Payment Systems in India: NEFT, RTGS and IMPS Notes
Banking awareness notes on NEFT, RTGS and IMPS: operators, settlement methods, limits, the 2007 Act, the NPCI products and the IFSC, MICR and MMID codes.
By GK24 Editorial Team· Published · 4 min read

Every rupee that moves from one bank account to another in India travels through a payment system, and banking awareness papers test three of them by name: RTGS, NEFT and IMPS. The three differ in who runs them, how quickly they settle, and what they cost the customer. Learn them as a comparison rather than one by one, because almost every question is set by swapping one feature of one system for another.
The legal and institutional framework
The Payment and Settlement Systems Act of 2007 made the Reserve Bank of India the authority for regulating and supervising payment systems, and no payment system may be operated in India without its authorisation. The Board for Regulation and Supervision of Payment and Settlement Systems works under the Reserve Bank for this purpose. Alongside it stands the National Payments Corporation of India, set up in 2008 as an umbrella organisation for retail payments, promoted by the Reserve Bank and the Indian Banks Association and registered as a not for profit company. RTGS and NEFT are operated by the Reserve Bank itself; IMPS, UPI, RuPay, NACH, AEPS, BBPS and FASTag are all products of the National Payments Corporation of India.
The three systems compared
| Feature | RTGS | NEFT | IMPS |
|---|---|---|---|
| Full form | Real Time Gross Settlement | National Electronic Funds Transfer | Immediate Payment Service |
| Operated by | Reserve Bank of India | Reserve Bank of India | National Payments Corporation of India |
| Settlement | Transaction by transaction, in real time | Deferred net settlement, in half hourly batches | Immediate, round the clock |
| Minimum amount | Two lakh rupees | No minimum | No minimum |
| Availability | All days of the year since December 2020 | All days of the year since December 2019 | All days of the year since it began |
| Identifiers used | Account number and IFSC | Account number and IFSC | Account number and IFSC, or mobile number and MMID |
What gross and net settlement mean
Gross settlement means that each instruction is settled by itself, one at a time, the moment it is processed; that is why RTGS is used for large payments, where waiting even an hour carries a risk. Net settlement means that the system collects instructions for a period, sets off what banks owe each other and settles only the difference; NEFT works this way, in half hourly batches through the day, which is efficient for a large number of small payments. Real time means the settlement is final and irrevocable as soon as it is done, and this finality is the reason the Reserve Bank keeps RTGS for amounts of two lakh rupees and above, with no upper limit set by the Reserve Bank itself.
IMPS, UPI and the retail systems
IMPS was launched by the National Payments Corporation of India in 2010 and was the first Indian system to offer instant interbank transfer at any hour of any day, including holidays, long before RTGS and NEFT were made available round the clock. It can be used through mobile banking, internet banking and ATMs. A customer may send money either with the beneficiary's account number and IFSC or with the beneficiary's mobile number and a seven digit Mobile Money Identifier issued by the bank. The Reserve Bank raised the per transaction ceiling for IMPS to five lakh rupees in 2021. The Unified Payments Interface, launched in 2016, builds on the same immediate settlement rails and adds a virtual payment address so that a payer need not know the account number at all. Other systems worth naming are NACH for bulk credits such as salary and subsidy, AEPS for withdrawals authenticated by Aadhaar and fingerprint, the Bharat Bill Payment System for utility bills, the National Electronic Toll Collection system behind FASTag, and the Cheque Truncation System, under which the image of a cheque rather than the paper itself moves for clearing.
The codes a candidate must know
- IFSC, the Indian Financial System Code, has eleven characters: the first four letters identify the bank, the fifth is always zero and is kept for future use, and the last six identify the branch. It is used in RTGS, NEFT and IMPS.
- MICR, the Magnetic Ink Character Recognition code printed at the foot of a cheque, has nine digits: three for the city, three for the bank and three for the branch.
- MMID, the Mobile Money Identifier used in IMPS, has seven digits, of which the first four identify the bank.
- SWIFT codes, of eight or eleven characters, are used for payments across borders, not within India.
On charges, the Reserve Bank stopped levying its own charges on banks for RTGS and NEFT in July 2019 and asked banks to pass the benefit on, and banks were directed not to charge savings account holders for NEFT transfers made online. This is a favourite question because candidates assume a high value transfer must cost more.
Exam Point of View
Banking papers ask this topic as a comparison. The most frequent question is the minimum for RTGS, where two lakh rupees is the answer and one lakh the trap. Next come the expansions of the three abbreviations, asked together in one question. Then the operator, where the safe rule is that the Reserve Bank runs only RTGS and NEFT and the National Payments Corporation of India runs everything else named here. Settlement questions turn on the words gross and net: gross means one by one in real time, net means batched and set off. The codes are asked as a set, so learn eleven for IFSC, nine for MICR and seven for MMID together. Years are worth carrying too: the Act in 2007, the corporation in 2008, IMPS in 2010, RuPay in 2012, UPI in 2016, round the clock NEFT in 2019 and round the clock RTGS in 2020.

Practice MCQs on this topic
What is the minimum amount that can be remitted through RTGS?
- A.Ten thousand rupees
- B.One lakh rupees
- C.Two lakh rupees
- D.Five lakh rupees
Show answer
Correct answer: C. Two lakh rupees
Explanation
The correct answer is C, two lakh rupees. RTGS is meant for large value payments, and the Reserve Bank has fixed a floor of two lakh rupees for a remittance through it, while setting no ceiling of its own on the amount. Option A is wrong because a transfer of ten thousand rupees would go through NEFT, IMPS or UPI, none of which has a minimum. Option B is wrong because one lakh rupees is below the floor and would be refused by the system. Option D is wrong because five lakh rupees is well above the floor and can certainly be sent by RTGS; it is the figure to which the Reserve Bank raised the per transaction ceiling for IMPS in 2021, which is why it appears as a distractor here. Fix the pairing in memory: RTGS has a minimum and no maximum, while NEFT and IMPS have no minimum at all.
NEFT stands for:
- A.National Electronic Funds Transfer
- B.New Electronic Fund Transaction
- C.National Exchange of Funds and Transfers
- D.Net Electronic Financial Transfer
Show answer
Correct answer: A. National Electronic Funds Transfer
Explanation
The correct answer is A, National Electronic Funds Transfer. NEFT is the nationwide system operated by the Reserve Bank of India for transferring funds from one bank account to another, settled on a deferred net basis in half hourly batches and available on all days of the year since December 2019. Options B, C and D are wrong because they are invented expansions of the same four letters, and none of them is used in any Reserve Bank circular; papers build such options because a candidate who has only heard the abbreviation spoken will not have seen it written out. Remember the three expansions together, since they are often asked in one question: RTGS is Real Time Gross Settlement, NEFT is National Electronic Funds Transfer and IMPS is Immediate Payment Service.
In which payment system is each transaction settled individually and in real time, without being grouped into batches?
- A.NEFT
- B.RTGS
- C.NACH
- D.Cheque Truncation System
Show answer
Correct answer: B. RTGS
Explanation
The correct answer is B, RTGS. The words in the name say it: real time means the instruction is carried out as it is received, and gross settlement means each instruction is settled by itself rather than set off against others. Settlement is final and irrevocable once done, which is what a large value payment needs. Option A is wrong because NEFT works on deferred net settlement, collecting instructions and settling the net position in half hourly batches. Option C is wrong because NACH is a bulk clearing system for repeated credits and debits such as salary, pension, subsidy and instalments, which is the opposite of transaction by transaction settlement. Option D is wrong because the Cheque Truncation System clears cheques in sessions by sending their images, again in batches. Gross with RTGS and net with NEFT is the distinction papers test most often.
The Immediate Payment Service (IMPS) is operated by:
- A.The Reserve Bank of India
- B.The State Bank of India
- C.The National Payments Corporation of India
- D.The Indian Banks Association
Show answer
Correct answer: C. The National Payments Corporation of India
Explanation
The correct answer is C, the National Payments Corporation of India. IMPS was launched by that organisation in 2010 and was the first Indian system to offer interbank transfer instantly at any hour, including Sundays and holidays. Option A is wrong because the Reserve Bank operates RTGS and NEFT but not IMPS, although it regulates every payment system under the Payment and Settlement Systems Act of 2007. Option B is wrong because the State Bank of India is a member bank of the system, not its operator. Option D is wrong because the Indian Banks Association, along with the Reserve Bank, promoted the National Payments Corporation of India but does not run the service itself. Group the products by owner: RTGS and NEFT with the Reserve Bank, and IMPS, UPI, RuPay, NACH, AEPS, BBPS and FASTag with the National Payments Corporation of India.
How is a NEFT transaction settled?
- A.Individually, the moment it is received
- B.On a deferred net basis, in half hourly batches
- C.Only at the end of the working day
- D.Only after the beneficiary bank confirms it
Show answer
Correct answer: B. On a deferred net basis, in half hourly batches
Explanation
The correct answer is B, on a deferred net basis, in half hourly batches. NEFT holds instructions for a short period, works out what each bank owes the others on balance, and settles only that difference; the batches run every half hour through all twenty four hours, since the service was made available on all days of the year in December 2019. Option A is wrong because settling each instruction the moment it arrives is the method of RTGS, not NEFT. Option C is wrong because a single settlement at the close of the day was the practice of older clearing arrangements and was never how NEFT worked. Option D is wrong because settlement between the banks is not made to wait for a confirmation from the beneficiary bank, although the credit to the customer's account does follow the settlement. Net settlement in batches is the phrase to carry into the hall.
An IFSC used for electronic funds transfer in India consists of how many characters?
- A.Nine
- B.Ten
- C.Eleven
- D.Twelve
Show answer
Correct answer: C. Eleven
Explanation
The correct answer is C, eleven. The Indian Financial System Code is made of eleven characters: the first four letters stand for the bank, the fifth is always the digit zero and is kept in reserve for future use, and the last six identify the particular branch. It is required for RTGS, NEFT and for an IMPS transfer made with an account number. Option A is wrong because nine is the length of the MICR code printed on a cheque, which is made of three digits each for the city, the bank and the branch. Option B is wrong because no Indian banking code has ten characters. Option D is wrong because twelve is the length of an Aadhaar number, which is used in the Aadhaar Enabled Payment System but is not a bank branch code. Papers mix IFSC, MICR and MMID in one question, so learn eleven, nine and seven together.
Under which Act does the Reserve Bank of India regulate and supervise payment systems in the country?
- A.The Banking Regulation Act, 1949
- B.The Payment and Settlement Systems Act, 2007
- C.The Negotiable Instruments Act, 1881
- D.The Reserve Bank of India Act, 1934
Show answer
Correct answer: B. The Payment and Settlement Systems Act, 2007
Explanation
The correct answer is B, the Payment and Settlement Systems Act, 2007. This Act designates the Reserve Bank as the authority for payment systems, makes its authorisation necessary before any payment system may be operated, and provides for the Board for Regulation and Supervision of Payment and Settlement Systems. Option A is wrong because the Banking Regulation Act of 1949 governs the licensing, management and business of banking companies. Option C is wrong because the Negotiable Instruments Act of 1881 deals with cheques, bills of exchange and promissory notes, and it is under its section 138 that a dishonoured cheque becomes an offence. Option D is wrong because the Reserve Bank of India Act of 1934 established the Reserve Bank itself and deals with currency and monetary matters. The year 2007 for payments and 1881 for cheques are the two dates worth fixing.
The Unified Payments Interface (UPI) was launched by the National Payments Corporation of India in which year?
- A.2010
- B.2012
- C.2016
- D.2019
Show answer
Correct answer: C. 2016
Explanation
The correct answer is C, 2016. UPI was launched in 2016 and allows a customer to pay from a bank account using a virtual payment address, so that the account number and the IFSC need never be shared; it runs on the same immediate settlement arrangement that IMPS introduced. Option A is wrong because 2010 is the year IMPS itself was launched. Option B is wrong because 2012 is the year the RuPay card network was launched by the same organisation. Option D is wrong because 2019 is the year in which NEFT was made available on all days of the year and the Reserve Bank did away with its own charges on RTGS and NEFT. A short timeline is worth memorising: the corporation in 2008, IMPS in 2010, RuPay in 2012, UPI in 2016, NEFT round the clock in 2019 and RTGS round the clock in 2020.
The MICR code printed at the bottom of a cheque leaf consists of how many digits?
- A.Six
- B.Seven
- C.Nine
- D.Eleven
Show answer
Correct answer: C. Nine
Explanation
The correct answer is C, nine. The Magnetic Ink Character Recognition code has nine digits, of which the first three stand for the city, the next three for the bank and the last three for the branch; it is printed in magnetic ink so that a sorting machine can read it during cheque clearing. Option A is wrong because six digits make up only the branch part of an IFSC, not a code by itself. Option B is wrong because seven is the length of the MMID used in IMPS, whose first four digits identify the bank. Option D is wrong because eleven is the length of the IFSC, which is alphanumeric rather than numeric. Note also that with the Cheque Truncation System the image of the cheque now travels for clearing rather than the paper, although the MICR line is still read from that image.
Which of the following is the correct pairing of a payment system with the body that operates it?
- A.RTGS - National Payments Corporation of India
- B.NEFT - Indian Banks Association
- C.NACH - National Payments Corporation of India
- D.UPI - Reserve Bank of India
Show answer
Correct answer: C. NACH - National Payments Corporation of India
Explanation
The correct answer is C, NACH and the National Payments Corporation of India. The National Automated Clearing House is a bulk clearing service of that corporation, used for repeated credits such as salary, pension, dividend and subsidy and for repeated debits such as loan instalments and utility bills. Option A is wrong because RTGS is operated by the Reserve Bank of India itself. Option B is wrong because NEFT is also operated by the Reserve Bank; the Indian Banks Association only helped promote the corporation and runs no payment system of its own. Option D is wrong because UPI belongs to the National Payments Corporation of India, not to the Reserve Bank, although the Reserve Bank regulates it like every other system. The safe rule is that the Reserve Bank runs exactly two of the systems named in this topic, RTGS and NEFT, and the corporation runs the rest.
Frequently Asked Questions
What is the main difference between RTGS and NEFT?
RTGS settles each transaction on its own and in real time, so the transfer is final the moment it is processed, and it carries a minimum of two lakh rupees. NEFT collects instructions and settles the net position between banks in half hourly batches, and it has no minimum or maximum amount. In short, RTGS is for large value payments and NEFT for payments of any size.
Can money be sent through NEFT or RTGS on a Sunday or a bank holiday?
Yes. NEFT has been available on all days of the year since December 2019 and RTGS since December 2020, so both work on Sundays and holidays. Before that, IMPS was the only system that worked at all hours on all days, which is why it became popular for urgent small transfers.
Is there a charge for sending money through NEFT?
The Reserve Bank stopped levying its own charges on banks for RTGS and NEFT in July 2019 and asked banks to pass the benefit to customers, and banks were directed not to charge savings account holders for NEFT transfers made through internet or mobile banking. Charges may still apply for transfers made at a branch counter.
What is the difference between IMPS and UPI?
IMPS, launched in 2010, is the underlying service for instant interbank transfer, used with an account number and IFSC or with a mobile number and MMID. UPI, launched in 2016, is an interface built on the same immediate settlement arrangement that lets a customer pay from any of several accounts using a virtual payment address, without sharing account details.
What do the characters of an IFSC mean?
An IFSC has eleven characters. The first four letters identify the bank, the fifth character is always the digit zero and is kept for future use, and the last six characters identify the branch. It is required for RTGS and NEFT and for an IMPS transfer made using the account number.
