Modern Banking Services and Digital Payments
This domain tests retail electronic payment systems, their limits and settlement timings, and the security rules around them. Expect comparison questions on NEFT, RTGS, IMPS, UPI and cards.
Core systems
- NEFT: 24x7 retail funds transfer; no minimum; batch-based settlement historically, now round-the-clock.
- RTGS: real-time gross settlement; minimum ₹2 lakh; no upper limit; 24x7.
- IMPS: immediate, 24x7, mobile-based; typically up to ₹5 lakh per transaction.
- UPI: NPCI-operated instant payment system using a virtual payment address; generally up to ₹1 lakh per transaction, with higher caps for specified categories.
- AePS: Aadhaar-enabled payment system for micro-ATMs and business correspondents.
- Cards: EMV chip, tokenisation, additional factor authentication; contactless limits are set by RBI.
- Prepaid payment instruments: full-KYC, minimum-KYC and gift categories, each with balance limits.
- Security: RBI's unauthorised electronic transaction rules give zero liability if the customer reports within three working days, with graded liability thereafter.
Worked example
A customer wants to pay ₹3 lakh by UPI in one transaction. The standard UPI cap is ₹1 lakh, so the payment will fail unless the category has a higher cap. The customer can use RTGS, since ₹3 lakh exceeds the ₹2 lakh RTGS minimum, or split the payment. The reasoning is to match the amount to the system's limit and settlement feature, not to assume all digital transfers are interchangeable.
Traps
- RTGS has a minimum, not a maximum.
- UPI is not NEFT; it is a separate instant system.
- A payment bank can issue a debit card but not a credit card.
- Zero liability is not automatic; prompt reporting is required.
- Contactless and UPI limits are regulatory, not bank discretion.
