Using Your Card Safely

Everything so far has been preparation. This chapter is the part you actually live with — and it starts with the single most expensive misunderstanding in Indian retail credit.

Your statement shows a total amount due and a much smaller minimum amount due. The minimum is the least you can pay to avoid a late fee and a missed-payment mark. That is all it is. It is not a repayment plan, it is not "what the bank expects", and paying it does not mean you have paid your bill.

Since the RBI's Master Direction on credit cards, issuers must set the minimum so that your balance cannot grow even if you pay only that, and unpaid charges and taxes cannot be capitalised into interest-on-interest. In practice most large issuers now compute it as the full interest plus GST plus fees plus any EMI instalment due, plus roughly 5% of the remaining principal.

That last number is why the trap is so effective, and why the two curves above diverge the way they do. Only about 5% of your principal comes off each month, while the whole balance keeps accruing interest at roughly 36% to 48% a year — and the interest-free period on new purchases is suspended the whole time, so every fresh swipe starts costing from the day you make it.

The fix: auto-debit set to the total amount due, with a buffer in the linked account a few days before the due date. If a balance has already built up, pay the maximum you can each month, and consider converting it to a fixed-tenure EMI at a much lower rate than revolving interest — run the tenure, rate and processing fee through our EMI calculator first, and read what "no cost" EMI really costs before accepting an offer at the till. Our guide to the minimum amount due trap runs the full worked example.

Credit utilisation is your reported balance divided by your total limit, and it is the fastest lever you have on your credit score. Sustained utilisation above roughly 30% is generally read as stress.

The detail that catches people out is that it is reported from the statement. The bureau does not see a monthly average and it does not see that you cleared the bill a fortnight later. It sees one photograph, taken on your statement date — which is the camera icon on the strip above.

That makes the timing of a part-payment matter more than the amount. Drag the marker before the statement date and the reported ratio drops; drag it after and the ratio stays high, even though you paid exactly the same money on exactly the same card.

Three ways to manage it:

• Part-pay before the statement date so a smaller balance is what gets reported.
• Ask for a limit increase. This lowers the ratio without you spending less, provided the larger limit does not change your behaviour.
• Spread spending across cards once you hold more than one, rather than running a single card near its ceiling.

The mechanics of how this feeds into your score are in chapter 3 and, in more depth, in our guide to how your CIBIL score works.

The practical advantage of credit over debit is that a fraudulent charge lands on a bill you have not paid yet, rather than on the balance you need for rent. But the cheapest protection is the one that stops the charge from being possible at all.

Almost every Indian issuer now lets you switch individual channels on and off in the app — international transactions, online, contactless and ATM — and set per-channel limits.

Flip each switch above and watch the matching path in the threat diagram go grey. That is not a metaphor: a channel that is off is a category of fraud that cannot happen to you.

If you never spend abroad, keep international transactions off until the day you travel. If you never withdraw cash, cap the ATM limit at zero — you already know from chapter 4 that you did not want to use it anyway. If you only ever tap in person, online can go off between purchases.

One afternoon of setup, and it holds for years.

The controls above are prevention. This module is what you do when something gets through, and the whole mechanism is speed.

Read every statement. Not the total — the line items. Small test transactions often precede large ones, and a ₹19 charge you do not recognise is a warning, not a rounding error.

Turn on transaction alerts for every channel, at the lowest threshold your issuer allows. That is what turns "spotted at the end of the month" into "spotted the same afternoon".

Report immediately. If a transaction is not yours, block the card in the app and raise the dispute with the issuer straight away — through the official app or the number printed on the card, never a number from a search result or a message. RBI's framework on limited liability for unauthorised electronic transactions turns substantially on how quickly you report, which is why the delay bar on the figure above is the only variable that matters.

Never share an OTP, CVV or PIN. No genuine bank employee will ask. The most common frauds in India are not technical attacks on cards; they are phone calls asking a person to read out a code, approve a UPI collect request, or install a screen-sharing app for "KYC verification".

A RuPay credit card can be linked to a UPI app, letting you pay at any UPI QR code from your credit line. It is genuinely useful — it extends card acceptance to millions of small merchants and, on cards that reward UPI spends, earns on payments that previously earned nothing.

Two cautions, and the first is arithmetic rather than risk. It feels exactly like paying from your bank account, and it is not: those payments join your statement and must be cleared in full like any other. Watch the drip above against the four large swipes beside it — many small, invisible UPI-credit payments reach a bigger statement total than a handful of purchases you actually remember.

Second, check what earns rewards. Issuers commonly exclude certain merchant categories from UPI-credit earning, so the reward rate you assumed may not apply to the spends you are putting through it.

The habit that fixes both is the "reconcile monthly" toggle: keep the app's spend summary in view, and check it against the statement once a cycle.

Three rhythms, and the whole of chapter 7 fits inside them.

Weekly, one minute: open the app, scan recent transactions, confirm you recognise all of them.

Monthly, five minutes: when the statement arrives, check the total, confirm the auto-debit is set to the full amount, look at the reported balance against your limit, and read the line items once.

Yearly, fifteen minutes: pull your credit report and check it for errors and unfamiliar accounts. Review whether each card still earns its keep — and if you are paying an annual fee for benefits you no longer use, think before closing the account, since closing an old card can shorten your average credit age and reduce your total limit.

Seven chapters, one habit doing most of the work: pay the total amount due, in full, on time, every month. Everything else — rewards, waivers, scores, limits — follows from it.
