Banking, payments and staying safe from fraud
Written and reviewed by Prashant Nandkishor Maheshwari (editorial review, 2026-10-18). Not yet checked by an independent subject specialist. How we review.
What you will learn
Explain what banks do, compare account fees and features, and recognise common fraud patterns before acting on them.
Why it matters
Fees and fraud are two of the quietest ways to lose money. Both are easier to avoid once you know the patterns.
The ideas
Levels are a learning preference, not a credential. Switch any time.
Novice level
A bank takes deposits and lends money. It also lets you pay and be paid. Different accounts suit different needs: everyday spending, saving, or holding money for a fixed period.
Check the fees: monthly charges, minimum balance charges, transfer and card fees, and what happens if you overdraw.
Scammers use urgency, fear and trust. If someone contacts you and asks you to hurry, pause. A real organisation will let you check independently.
Basic level
Never share one-time passcodes (OTPs), PINs, passwords or card verification codes with anyone who contacts you, including people claiming to be from the bank.
Common patterns: a call about a 'blocked account', a link to 'update details', a request to pay a fee to receive a prize or loan, a 'refund' that asks you to send money first, an investment 'guaranteed' to pay a high return.
If in doubt, stop, and contact the organisation using a phone number or website you find yourself, not one you were given. Report suspected fraud quickly to your bank and local authority.
Advanced level
Compare the real cost of accounts and cards including foreign-exchange margins, which are often hidden in the rate rather than shown as a fee.
Expert level
Authorised push payment fraud shifts liability differently from card fraud in many regimes. Know the rules for each payment type you use.
Professional level
Strong customer authentication, KYC/AML duties and payment-system rules are set by regulators and scheme operators; follow those documents for compliance work.
Key terms
- Deposit
- Money you place with a bank.
- Overdraft
- Spending more than the account holds, usually with charges.
- OTP
- A one-time passcode that confirms a transaction. Never share it.
- Phishing
- A fake message designed to steal details.
Worked example
Illustration only. An account charges ₹150 a month unless the balance stays above 5,000. Over a year that is ₹1,800. Switching to a no-fee account for the same use removes a cost you had not noticed. Separately, a caller says your card is blocked and asks for the code just sent to your phone: that code lets them approve a payment, so you should end the call and phone your bank on its published number.
Try it yourself
Read your last three account statements. List every fee. For each, write whether it can be avoided or the account changed. Then write one rule you will follow for any urgent request for money or codes.
Nothing you write here is collected. Use paper or the workbook.

A common misunderstanding
'Only careless people get scammed.' Fraud works on pressure and trust. Anyone can be caught on a bad day.
Local context
Deposit protection, payment systems and reporting channels vary. For example, in some countries deposits are insured up to a set limit per depositor per bank; check your own country's limit and rules. In India, for instance, a UPI PIN is needed only to send money, never to receive it.
