Core concepts
Electronic Funds Transfer (EFT) systems
EFT enables money to move between bank accounts without physical cash or cheques. The system operates through secure computer networks connecting banks, retailers and payment processors.
Key applications of EFT:
- BACS (Bankers' Automated Clearing Services) — used for direct debits, standing orders and salary payments in the UK, processing transactions in three working days
- CHAPS (Clearing House Automated Payment System) — processes same-day high-value transfers, often used for property purchases
- Standing orders — fixed amount payments set up by the account holder to pay regularly (e.g. monthly gym membership)
- Direct debits — variable payments where the recipient organisation can request different amounts each time (e.g. utility bills)
Advantages of EFT:
- Faster than processing paper cheques (no physical transportation required)
- More secure than carrying large amounts of cash
- Lower processing costs for banks and businesses
- Automatic payment reduces risk of forgetting bills
- Electronic records make tracking and auditing easier
Disadvantages of EFT:
- Requires internet/network connectivity to function
- Vulnerable to hacking and cyber-attacks
- Errors in amounts or account numbers can be difficult to reverse
- Elderly or vulnerable people may struggle with technology
- Bank system failures can prevent all transactions
EPOS (Electronic Point of Sale) systems
EPOS systems combine hardware and software to process sales transactions in retail environments. A typical system includes a barcode scanner, computer terminal, receipt printer, and connection to central databases.
How EPOS works:
- Barcode reader scans the product's unique barcode
- System searches the stock database for matching product code
- Product details (name, price, VAT rate) retrieved and displayed
- Item added to transaction total
- Payment processed through card reader or cash drawer
- Receipt printed with itemised list
- Stock database automatically updated (quantity decreased by 1)
- Sales data recorded for analysis
Benefits for businesses:
- Automatic stock control — system knows exactly what's been sold and current stock levels
- Faster checkout — scanning is quicker than manual price entry
- Fewer errors — eliminates mistakes from typing wrong prices
- Detailed reports — identifies best-selling products, peak trading times, staff performance
- Price changes — update centrally rather than relabelling every item
- Theft reduction — tracks all transactions against stock delivered
Drawbacks:
- High initial investment (hardware, software, installation, training)
- System failure stops all sales processing
- Barcode damage makes products unscannable
- Staff require training
- Regular maintenance needed
Automatic stock control systems
These computerised systems monitor inventory levels continuously, ensuring businesses maintain optimal stock without over-ordering or running out.
Key features:
- Reorder level — minimum quantity before new stock is ordered
- Reorder quantity — how many units to purchase when restocking
- Lead time — days/weeks between ordering and delivery
- Stock file — database containing product code, description, supplier details, current quantity, reorder level and reorder quantity
Process flow:
- EPOS system updates stock quantity after each sale
- Stock control system compares current quantity against reorder level
- When quantity falls below reorder level, system automatically generates purchase order
- Order sent electronically to supplier
- Supplier delivers stock with delivery note
- Goods received, barcode scanned, stock database updated
- System matches delivery against original order
Advantages:
- Never run out of popular items (maintains customer satisfaction)
- Reduces capital tied up in excess stock
- Minimises warehouse space requirements
- Less staff time spent manually checking shelves
- Identifies slow-moving products for discounting
Disadvantages:
- Cannot account for unexpected demand spikes (e.g. weather events, viral trends)
- System errors can lead to over-ordering or stockouts
- Requires accurate initial setup of reorder levels
- Theft or damage may not be reflected immediately in database
E-commerce and online shopping
E-commerce involves commercial transactions conducted electronically over the internet. The typical online shopping process demonstrates multiple ICT applications working together.
Online shopping process:
- Customer browses website using search and filter functions
- Products selected and added to virtual shopping basket/cart
- Customer account created or login to existing account
- Delivery address and contact details entered
- Payment processed (credit/debit card, PayPal, digital wallet)
- Order confirmation sent via email
- Warehouse system receives order, picks items, dispatches
- Tracking information emailed to customer
- Delivery confirmation and feedback request
Technologies supporting e-commerce:
- SSL (Secure Sockets Layer) certificates — encrypts data transmitted between customer browser and web server
- Payment gateways — secure services like WorldPay or Stripe that process card payments
- Shopping cart software — tracks selected items, calculates totals including delivery
- Customer databases — store account details, addresses, order history, preferences
- Recommendation engines — analyse browsing patterns to suggest products
Advantages for businesses:
- 24/7 trading without staff costs
- Global customer reach
- Lower overhead costs (no high street rent)
- Collect customer data for targeted marketing
- Easy price comparison and adjustment
Advantages for customers:
- Shop from home at any time
- Compare prices across multiple retailers instantly
- Access to wider product range
- Reviews and ratings help decision-making
- Price comparison websites find best deals
Disadvantages for businesses:
- High competition drives prices down
- Website development and maintenance costs
- Payment processing fees
- Returns handling more complex
- Cyber-security threats
Disadvantages for customers:
- Cannot physically examine products before purchase
- Delivery delays possible
- Returns more complicated than in-store
- Risk of online fraud or identity theft
- Needs internet access and basic ICT skills
Internet banking
Internet banking allows customers to access bank services through websites or mobile apps without visiting branches.
Typical features:
- View account balances and transaction history
- Transfer money between own accounts or to others
- Set up and manage standing orders/direct debits
- Pay bills to registered companies
- Apply for loans, credit cards or mortgages
- Download statements as PDF files
- Freeze lost/stolen cards immediately
Security measures:
- Usernames and memorable information — first authentication stage
- Passwords — second authentication factor
- Two-factor authentication (2FA) — requires code sent via SMS or app
- Encryption — HTTPS protocol scrambles data in transit
- Automatic timeout — logs out after period of inactivity
- Transaction limits — cap on daily transfer amounts
- Security questions — additional verification for sensitive actions
Benefits:
- Accessible 24/7 from anywhere with internet
- Instant transactions and balance updates
- No travel to branches required
- Reduced bank operating costs (fewer staff and branches needed)
- Immediate detection of unauthorised transactions
Risks:
- Phishing emails trick users into revealing login details
- Keylogging malware captures passwords
- Public Wi-Fi networks may be insecure
- Forgotten passwords lock accounts
- Elderly or disabled customers may struggle
Payment systems and security
Chip and PIN technology:
Payment cards contain an embedded microchip storing encrypted account information. At point of sale, the chip is read by the card terminal, and the customer enters their 4-digit PIN to authorise the transaction. The PIN is verified against encrypted data on the chip without transmitting it to the bank.
Advantages:
- More secure than signature (harder to forge PIN knowledge)
- Faster transaction processing
- Chip encryption prevents card cloning
- Liability for fraud shifts to customer if PIN compromised (incentivises security)
Disadvantages:
- Terminals more expensive than old swipe machines
- PIN can be observed by shoulder-surfing
- Forgotten PINs cause declined transactions
- Some disabilities make PIN entry difficult
Contactless payments:
Cards and smartphones with NFC (Near Field Communication) technology allow payments up to £100 by tapping on readers without entering PIN. Biometric authentication (fingerprint, face recognition) secures phone-based payments.
Online payment security:
- Card Verification Value (CVV) — 3-digit code on card back proves physical possession
- Address Verification System (AVS) — checks billing address matches card records
- 3D Secure — Verified by Visa/Mastercard SecureCode requires additional password
- PayPal/digital wallets — act as intermediary, hiding card details from merchants
- One-time codes — temporary card numbers for single transactions
Digital marketing
Businesses use ICT to promote products directly to targeted customers based on collected data.
Email marketing:
- Newsletters sent to subscribers
- Personalised offers based on purchase history
- Automated abandoned cart reminders
- Low cost per recipient
- Can track open rates and click-through rates
Social media marketing:
- Facebook/Instagram ads targeted by age, location, interests
- Influencer partnerships
- User-generated content and reviews
- Direct customer interaction
- Viral potential increases reach exponentially
Cookies and tracking: Websites store small text files (cookies) on users' devices to remember login details, track browsing behaviour and target advertising. Third-party cookies track users across multiple websites to build detailed profiles.
Advantages:
- Highly targeted reduces wasted advertising spend
- Measurable results (clicks, conversions, ROI)
- Can adjust campaigns in real-time based on performance
- Reaches customers where they spend time online
Disadvantages:
- Privacy concerns and legal regulations (GDPR)
- Ad-blocking software reduces effectiveness
- Customers perceive tracking as intrusive
- Easy for competitors to monitor campaigns
Worked examples
Example 1: EPOS system data flow
A supermarket uses an EPOS system. Describe what happens when a customer purchases a bottle of milk. [6 marks]
Answer:
- The checkout operator scans the barcode on the milk bottle using a barcode reader [1]
- The system searches the stock database for the matching product code [1]
- Product details including the description "Milk 2L" and price £1.20 are retrieved and displayed on the screen [1]
- The item is added to the customer's transaction total [1]
- When the customer pays, the transaction is recorded in the sales database [1]
- The stock database is automatically updated, reducing the milk quantity by 1 [1]
Examiner note: This question requires a logical sequence. Each step must be distinct and show understanding of system components working together.
Example 2: Internet banking security
Explain why banks use two-factor authentication for internet banking. [4 marks]
Answer: Two-factor authentication requires two different types of evidence to verify identity [1]. The first factor is something the customer knows (their password) [1], and the second factor is something they have (their phone to receive a one-time code via SMS) [1]. This makes unauthorised access much harder because even if a criminal obtains the password through phishing or keylogging, they cannot complete login without also possessing the customer's phone [1].
Examiner note: Marks awarded for defining 2FA, identifying both factors, and explaining why this combination increases security.
Example 3: Automatic stock control
A shop sells cricket bats. The reorder level is 15 bats and the reorder quantity is 50 bats. Currently 18 bats are in stock. On Monday, 5 bats are sold. Explain what happens in the automatic stock control system. [5 marks]
Answer: After 5 bats are sold on Monday, the EPOS system updates the stock database [1]. The new stock level is 13 bats (18 - 5 = 13) [1]. The stock control system compares this quantity (13) with the reorder level (15) [1]. Since 13 is below the reorder level of 15, the system automatically generates a purchase order [1]. The purchase order is for 50 bats (the reorder quantity) and is sent electronically to the supplier [1].
Examiner note: Calculation must be shown. Examiners look for understanding of the comparison process and automatic order generation.
Common mistakes and how to avoid them
Confusing EFT types — Students often mix up standing orders (fixed amount, payer controls) and direct debits (variable amount, recipient controls). Remember: direct debits allow the company you're paying to request different amounts each time, like a variable electricity bill.
Vague EPOS descriptions — Saying "it scans the barcode and processes the sale" lacks detail. Always specify that the system searches a database, retrieves specific data fields (description, price), updates stock quantity, and creates transaction records.
Overstating security — Claiming chip and PIN or internet banking is "completely secure" or "impossible to hack" loses marks. Always acknowledge that systems can be compromised through social engineering, shoulder-surfing, or sophisticated cyber-attacks, but the measures make it significantly more difficult.
Ignoring the human element — Disadvantages should include impacts on people: elderly customers struggling with technology, staff requiring training, businesses needing technical support. CIE IGCSE Information and Communication Technology examiners expect recognition that ICT affects different user groups differently.
Listing without explaining — Simply stating "faster, cheaper, more efficient" earns few marks. Each advantage must explain the mechanism: "EPOS systems are faster because scanning a barcode takes 2-3 seconds whereas manually typing product codes and prices could take 15-20 seconds per item."
Forgetting context — When asked about disadvantages of online shopping, mentioning "system crashes" is generic. Better: "If the e-commerce website crashes during checkout, customers cannot complete purchases, resulting in lost sales and frustration that may drive customers to competitor websites."
Exam technique for "ICT Applications: Business and Commerce"
"Describe" questions require logical sequences with specific detail. For processes like EPOS transactions or stock control, work through step-by-step, naming hardware components, software actions and data flow. Typically 1 mark per distinct point.
"Explain" questions need reasoning, not just statements. Use cause-and-effect structures: "Internet banking is available 24/7 because it operates through web servers that run continuously which means customers can access accounts at midnight or weekends therefore they don't need to wait for branch opening hours." Expect 2-3 marks per explained point.
Comparison questions demand parallel structure. If asked to compare online and high street shopping, create a table format in your mind: state one advantage of online (with reasoning), then contrast with the high street alternative. Avoid listing only one side.
Application to scenarios — Many questions present a business context (shop, bank, warehouse). Your answers must reference the specific scenario. If the question mentions "a school bookshop," discuss stock control for textbooks and uniform items, not generic retail goods.
Quick revision summary
Business and commerce rely heavily on ICT for transaction processing (EFT, chip and PIN), retail operations (EPOS systems connected to automatic stock control databases), and customer interaction (e-commerce websites with secure payment gateways). Internet banking provides 24/7 access through encrypted connections with two-factor authentication. Each system offers speed, accuracy and cost advantages but introduces cyber-security risks, requires initial investment, and may exclude less technologically confident users. Understanding specific processes, security measures, and real-world implications prepares you for CIE IGCSE Information and Communication Technology examination questions requiring description, explanation and evaluation of business ICT applications.
