IMPS or Immediate Payment Service was the seed that was sown thirteen years ago and digital payments like UPI as we know them today are a direct result of IMPS. Secure transactions, smooth bank interoperability, and lightning fast speed are just a few of IMPS’s myriad of perks.

Let’s take a deep-dive into the intricacies and functionalities of IMPS

IMPS can be used for sending money to friends and family (person-to-person), transferring funds to a bank account (person-to-account), and making payments to merchants (person-to-merchant). IMPS is run by the National Payments Corporation of India (NPCI) and you can access it using mobile banking apps, internet banking, short message service (SMS), and automated teller machines (ATM).

Now that you already know what is meaning of IMPS, let’s dive into its features and more.

Features of IMPS

To understand why IMPS is a popular choice for money transfers, here are its key features:

1. Instant Transfers

IMPS stands out for its instant transfers, crediting the recipient’s account immediately. This is in contrast to NEFT or RTGS, which can take some time to complete.

2. 365*24*7 Service

IMPS is a 24/7 service, available year-round including holidays, allowing individuals to make transactions anytime.

3. User-Friendly

IMPS is user-friendly and can be accessed through any smart device with an internet connection, making it easy to use on the go.

4. Cost Effective 

IMPS transactions typically have lower fees compared to other transfer methods.

5. Safe and Secure

IMPS employs secure methods like OTPs (One Time Passwords) to safeguard your transactions.

6. No Need for Bank Details

With IMPS, customers don’t need to share bank details like bank account numbers to make transactions, making it a convenient and hassle-free option.

How does IMPS Work?

Now that you have a brief idea of what is IMPS transfer, let’s understand how it works. IMPS is a payment rail for real-time interbank electronic transfers in India.

From a technical perspective, the process consists of the following aspects: 

1. The Infrastructure

The National Payments Corporation of India is the central hub and the backbone that looks after the IMPS transactions conducted in the country. They keep a very smooth infrastructure to ensure the smooth functioning of the IMPS transactions, which includes:

1.1 IMPS Switch

It is a highly secured and robust channel by which all the banks establish a valid connection. This channel helps to quickly transfer funds from one place to another and simultaneously transfer transaction-related data. 

1.2 Message Broker

It is a routing system incorporated into the IMPS system. It routes information among various participants in the ecosystem.

1.3 Directory Services

It comprehensively records all the participating banks and their technical configuration. It is one of the most explicitly designed centralised databases for all the participants.

2. The Communication Protocol

The Financial Industry Business Messaging Scheme (FIBOS) is the standardised messaging format that ensures banks communicate reliably and securely with the NPCI. FIBOS messages contain information about the sender, data about the beneficiary and the transaction amount, and authentication data.

By adhering to the FIBOS standard, banks guarantee smooth and risk-free exposure, eventually leading to rigorous trust and cooperation across the banking segment. Moreover, this standardised protocol ensures the increased integrity of communication and reliability of transaction processes.

3. The Transfer Process

3.1 Initiation

The sender initiates the transfer via their bank’s mobile app/portal or ATM. Then, the bank’s system will confirm the credentials by verifying their MPIN/OTP and creating an IMPS message enclosing the transaction details in the FIBOS format. 

3.2 Message Transmission

The IMPS Switch then securely sends the transfer information to the NPCI, ensuring a secure and efficient transfer process. 

3.3 Routing and Validation

NPCI uses directory services to track and route the message to the bank where the beneficiary has the account. At the same time, NPCI validates the bank account, the format of the message and the current balance of the account to meet the transaction needs securely and accurately. 

3.4 Authorisation

In the case of successful routing and validation by NPCI, the authorisation message is sent to the bank, allowing its functioning to transfer the funds.

3.5 Funds Debit

The specified amount is debited from the sender’s account, and the bank updates its internal records. Thus maintaining an updated record of actual transactions and managing the rest of the balance. 

3.6 Clearing and Settlement

The National Payments Corporation of India uses “clearing and settlement”, to ensure a smooth transfer of funds between banks. Debiting the sender’s account with RBI and crediting through the recipient bank is part of clearing and settlement internally at the IMPS network. This mechanism helps transfer funds in a developed, safe, and secure manner and keeps the records updated between the participating banks.

3.7 Crediting Beneficiary

The beneficiary bank receives the credit message from NPCI and promptly credits the designated amount to the recipient’s account.

3.8 Confirmation

Both the sender and the beneficiary receive confirmation messages stating the successful transfer, ensuring transparency and peace of mind.

4. Security Measures

1. Encryption

The IMPS network integrates secure protocols like Secure Sockets Layer (SSL) or Transport Layer Security (TLS) for encrypted information communication between the parties. Such a data transmission process ensures the data’s confidentiality and integrity, preventing any unauthorised access and interception.

2. Two-Factor Authentication

Two-Factor Authentication requires additional credentials such as mobile MPIN or OTP to perform any transaction, making the account more secure.

3. Message Authentication

Digital Signatures or Message Authentication Codes are used to ensure the integrity of the messages being sent and received and avoid tampering. This makes it more safe and secure.

IMPS Limit Per Day

The daily threshold for IMPS transactions in India stands at ₹5 lakh. Individuals can transfer this amount using internet banking, mobile banking or via their account number. Adhering to this information is crucial for the business’s steady financial process.

Initially, the Reserve Bank of India restricted the IMPS limit per day to ₹2 lakh. However, considering the increasing demand for this payment system, the RBI increased the daily limit for IMPS to ₹5 lakh to meet the growing demand of users and businesses.

IMPS Charges as of 2024

The following are the charges applicable for IMPS, excluding applicable Goods and Service Tax (GST). ₹2.5 will be charged for transactions up to ₹10,000, ₹5 for transactions between ₹10,001–₹1 lakh, and ₹15 for transactions between ₹1 lakh–₹2 lakh.

IMPS Transfer Time

IMPS operates around the clock, 24/7 for every account holder of any bank. Funds are swiftly transferred to the beneficiary instantly upon approval of the transaction by the sender’s bank. However, in rare instances, such as when a transaction becomes void, fails, or times out during the process, resolution may take up to 5 working days.

IMPS Transaction Essentials and Involved Parties

To make a successful transaction, a few requirements need to be met. To begin with, the mobile number needs to be registered with the bank and the user needs to access essential mobile banking services. After registration, the MMID and the MPIN number are provided by a bank.

The Mobile Money Identifier (MMID) is a 7-digit identification number, and the MPIN is a four-digit password that applies to mobile banking. 

Add the beneficiaries to the account, link their account details with the registered mobile number and obtain their MMID from the bank.

The beneficiary must submit an Aadhaar number, IFSC, bank account number, mobile number and MMID details to make an IMPS transaction.

IMPS transactions have three main participants and are as follows:

  • Remitter: Remitter bank/Prepaid Payment Instruments (PPI)

What Restrictions on Fund Transfers Apply to IMPS?

Compared to RTGS and NEFT, IMPS offers restrictions considering the needs of an average consumer looking to make generic payments.

Have a look at the table below to compare the differences between the three:





Minimum transaction amount ₹2 lakh ₹1 ₹1
Maximum transaction amount No upper limit has been placed on RTGS transactions Transaction limits vary from bank to bank Transaction limits vary from bank to bank


As you can see, while RTGS and NEFT may have higher upper limits, IMPS will most likely serve consumers looking to meet their daily transaction needs. The low minimum transaction amount means users can use this system to pay bills at local Kirana (if the vendor allows), shop through apps on mobile phones or send money to the family.

Of course, NEFT and RTGS may be the way to go for sending exorbitant amounts of money. The downside will be the time constraints one must operate within.


We hope this article has helped in understanding what is IMPS in bank. IMPS has changed consumer behaviour and expectations and paved the way for newer forms of instant payment systems to operate in India. The fact that consumers can use this system without needing a smartphone adds to its financial inclusivity, making it a great payment option for the masses!
