Digital Retail, E-commerce and Payment Awareness
This domain tests awareness of how digital channels and digital payments work in retail, and how to handle them without creating a loss.
E-commerce models
B2B, B2C, C2C, D2C (brand sells directly), marketplace (operator connects sellers and buyers) versus inventory-led (operator owns stock), quick commerce and social commerce. Omnichannel links the store and the website - for example BOPIS, buy online pick up in store. ONDC is an open network that lets small sellers be discovered across apps.
Digital payments
Cards (EMV chip with PIN, contactless tap), UPI (VPA, QR scan, collect request, UPI PIN), wallets, net banking, NEFT/IMPS/RTGS for account transfers, BNPL and cash on delivery. A payment gateway authorises the transaction; settlement credits the merchant account later, after deducting the merchant discount rate.
Safety rules that examiners test
Never share OTP or UPI PIN, even with someone claiming to be from the bank. Check the merchant name and the amount on a collect request before approving it. Verify payment success on the merchant device. Watch for tampered QR codes and phishing links. For a failed transaction where money was debited, the auto-reversal process applies; the customer should raise it with the bank or the app, not pay again immediately.
Worked example
A customer's UPI app shows 'pending' while the POS shows 'failed'. Reasoning: money may be in transit, so do not hand over the goods and do not ask the customer to pay a second time, which risks a double debit. Note the transaction reference, ask the customer to wait for the status to settle, verify on the merchant app, and if the amount is debited without a matching credit, guide the customer to raise a reversal request.
Compliance
E-commerce operators collect tax at source on taxable supplies and report it in their returns; the rate and thresholds are revised from time to time, so verify the current rule rather than memorising an old figure.
Traps that cost marks
Accepting a payment screenshot as proof; sharing an OTP 'to help' a customer; and re-initiating payment on a pending transaction.
