History and Origins of M-Pesa

Early Origins

• M-Pesa was launched in Kenya in March 2007 by Safaricom, in partnership with Vodafone.
• The idea was to provide financial services to those underserved by traditional banking – especially the unbanked and underbanked.
• Initial pilot stages were funded also with support from the UK’s Department for International Development.

Growth and Expansion

• Over the years, M-Pesa expanded beyond Kenya to many African countries: Tanzania, Mozambique, Democratic Republic of Congo (DRC), Lesotho, Ghana, Egypt, Ethiopia, etc.
• It has grown in user-base, agent network, and functionality: from simple money transfers to payments, business services, app integration, mini-apps, etc.

Milestones

• By 2022, M-Pesa had more than 51 million customers, over 600,000 agents and 465,000 businesses using the platform.
• It processes tens of millions of transactions daily.

Core Services and Features

M-Pesa is more than just sending money. Its features include:

• Person-to-Person (P2P) transfers: sending money to another M-Pesa user.
• Cross-network transfers: sending to other mobile money wallets (e.g., Airtel Money or T-Kash in Kenya). With recent tariff changes many of these cross-network fees match M-Pesa-to-M-Pesa fees.
• Withdrawals: cash withdrawals via M-Pesa agents or ATMs.
• Bills & Goods Payment: via PayBill, Till, merchant services (Lipa na M-Pesa), etc.
• Saving & Credit Services: M-shwari, Fuliza, etc., depending on country-market. (Although more detailed data per country is needed.)
• Super App & Mini-Apps: As of recent years, M-Pesa has developed a Super App which lets users access a more unified interface and min-apps for partner services (e.g. transport, food, utilities) embedded inside.

How M-Pesa Works – Step by Step

Here is a simplified flow for a typical user in Kenya (other markets are similar with local adjustments):

Registration and Setup

1. Have a mobile phone & Safaricom line with valid SIM registration.
2. Register your M-Pesa account (often via USSD *334#, or via M-Pesa app / Super App). You’ll provide identity (ID, KYC) as required.
3. Choose a PIN to secure transactions.

Depositing / Funding Your M-Pesa Wallet

• Visit an M-Pesa agent (shops, retail outlets) and hand over cash to “deposit” into your mobile wallet.
• Alternatively, bank transfers or receiving from other M-Pesa users / cross-network wallets.

Making Transactions

• Send Money: through USSD, app, or SIM toolkit: choose “Send Money”, enter recipient number and amount, confirm with PIN.
• Pay Bills / Merchants: via PayBill or Till number, or via merchant’s interface in the Super App.
• Withdraw Cash: go to agent / ATM, request withdrawal, and confirm via PIN.

Other Features

• Check balance via USSD or app.
• Receive notifications or SMS confirmations.
• Mini-apps inside Super App for services beyond transfers (merchant shopping, insurance, etc.).

Fees, Charges and Limits (Kenya, 2025)

Here are the latest tariffs, limits, and fees for M-Pesa in Kenya as of 2025. These are official or consolidated from Safaricom’s rate announcements and reliable reporting.

Withdrawal (Agent and ATM)

• Agent Cash Withdrawal Charges: Ranging from KES 11 (for amounts like 50-100) up to KES 309 for large withdrawals above KES 50,000.
• ATM Withdrawal Fees: For some ranges, slightly different charges. Eg. withdrawing via ATM for certain amounts costs more.

Limits

• Maximum per transaction send: KES 250,000.
• Daily transaction limit / daily sending/wallet balance: KES 500,000.
• Minimum withdrawal: KES 50.

Other Tariffs

• PayBill / Till / Merchant charges vary; customer sometimes pays small fee, merchant may also incur fees depending on model.
• Business-to-Business (B2B) and Business-to-Customer (B2C) tariffs exist.

Regulatory, Trust and Security Considerations

To be credible, a system like M-Pesa must satisfy several areas of trust and compliance.

• KYC / Identification Requirements: Users must register with valid identity to access full range of services. This helps prevent fraud and money laundering.
• Regulation by Central Bank / Authorities: The service is regulated under mobile money/financial services law in Kenya and other countries. Changes like eliminating transfers to unregistered numbers were introduced for safety and fraud prevention.
• Agent Network Oversight: Agents are monitored. They are key touchpoints for depositing / withdrawing cash, so risks around liquidity, misuse, and fraud are managed via agent policies.
• Security Features: PIN verification, transaction confirmation via SMS or app, audit trails.
• Consumer Protection: Clear disclosure of fees, limits, and mechanisms for disputes or complaints.

Impacts on Financial Inclusion and Economy

M-Pesa is widely cited as a success story in using mobile technology to bring financial services to people who previously had limited access.

• Studies show M-Pesa helped lift many households out of poverty via enabling smoother remittances, saving, and risk management.
• It has significantly reduced costs and time for sending money, especially across rural-urban divides.
• It has encouraged innovation: new business models, mobile apps, merchant services, insurance etc.
• It has also increased the formal financial footprint of people, enabling them to build transaction histories and possibly access credit.

As of 2025, its fee structure has been updated to be more standardized, with free small-value transactions and clearer limits. For users, knowing the tariffs and managing transaction size (especially withdrawals) can help reduce costs.

For businesses, leveraging M-Pesa’s merchant, PayBill, or Mini-App offerings can open new customer access and payment routes.
