Electronic Payment System (e-Payment) is a type of payment conducted via electronic or online mediums. Online payment systems eliminate the need for cash or cheque payments. It is a unique payment method that allows you to conduct online transactions via digital wallets, bank cards and internet banking systems. The funds are directly debited from your bank account.

Types of Electronic Payment Systems (EPS)

Electronic Payment Systems (EPS) facilitate cashless transactions through digital and electronic means. These systems can be classified into two major categories: online payment systems (internet-based) and offline payment systems (non-internet-based).

1. Online Electronic Payment Systems (Internet-Based)

These payment methods require an active internet connection and are commonly used for e-commerce, online shopping, bill payments, and fund transfers.

A. Card-Based Payments

Card-based payments are among the most widely used digital payment methods, where transactions are processed using credit, debit, or prepaid cards.

• Credit Cards: These allow users to borrow money from banks for purchases, which they must repay later. Credit cards often come with benefits like reward points, EMI options, and cashback offers. For example, a customer purchasing a smartphone from Flipkart using an HDFC Credit Card can opt for an EMI payment plan.

• Debit Cards: Unlike credit cards, debit cards directly deduct money from the user’s bank account, ensuring that users only spend what they have. For instance, someone paying an electricity bill through an SBI Debit Card will have the amount instantly deducted from their bank balance.

• Prepaid Cards: These cards are loaded with a fixed amount of money and can be used for payments until the balance is exhausted. An example of this is an Amazon Pay Gift Card, which allows customers to shop online within the available balance.

B. Bank-Based Payments

Bank-based electronic payments involve direct transactions between bank accounts via online platforms or applications.

• Net Banking (Internet Banking): This method enables users to log into their bank’s website and transfer funds, pay bills, and manage transactions. For instance, a person can pay their LIC insurance premium through ICICI Net Banking without visiting a branch.

• UPI (Unified Payments Interface): UPI allows instant fund transfers between bank accounts using mobile applications like Google Pay, PhonePe, and Paytm. For example, a person can send ₹1,000 via Google Pay by simply entering the recipient’s UPI ID or scanning a QR code.

• Electronic Funds Transfer (EFT): EFT refers to direct transfers between bank accounts, including NEFT (National Electronic Funds Transfer), RTGS (Real-Time Gross Settlement), and IMPS (Immediate Payment Service). A common use case is salary payments, where companies credit employee salaries via NEFT transactions.

C. Wallet & Mobile Payments

With the rise of smartphones, digital wallets and mobile payment apps have become popular for quick and easy transactions.

• Mobile Wallets (E-Wallets): These are apps that store digital money, allowing users to pay instantly for goods and services. For example, customers can pay for food on Zomato using Paytm Wallet, eliminating the need for entering bank details each time.

• Buy Now, Pay Later (BNPL): This option lets customers purchase products now and pay later in instalments, often with zero interest. An example is Amazon Pay Later, which allows users to buy a laptop and pay in EMIs over a few months.

D. Cryptocurrency Payments

Blockchain technology has introduced decentralised digital currencies for secure transactions.

• Blockchain-Based Payments: Cryptocurrencies like Bitcoin, Ethereum, and Ripple allow payments without traditional banking systems. For example, some companies accept Bitcoin payments for software services, making transactions global and decentralised

2. Offline Electronic Payment Systems (Non-Internet-Based)

These payment methods do not require an internet connection and include physical card transactions, contactless payments, and bank transfers.

A. Card-Based Payments (Without Internet)

Even without an internet connection, debit, credit, and prepaid cards can be used for payments through physical machines and terminals.

• Point of Sale (POS) Transactions: POS terminals allow businesses to accept card payments by swiping, inserting, or tapping a card. For example, a person can pay for groceries at Big Bazaar using a debit card on a POS machine.

• Near Field Communication (NFC) & Contactless Payments: NFC technology enables users to tap their smartphones, smartwatches, or contactless cards on a POS machine to make payments. Apple Pay and Samsung Pay allow users to tap and pay without inserting their cards.

• QR Code Payments: QR codes are widely used for digital transactions, where customers scan a QR code and authorize payment from their bank account or digital wallet. A street vendor may accept payments through a PhonePe QR code without needing a POS machine.

B. Bank-Based Offline Transfers

Banks also offer non-internet-based electronic payment options for fund transfers and bill payments.

• Direct Debit: This method enables automated deductions from a user’s bank account for recurring payments like subscriptions, utility bills, or loan EMIs. For example, Netflix subscription payments are deducted automatically from the linked bank account every month.

• Electronic Checks (E-Checks): E-Checks are the digital version of paper checks, processed electronically by banks. For instance, a tenant may use an E-Check to pay rent to their landlord instead of writing a paper check.

• Wire Transfers: Wire transfers allow direct bank-to-bank transactions without needing an internet connection. These are commonly used for international money transfers via services like Western Union or SWIFT.

3. Emerging Payment Systems

With advancements in technology, AI, and cybersecurity, new digital payment methods are emerging to enhance security and user experience.

• Biometric Payments: Payments using biometric authentication, such as fingerprint scans, facial recognition, and retina scans, are becoming increasingly popular. Apple Pay and Google Pay now support Face ID authentication for transactions, ensuring secure and fraud-proof payments.

• Voice-Activated Payments: AI assistants like Alexa, Google Assistant, and Siri allow users to make payments using voice commands. For instance, a user can say, “Alexa, pay my electricity bill,” and the payment will be processed using the linked account.

• Central Bank Digital Currency (CBDC): Governments worldwide are exploring digital versions of their national currencies. India, for example, has introduced the Digital Rupee (e₹) by RBI, which functions like physical cash but in digital form, offering secure and instant transactions.

E-Money

E-Money (Electronic Money) refers to digitally stored monetary value that is used for making payments without involving physical cash. It is typically stored in electronic devices, prepaid cards, bank accounts, or digital wallets and allows users to conduct transactions quickly and securely over the internet or offline.

Preventive Measures: Regular security audits, firewalls, and intrusion detection systems can help prevent hacking attempts.

2. Phishing Attacks

Phishing is a social engineering attack where fraudsters trick users into revealing sensitive information like passwords, credit card numbers, or personal details. This is done through fake emails, websites, or messages that appear to be from legitimate sources.

Example: A customer receives a fraudulent email pretending to be from Amazon, asking them to verify their payment details on a fake website.

Preventive Measures: Businesses should educate users about phishing awareness and implement email authentication protocols.

3. Identity Theft & Account Hijacking

Cybercriminals steal users’ personal information to impersonate them and make fraudulent purchases. This is often done through password breaches or data leaks.

Example: A hacker gains access to a user’s e-commerce account by stealing their login credentials and uses stored payment details for unauthorized transactions.

Preventive Measures: Use multi-factor authentication (MFA), strong passwords, and biometric verification for secure login processes

4. Payment Fraud

Payment fraud occurs when stolen or fake credit cards, unauthorized chargebacks, or fraudulent transactions are used on an e-commerce platform.

Example: A fraudster uses a stolen credit card to purchase expensive items and later issues a chargeback, causing the merchant to lose money.

Preventive Measures: Implement AI-powered fraud detection systems, tokenization, and transaction monitoring.

5. Distributed Denial of Service (DDoS) Attacks

DDoS attacks overload e-commerce websites with fake traffic, causing server crashes and website downtime. This prevents real customers from accessing the platform, leading to financial losses.

Example: A DDoS attack on an online store during holiday sales makes the website unavailable, preventing real transactions.

Preventive Measures: Use DDoS protection services, cloud-based security solutions, and load balancing techniques.

6. Malware and Ransomware Attacks

Malware (malicious software) is used to steal data, spy on users, or encrypt files and demand ransom (ransomware) for data recovery.

Example: A ransomware attack locks an e-commerce store’s database, demanding a ransom for access to customer orders and payment records.

Preventive Measures: Install antivirus software, update security patches, and backup data regularly.

7. SQL Injection (SQLi) Attacks

SQL injection attacks target a website’s database by inserting malicious SQL commands to access or manipulate data.

Example: A hacker uses an SQL injection attack to extract customer payment details from an online store’s database.

Preventive Measures: Implement input validation, use parameterized queries, and restrict database access.

8. Man-in-the-Middle (MitM) Attacks

In MitM attacks, hackers intercept communications between a customer’s device and an e-commerce website to steal payment data.

Example: A cybercriminal intercepts Wi-Fi traffic and captures credit card details during an online purchase.

Preventive Measures: Use SSL/TLS encryption, secure Wi-Fi networks, and VPNs for data protection.

9. Data Breaches and Information Leaks

A data breach occurs when sensitive customer or business data is exposed due to weak security measures.

Example: A cyberattack on a retail platform leaks millions of customer email addresses, passwords, and credit card details.

Preventive Measures: Use strong encryption, access controls, and secure cloud storage.

10. Insider Threats

Employees or business partners may intentionally or accidentally leak sensitive information or introduce security vulnerabilities.

Example: A disgruntled employee sells customer data to cybercriminals.

Preventive Measures: Implement strict access controls, regular employee training, and monitor internal activities.

Basics of encryption and decryption 

Encryption and decryption are essential techniques used in cybersecurity to protect sensitive information. These processes ensure that data remains secure, confidential, and accessible only to authorised users. They are widely used in e-commerce, online banking, secure communications, and data storage.

1. What is Encryption?

Encryption is the process of converting plain text (readable data) into ciphertext (unreadable format) using an encryption algorithm and a key. The purpose of encryption is to prevent unauthorised access to sensitive information.

Example: When a customer enters credit card details on an e-commerce website, encryption ensures that the information is securely transmitted and cannot be intercepted by hackers.

Real-World Use: Online transactions, email security, password storage, and secure messaging apps like WhatsApp use encryption.

2. What is Decryption?

Decryption is the reverse process of encryption. It converts ciphertext back into plain text using a decryption algorithm and a key. This allows authorised users to access the original data.

Example: When an online banking system receives an encrypted login request, it decrypts the data to verify the user’s identity.

Real-World Use: Reading secured emails, decrypting credit card transactions, and accessing protected files.
