet transformed both the delivery system and the business models of finance. Its main contributions reinforce one another:
#1 Best Overall
- Wider reach: Customers can access accounts and financial products remotely, including in places where branches are scarce or travel is costly.
- Lower distribution costs: Digital onboarding, applications, statements, and servicing can reduce dependence on paper, cash handling, and physical locations. This can lower providers’ costs, although users may still pay data, account, cash-out, foreign-exchange, or credit fees.
- Greater speed and availability: Connected services allow customers to check balances, pay bills, apply for credit, or transfer money outside branch hours. They also allow providers, merchants, and payment processors to exchange information more quickly.
- Data for decisions: Digital transactions can create records used for fraud detection, identity checks, credit assessment, and personalization. Alternative data may help assess people with little conventional credit history, but it can also be incomplete, intrusive, biased, or difficult to challenge.
- Platforms that connect markets: Online systems can bring borrowers and lenders, merchants and payment providers, or investors and businesses together. A financial product can also be offered inside a non-financial app rather than through a bank’s own website.
Connectivity alone does not create a working financial service. Firms and public institutions also need reliable networks, secure software, usable payment infrastructure, rules for handling data and money, and a way to identify customers.
The technology stack behind fintech’s expansion
Mobile phones and apps
Mobile networks and smartphones turned internet-based finance into an everyday activity. Apps can combine account access with biometric authentication, notifications, QR-code payments, digital cards, customer support, and budgeting tools. In markets with limited fixed broadband or branch coverage, mobile access has been particularly important.
Cloud computing and APIs
Cloud computing provides storage and computing capacity that can scale with demand, without every provider having to build and maintain its own large data infrastructure. Application programming interfaces, or APIs, let different systems exchange information or initiate actions, such as connecting a bank account to accounting software or enabling a payment through an online marketplace. These connections can make services more convenient, but they also raise questions about security, consent, and dependence on technology vendors.
Digital identity, automation, and AI
Remote identity checks and electronic know-your-customer processes can reduce the need for paper forms and branch visits. But people without formal identification, reliable devices, or consistent personal records may still be shut out, while weak identity controls can expose users to theft.
Recommended Free Tools
Artificial intelligence and machine learning now support fraud detection, customer-service chatbots, credit scoring, anti-money-laundering monitoring, and automated investment tools. They are an increasingly important layer, not the original reason fintech expanded: connectivity, mobile access, payments infrastructure, and digital records laid much of the groundwork first.
Payment rails and distributed ledgers
Internet-connected apps need systems that move funds between people, firms, and financial institutions. Card networks, mobile-money systems, bank transfers, and fast-payment infrastructure provide those rails. Blockchain and other distributed-ledger technologies support some approaches to settlement, tokenization, and programmable transactions, but they are only one branch of fintech—not its universal foundation.
Rank #2
Payments became fintech’s mass-market entry point
Payments made the shift visible to many consumers first. Online card payments, mobile money, digital wallets, peer-to-peer transfers, QR codes, contactless payments, payment gateways, merchant services, and digital remittances all depend on connected systems. Once people use a wallet or payment account, a provider may be able to offer additional services, such as savings, credit, insurance, or business tools.
In emerging market and developing economies, the share of adults using digital payments rose from 35% in 2014 to 57% in 2021, according to BIS Working Paper No. 1196, published July 8, 2024. The figure captures broad adoption growth; it does not mean that every user had the same level of access or used digital payments frequently.
Fast-payment systems can amplify that growth by making transfers immediate and supporting new finance apps. A BIS study finds that retail fast-payment systems can encourage app adoption, competition, and services beyond payments, including borrowing, investing, and insurance. It identifies stronger effects where systems have open membership, real-time settlement, and active central-bank involvement. The internet supplies the communication environment; interoperable payment rails help determine whether services can scale across providers.
How fintech moved beyond payments
Digital banking and neobanks
Online banking moved familiar tasks—checking balances, paying bills, and transferring funds—onto websites and phones. Neobanks build a digitally native customer experience, often without a conventional branch network, and may offer automated budgeting, instant alerts, or digital cards. The brand a customer sees is not always the bank that holds the funds: some neobanks operate through a partner institution. Customers should check which legal entity provides the account, holds deposits, and handles complaints.
Digital lending
Online applications and automated underwriting can speed up loan decisions. Internet-based lenders include marketplace and peer-to-peer platforms, buy-now-pay-later providers, lenders embedded at e-commerce checkout, and services that use transaction data to assess applicants. These models may reach some borrowers who have thin credit files, but quick access is not automatically beneficial. Unclear pricing, repeated refinancing, unaffordable repayment terms, aggressive marketing, data misuse, and automated decisions that are hard to contest can cause harm.
An IMF working paper, “Promise (Un)kept? Fintech and Financial Inclusion,” reports that the relationship between fintech and inclusion varies by instrument and country. In its sample, digital lending had a negative and statistically significant relationship with financial inclusion; the overall fintech effect was positive and statistically significant in developing countries but statistically insignificant in the full sample. Those findings describe that study’s analysis, not a universal result for every market or borrower.

Investing, wealth management, and crowdfunding
Online brokerages, robo-advisers, fractional shares, automated portfolio tools, and digital retirement services can lower practical barriers to investing. But easier access does not guarantee suitable choices: users may misunderstand risk, trade excessively, or buy products they do not understand.
Crowdfunding platforms connect people or organizations seeking funds with dispersed contributors or investors. The category includes donation and reward crowdfunding, peer-to-peer lending, equity offerings, and real-estate funding. The financial and legal risks differ across these models, so “crowdfunding” alone does not indicate whether a contribution is a donation, a loan, or an investment.
Insurance, remittances, and embedded finance
Insurtech uses connected systems for online quotes, digital claims, usage-based policies, automated underwriting, and insurance offered alongside another purchase. Data-driven pricing may tailor coverage, but it can also increase privacy and discrimination concerns.
Digital remittance services can reduce reliance on physical transfer locations and improve convenience. Cross-border transfers still face identity and compliance checks, currency conversion, fees, correspondent-banking arrangements, and uneven interoperability.
Embedded finance places payments, credit, insurance, or other services inside platforms such as e-commerce sites, ride-hailing apps, payroll tools, accounting software, and travel marketplaces. Customers may use a financial service without visiting a bank’s website—or recognizing the provider as a conventional financial institution. That makes it important to know which company is responsible for the product and customer support.
Why fintech adoption—and inclusion—vary
Countries have followed different paths. Some extended branch-based banking with online services; others expanded through smartphones, mobile money, or agent networks that let customers deposit and withdraw cash locally. Mobile money has been especially significant where conventional branches are sparse, but no single model works everywhere.
Rank #4
The World Bank’s Global Findex 2025 is based on nationally representative surveys of approximately 148,000 adults in 141 economies conducted during 2024. It includes comparable indicators on mobile-phone ownership, internet use, digital safety, payments, saving, borrowing, and financial risk management. These measures help show why account ownership alone cannot tell the full story.
Internet coverage is only one condition for access. A person may also need an affordable smartphone and data plan, reliable service, a usable interface, formal identification, digital skills, trust in providers, and merchants that accept digital payments. Barriers can differ for rural residents, lower-income households, women, older adults, people with disabilities, migrants, refugees, and microbusinesses.
Access is not the same as meaningful use. An account may exist but be used only to receive a payment, withdraw cash, or make an occasional transfer. More meaningful inclusion involves services that are affordable, reliable, safe, useful, and suited to people’s needs—including the ability to save, borrow responsibly, manage shocks, and resolve problems.
Digital channels can complement physical access rather than eliminate its value. Branches, agents, and in-person support may remain important in cash-intensive economies, for complex products, for people who need accessibility help, and when customers need to resolve disputes.
What the evidence says about scale and economic effects
Global account ownership increased from 51% of adults in 2011 to 76% in 2021, according to figures cited by the IMF’s 2024 working paper. That trend coincided with expansion in digital finance, but account ownership is not proof that internet access alone caused the increase or that every account improved its holder’s welfare.
The IMF Financial Access Survey release in October 2024, covering data through 2023, described the expansion of mobile and internet banking alongside declines in some regions’ traditional access points, including branches and ATMs. Its 2025 annual report covers 163 economies and tracks digital financial products. Such changes show that delivery channels are shifting, not that physical services have become unnecessary everywhere.

Transaction growth is evidence of scale, but by itself it does not measure affordability, consumer outcomes, or financial resilience.
BIS Working Paper No. 1196 also reports an association between digital-payment adoption and subsequent growth and productivity in a panel of 101 economies. This is observational macroeconomic evidence, not definitive proof that digital payments independently caused those outcomes. Lower transaction friction and broader access may support economic activity, but results also depend on infrastructure, institutions, competition, and how people and businesses use the services.

The pandemic pushed consumers, merchants, governments, and financial institutions toward remote transactions. Online commerce, contactless payments, remote account access, digital government payments, and remote identity checks became more important when in-person activity was restricted. The World Bank describes COVID-19 as accelerating the digitization of financial services and money. It did not create the underlying shift: internet connectivity, smartphones, payment systems, and software infrastructure were already making remote finance possible.
Risks that grow with digital finance
- Fraud and cybersecurity: Connected accounts can be exposed to scams, account takeovers, identity theft, and cyberattacks. Fast transfers can make fraudulent payments difficult to reverse.
- Privacy and data control: Digital products may collect transaction and behavioral information. Users may not understand what is collected, how long it is kept, or how it affects decisions about price or eligibility.
- Bias and weak recourse: Automated decisions may reproduce errors or discrimination in data. Customers need explanations, ways to correct inaccurate information, and routes to appeal decisions.
- Over-borrowing and mis-selling: Convenient, always-available credit or investment access can encourage impulse decisions. Poorly understood terms, repeated borrowing, or unsuitable products can turn convenience into financial harm.
- Operational concentration: Firms may depend on a small number of cloud providers, platforms, or payment networks. A disruption at a critical provider can affect many services at once.
- Market power: Large platforms can use extensive data, established user bases, merchant relationships, and cross-selling to compete effectively. Those advantages can also create dependence or weaken competition over time.
- Digital exclusion: People without devices, affordable connectivity, identification, accessible design, or confidence using digital services can be left behind as essential services move online.
These risks explain why a digital account is not automatically safer or cheaper than a traditional one. The relevant question is whether the product’s total costs, protections, and reliability work for the customer.
Why regulation and public infrastructure matter
Fintech services may be supplied by banks, payment institutions, e-money issuers, lenders, broker-dealers, technology vendors, or brands working through partner institutions. The regulatory rules and customer protections can differ by provider and country. A central challenge is making sure responsibility is clear when multiple firms combine to deliver a single app-based service.
BIS FSI Insights No. 33 identifies the regulatory perimeter for non-bank payment providers and e-money as a key policy issue, drawing in part on a survey of 75 jurisdictions conducted in early 2021. Regulators also need to address consumer protection, cybersecurity, data handling, digital credit, competition, and oversight of bank-fintech partnerships. The World Bank’s guidance on inclusive digital financial services likewise emphasizes regulatory frameworks, agent networks, consumer protection, cybersecurity, data protection, and interoperability.
Public infrastructure matters alongside private products. Identification systems, telecom networks, fast-payment rails, open standards, and rules for access to payment systems can influence whether competing providers can reach customers and whether users can transact across platforms. If a wallet cannot connect to other networks or reach useful merchants, its value is limited.
What to check before using a fintech service
- Identify the legal provider of the account, loan, investment, or policy—not just the app’s brand.
- Check what protections apply to your money in your country, and which institution is responsible for holding it.
- Read the full fee and pricing terms, including cash-out charges, foreign-exchange costs, late fees, and recurring subscriptions.
- Understand what personal and transaction data the provider collects, shares, and uses in eligibility or pricing decisions.
- For credit, check the total repayment amount, due dates, consequences of missed payments, and whether refinancing is encouraged.
- For investments and insurance, establish what is and is not covered, what risks you carry, and how to contact the provider if something goes wrong.
- Use strong account security, enable available alerts, and know how to report an unauthorized transaction promptly.
The internet made it commercially practical to distribute finance at scale and helped move services from branches into apps, platforms, and everyday transactions. Whether that reach produces broad benefit depends on more than a connection: usable infrastructure, fair rules, reliable providers, consumer protection, and genuine access for people who might otherwise be excluded all matter.
