Think of salary credits. Pension payments, dividend distribution, and EMI or SIP collections. NACH handles these interbank, periodic and bulk electronic transactions efficiently.

There are two sides to NACH. NACH Credit pushes money out, like salaries. NACH Debit pulls money in, like loan EMIs or utility mandates.

IMPS: Instant 24x7 Fund Transfers

IMPS (Immediate Payment Service) is a reliable electronic funds transfer system for instant payments between banks in India. You can use it via mobile, internet, ATM and SMS. It works every day of the year, including holidays.

IMPS is built on the existing NFS network. Is operated by NPCI. To participate. Banks must hold a valid RBI licence for banking or prepaid payment instruments.

The Payment and Settlement Systems Act. 2007 sets the procedural rules that apply to all IMPS members. Transfers are instant, available round the clock, and offer many access points.

Objectives of IMPS

• Enable secure, interoperable mobile payments between banks and mobile operators.
• Let customers use mobile devices as a payment channel.
• Simplify the overall payment process.

Registration for Remitter and Receiver

Each MMID is linked to one mobile number. However, a single mobile number can hold many MMIDs (one per account). IMPS transactions are settled between banks using settlement cycles.

Authentication in IMPS

Comparison Table: Major Digital Payment Systems in India

Use this quick-reference table for last-minute revision. It captures the most common exam angles in one place.

System	Full Form	Operated By	Best Used For	Availability
UPI	Unified Payments Interface	NPCI	Instant P2P & merchant payments	24x7x365
IMPS	Immediate Payment Service	NPCI	Instant interbank transfers	24x7x365
RTGS	Real Time Gross Settlement	RBI	Large-value, real-time transfers	24x7 (confirm latest)
NEFT	National Electronic Funds Transfer	RBI	Batch-based fund transfers	24x7 (half-hourly batches)
NACH	National Automated Clearing House	NPCI	Bulk & repetitive payments	Working days/cycles
AePS	Aadhaar Enabled Payment System	NPCI	Aadhaar/biometric banking	Via BC/micro-ATM

Note: Exact limits. Charges, cut-off times and availability windows change from time to time. Always confirm them on the latest official RBI / NPCI / IIBF notification.

RTGS vs NEFT vs IMPS: Know the Difference

This is a classic exam trap, so let us settle it clearly.

• RTGS settles each transaction individually and in real time. It is meant for large-value transfers.
• NEFT settles transactions in batches (half-hourly). It suits routine, smaller transfers and runs round the clock.
• IMPS gives instant, 24x7 interbank transfers and is operated by NPCI.

The simplest memory hook: RTGS = real-time + large value. NEFT = batch settlement; IMPS/UPI = instant retail. Always on.
