S S 2 Commerce Class Note: Modern Methods of Payment (Payment II)
In commercial transactions, payment is the lifeblood of trade. In our previous study of payment systems (Payment I), we examined traditional methods of payment, which primarily involved the physical exchange of cash, use of paper cheques, postal orders, and money orders. While these traditional methods served their purpose for decades, they posed significant challenges, including the risk of theft, slow transaction speed, high cost of printing cash, and geographical limitations.
With the rapid advancement of technology and the introduction of the Cashless Policy by the Central Bank of Nigeria (CBN), the landscape of commerce has shifted dramatically. Today, modern methods of payment rely heavily on electronic systems, telecommunications, and computer networks. These modern methods allow value to be transferred electronically, instantly, and securely across various distances without the physical exchange of paper money. This lesson explores the meaning, operations, advantages, and disadvantages of the primary modern methods of payment: Automated Teller Machines (ATM), Point of Sale (POS) terminals, Electronic Funds Transfer (EFT), and Mobile Banking.
Core Concepts
1. Automated Teller Machine (ATM)
An Automated Teller Machine (ATM) is an electronic telecommunications device that enables customers of financial institutions to perform financial transactions, such as cash withdrawals, deposits, funds transfers, account balance inquiries, and bill payments, at any time without the need for direct interaction with bank tellers or staff. ATMs are typically located outside bank branches, in shopping malls, petrol stations, airports, and other public spaces to provide round-the-clock banking services.
To access services via an ATM, a customer must possess a plastic smart card containing a magnetic stripe or an EMV chip (commonly referred to as a debit or credit card, such as Verve, Mastercard, or Visa) and a unique four-digit Personal Identification Number (PIN). The PIN acts as a secure digital signature to verify the identity of the cardholder.
How the ATM Works (Step-by-Step):
- Card Insertion: The user inserts their debit or credit card into the ATM card slot. The machine reads the account information stored on the card's chip or magnetic stripe.
- Language and PIN Entry: The machine prompts the user to select their preferred language and enter their unique four-digit PIN using the keypad.
- Transaction Selection: The ATM screen displays a menu of options (e.g., Withdrawal, Transfer, Inquiry, Bill Payment). The user selects the desired transaction.
- Processing: The ATM sends the transaction request securely through a telecommunications network to the customer's bank. The bank's computer system verifies the availability of funds and authorizes the transaction.
- Dispensation and Confirmation: If authorized, the ATM dispenses the cash or executes the transfer. It then prompts the user to retrieve their card, collects the cash, and prints a transaction receipt.
Advantages of ATM:
- 24/7 Availability: ATMs operate 24 hours a day, 7 days a week, allowing customers to access funds outside of official banking hours, including weekends and public holidays.
- Reduction of Bank Queues: By handling routine transactions like withdrawals and balance inquiries, ATMs significantly reduce the congestion and waiting times in banking halls.
- Convenience and Portability: Customers do not need to carry large sums of cash over long distances; they can travel light and withdraw money at any ATM location nearest to them.
- Multi-functional Operations: Modern ATMs do more than dispense cash; they allow users to buy mobile airtime, pay utility bills (like DSTV or electricity), and transfer money to other bank accounts.
Disadvantages of ATM:
- Risk of Fraud: ATMs are targets for cybercriminals who use card-skimming devices, pinhole cameras, or shoulder-surfing techniques to steal card details and PINs to withdraw money illegally.
- Technical and Network Failures: System downtime, network failures, or power outages can render ATMs temporarily unusable, or lead to "dispense errors" where a customer's account is debited without cash being dispensed.
- Security Threats: Users are sometimes vulnerable to physical attacks, robberies, or kidnappings at ATM points, especially in isolated or poorly lit areas at night.
- Transaction Fees: While withdrawals from a customer's own bank's ATM are usually free, using other banks' ATMs beyond a certain limit attracts maintenance or convenience fees.
2. Point of Sale (POS) Terminal
A Point of Sale (POS) terminal is a portable, handheld electronic device used by merchants and business owners to process card payments for goods and services sold at retail locations. Instead of paying with physical cash, a customer inserts or taps their debit card on the POS machine, and the exact cost of the purchase is electronically deducted from the customer's bank account and credited to the merchant's business bank account.
In Nigeria, the POS terminal has evolved beyond retail shops. It has driven the rise of "Agency Banking," where individuals act as human bank branches (POS Agents) in communities where physical banks are absent. These agents use POS terminals to offer cash withdrawal, deposit, and transfer services to the public for a small fee.
How the POS Works (Step-by-Step):
- Initiation: The merchant calculates the total cost of the customer's purchase and inputs this amount directly into the POS terminal.
- Card Reading: The customer inserts their debit card into the card reader (or taps it if it is a contactless card).
- Authentication: The customer is prompted to enter their secure four-digit PIN on the terminal's keypad to authorize the payment.
- Network Authorization: The POS terminal connects via a cellular network (GPRS/GSM) to the payment gateway (such as Interswitch or NIBSS) and the customer’s bank to verify funds.
- Completion: Once approved, the terminal debits the customer, credits the merchant, and prints two paper receipts—one for the customer and one for the merchant as proof of payment.
Advantages of POS:
- Enhanced Safety: It reduces the volume of physical cash handled by merchants, thereby minimizing the risk of cash theft, armed robbery, and employee pilferage.
- Sales Increase: Customers are not limited by the physical cash in their pockets. If they have money in their bank accounts, they can make unplanned or high-value purchases easily.
- Financial Inclusion: Through POS agents, banking services have been brought to rural, remote, and unbanked communities where physical bank buildings do not exist.
- Accurate Record Keeping: POS systems automatically record all sales transactions electronically, making bookkeeping and financial auditing easier for businesses.
Disadvantages of POS:
- Dependency on Cellular Networks: POS terminals require stable telecommunication networks to connect to banks. In areas with poor network coverage, transactions frequently fail or time out.
- Dispense Errors and Double Debits: Network hitches can lead to situations where a customer's bank account is debited, but the merchant's POS reads "Failed." Resolving these disputes can take several days.
- Operating Costs: Merchants pay transaction fees (MDR - Merchant Discount Rate) on every payment received via POS, which can reduce their profit margins.
- Battery Dependency: POS terminals run on rechargeable batteries. In environments with unstable electricity supply, keeping the devices charged can be challenging.
3. Electronic Funds Transfer (EFT)
Electronic Funds Transfer (EFT) is a broad term that refers to the transfer of money from one bank account to another through computer-based electronic systems, without the direct intervention of bank staff or the physical movement of paper money. EFT is the foundation of modern digital banking and is used for both retail (small value) and wholesale (large value) transactions.
In the Nigerian banking system, EFT is majorly driven by the Nigeria Inter-Bank Settlement System (NIBSS), which facilitates instant electronic transfers between different banks. The most common forms of EFT in Nigeria include NIBSS Instant Payment (NIP), National Electronic Funds Transfer (NEFT) which processes transactions in batches, and Real-Time Gross Settlement (RTGS) used for high-value corporate transfers.
How EFT Works (Step-by-Step):
- Initiation: The sender logs into their bank's portal (via internet banking or a mobile app) and inputs the recipient's bank name, account number, and the amount to be transferred.
- Verification: The system automatically retrieves and displays the recipient's registered name from the destination bank to ensure the sender does not transfer money to the wrong person.
- Authorization: The sender confirms the transaction by entering a security token code, transaction PIN, or biometric print.
- Clearing and Settlement: The sending bank routes the payment request through a central clearinghouse (like NIBSS). The clearinghouse debits the sending bank's settlement account and credits the receiving bank's account.
- Crediting: The receiving bank instantly credits the recipient’s bank account and sends a credit alert notification.
Advantages of EFT:
- Speed and Efficiency: Transfers are completed almost instantly (in the case of NIP), allowing businesses to settle payments and receive goods without delay.
- Convenience: Individuals and corporate bodies can transfer billions of Naira from the comfort of their homes or offices, eliminating the need to carry cash or write cheques.
- Paperless and Eco-friendly: It eliminates the cost and administrative bottlenecks associated with printing, writing, sorting, and clearing physical paper cheques.
- High Transaction Limits: EFT allows for the secure movement of very large sums of money that would be physically impossible or highly dangerous to move in cash.
Disadvantages of EFT:
- Cybersecurity Threats: EFT systems are primary targets for hackers, phishing scams, and malware attacks aimed at stealing banking credentials and diverting funds.
- Irreversibility of Errors: If a sender mistakenly transfers money to the wrong account number and authorizes it, recovering the money can be extremely difficult, especially if the recipient quickly withdraws the funds.
- System Interruption: Technical glitches at the clearinghouse level or within individual bank servers can halt national payment systems, disrupting commercial activities.
4. Mobile Banking
Mobile Banking is a service provided by banks and financial institutions that allows customers to conduct a wide range of financial transactions remotely using mobile devices, such as smartphones or basic feature phones. Mobile banking is divided into two primary platforms: Mobile Applications (Apps) and USSD (Unstructured Supplementary Service Data) Banking.
- Mobile Apps: These are specialized software applications downloaded onto smartphones (e.g., GTWorld, AccessMore, OPay, Moniepoint). They require an internet connection and offer a highly visual, secure, and interactive interface for transfers, statement generation, loan applications, and investment management.
- USSD Banking: This is a text-based technology that works by dialing shortcodes (e.g., *737#, *901#, *894#) on a mobile phone. USSD does not require an internet connection or a smartphone; it works on basic feature phones ("torchlight phones") and relies entirely on cellular network signals.
How Mobile Banking Works (Step-by-Step):
A. Mobile App Method:
- The user opens the app on their smartphone and logs in using a password, fingerprint, or facial recognition.
- The user selects the desired transaction (e.g., "Send Money").
- The user inputs the destination bank, account number, amount, and clicks transfer.
- The user enters their secret transaction PIN to authorize the payment.
- The transaction is processed instantly, and a receipt is generated on the screen.
B. USSD Method:
- The user dials their bank’s unique shortcode (e.g., *737#) on their mobile phone and presses call.
- A text menu appears on the screen with numbered options (1. Transfer, 2. Check Balance, 3. Buy Airtime, etc.).
- The user types the number corresponding to their choice and presses send.
- The user follows the subsequent prompts to enter the amount, account number, and their 4-digit USSD security PIN.
- The transaction is processed, and the user receives a confirmation SMS.
Advantages of Mobile Banking:
- Extreme Accessibility: It puts a complete bank branch inside the user's pocket, allowing transactions to be made anytime, anywhere, even in transit.
- Financial Inclusion for All: USSD banking has bridged the digital divide, allowing illiterate or rural populations without internet access or smartphones to participate fully in the formal economy.
- Cost-Effective: It saves customers the transport costs and time they would have spent traveling to a physical bank branch.
- Instant Notifications: Users receive real-time SMS or push notifications for every debit or credit transaction, allowing them to monitor their account activity instantly.
Disadvantages of Mobile Banking:
- Phone Theft Vulnerability: If a user’s mobile phone is stolen, criminals can bypass security or use SIM-swap fraud to access the victim's bank accounts via USSD codes.
- SIM-Swap Fraud: Criminals can fraudulently register a victim's phone number on a new SIM card, giving them access to the security codes (OTPs) sent by banks to authorize transactions.
- Network Failures: USSD sessions often time out or fail mid-way due to poor telecommunication network signals, leading to transaction uncertainty.
- Phishing and Social Engineering: Fraudsters regularly call or message users pretending to be bank customer care agents, tricking them into revealing their mobile app passwords or USSD PINs.

Contextual Examples
Example 1: The Automated Teller Machine (ATM)
Adebayo, a student at the University of Ibadan, needs to buy a recommended textbook from a local bookstore that only accepts cash. Since he does not have enough physical cash on him, he walks to a nearby bank ATM gallery. He inserts his Verve debit card, enters his PIN, selects "Withdrawal", chooses "Savings", inputs N5,000, and collects the cash along with his card. Adebayo successfully buys his textbook without needing to enter a bank banking hall or wait in a teller line.
Example 2: Point of Sale (POS) Terminal
Chioma visits a supermarket in Lagos to buy groceries worth N25,000. At the checkout counter, instead of counting out cash, she presents her Mastercard debit card to the cashier. The cashier inputs N25,000 into the POS terminal and inserts Chioma’s card. Chioma enters her secret PIN on the device. Within seconds, the machine prints out a receipt showing "Approved," and the N25,000 is transferred directly from Chioma's account to the supermarket's account.
Example 3: Electronic Funds Transfer (EFT)
Mr. Musa is a major distributor of cement in Enugu. He needs to pay his manufacturer in Dangote Cement, Obajana, the sum of N10,000,000 for a new shipment of cement. Carrying this amount of money in cash would be highly dangerous and physically exhausting. Instead, Mr. Musa sits in his office, logs into his bank's corporate internet banking platform, inputs the manufacturer's account details, authorizes the NIBSS Instant Payment (NIP) transfer with his hardware token, and the manufacturer receives the N10,000,000 instantly.
Example 4: Mobile Banking (USSD and App)
Mama Ngozi runs a small food stall in a local market in Onitsha. She does not own a smartphone or have access to the internet. When she wants to buy fresh vegetables from her supplier, she simply dials *901# (her bank's USSD code) on her basic feature phone, inputs her supplier’s account number, enters her security PIN, and sends N8,000. Both Mama Ngozi and her supplier receive SMS alerts within minutes, confirming the transaction without either party leaving the market.
Summary
Modern methods of payment have revolutionized the world of commerce by making transactions faster, safer, and highly convenient. The shift from physical cash and paper cheques to electronic systems has been driven by technology, telecommunications, and supportive government policies like the Central Bank of Nigeria's cashless policy.
The ATM has liberated bank customers from the constraints of banking hours, allowing cash access 24/7. The POS terminal has minimized cash handling risks for merchants and expanded banking access to rural areas through agency banking. Electronic Funds Transfer (EFT) has streamlined high-value business transactions, making instant payments across different banks possible. Finally, Mobile Banking (through Apps and USSD) has placed complete control of financial accounts directly into the hands of individuals, driving financial inclusion across all social classes.
While these modern methods offer immense benefits, they also present new challenges, particularly in the areas of cyber fraud, network instability, and system downtime. For commerce to thrive continuously, banks, businesses, and consumers must maintain a balance between embracing digital convenience and implementing robust security measures to protect financial assets.
