Question 10

Explain the process of an e-commerce transaction from order to delivery.

Accepted Answer

An e-commerce transaction follows a systematic process from selecting a product to delivering it to the customer.

First, the customer visits an e-commerce website or app, searches for the product, compares features/prices and selects the required item. The customer then adds the product to the cart.

Next, during checkout, the customer enters delivery address, chooses delivery option and confirms the order details. After that, the customer selects a payment method such as UPI, debit/credit card, net banking, wallet or cash on delivery. Once payment is successful, the system generates an order confirmation and invoice/receipt.

After confirmation, the seller or warehouse processes the order. The product is picked, packed and handed over to the delivery partner. The shipment is tracked through order tracking updates until the product is delivered to the customer.

Finally, if there is any issue like wrong item, damage or size problem, the customer can request return or replacement as per the policy. In case of return, the refund is processed to the original payment method or wallet.

Thus, e-commerce transaction involves product selection, order placement, online payment, order processing, delivery and after-sales support like returns and refunds.

Question 11

Explain digital payment modes (UPI, cards, net banking, wallets) with brief examples.

Accepted Answer

Digital payments are electronic payments made without using physical cash. Common digital payment modes are as follows:

1) UPI: UPI allows instant bank-to-bank transfer using UPI ID or QR code. Payment is authorized using UPI PIN. Example: paying a shopkeeper by scanning QR code.

2) Debit/Credit cards: Customers pay using card details and authentication such as PIN or OTP (for online payments). Debit card uses money from bank account, while credit card allows payment on credit limit. Example: card swipe/tap at a POS machine.

3) Net banking: Payment is made through bank’s website/app using login credentials. It includes transfers like NEFT/RTGS/IMPS and online bill payments. Example: transferring money to a supplier through bank portal.

4) Wallets: Wallets store money in an app balance and can be used for quick payments and recharges. Some wallets can also link bank accounts/cards. Example: paying small amounts quickly using wallet balance.

Therefore, UPI, cards, net banking and wallets are widely used digital payment modes that support e-commerce and cashless economy.

Question 12

Explain security measures in e-commerce and digital payments.

Accepted Answer

Security is very important in e-commerce and digital payments because online frauds like phishing, fake links, OTP theft and unauthorized transactions are common. To protect customers and businesses, several security measures are used.

Firstly, secure communication through HTTPS and encryption helps protect data during transmission. Websites and apps use encryption so that payment and login details are not easily intercepted.

Secondly, authentication mechanisms like 2FA are used. For card payments, OTP or 3D secure authentication is required. For UPI payments, the user must enter UPI PIN to authorize transactions. This ensures that even if someone knows basic details, they cannot complete payment without the second factor.

Thirdly, alerts and monitoring are important. Banks and apps send SMS/email notifications for transactions. Fraud detection systems monitor unusual activity and can block suspicious transactions.

Fourthly, user-side safety practices also matter. Users should never share OTP, UPI PIN or CVV; they should verify payee name and amount; avoid public Wi‑Fi for banking; keep apps updated; and use screen lock/app lock.

Finally, dispute and reporting systems help reduce loss. If an unauthorized transaction occurs, quick reporting to the bank/app and cyber authorities can help block further transactions and start investigation.

Thus, encryption, 2FA, monitoring, alerts and responsible user behavior together provide security in e-commerce and digital payments.

Question 13

Define digital payment.

Accepted Answer

Digital payment is an electronic payment made without physical cash using modes like UPI, cards, net banking or wallets.

Question 14

Differentiate between debit card and credit card (any three points).

Accepted Answer

1) Debit card uses money directly from the bank account, whereas credit card uses a credit limit provided by the bank.
2) Debit card amount is deducted immediately, whereas credit card payment is billed and paid later as per billing cycle.
3) Debit card generally has lower risk of overspending, whereas credit card can lead to interest/charges if payment is delayed.

(Any three differences can be written.)

Question 15
