Payment Systems in India: BBPS, IMPS, NEFT, RTGS, UPI, BHIM, AePS and RuPay

India has developed a wide range of digital and electronic payment systems that make it easier for people to transfer money, pay bills, purchase products and access basic banking services. From traditional bank transfers such as NEFT and RTGS to mobile-based payments through UPI and BHIM, digital payments have become an important part of everyday banking.

Several payment systems are operated or supported by major institutions such as the Reserve Bank of India (RBI) and the National Payments Corporation of India (NPCI). Each system has a different purpose. For example, NEFT is commonly used for electronic fund transfers, RTGS is designed for real-time high-value transfers, IMPS enables instant transfers, and UPI allows users to make quick bank-to-bank payments using mobile applications.

Other systems such as *Bharat Bill Payment System (BBPS), Aadhaar Enabled Payment System (AePS), RuPay and 99# serve different payment and banking requirements.

What Are Payment Systems in India?

A payment system is a mechanism through which money can be transferred from one person, bank account or organisation to another.

Payment systems can be used for activities such as:

• Sending money to another bank account
• Receiving payments
• Paying electricity and water bills
• Paying telephone and mobile bills
• Making online purchases
• Paying merchants
• Withdrawing cash through banking agents
• Checking bank balances
• Making recurring payments
• Transferring money through mobile phones

The Indian payment ecosystem includes both bank-based and digital payment platforms. Some systems work through bank accounts, while others use mobile numbers, UPI IDs, Aadhaar authentication, cards or other identifiers.

Major Payment Systems in India

Some of the important payment systems in India include:

1. Bharat Bill Payment System (BBPS)
2. Immediate Payment Service (IMPS)
3. National Electronic Funds Transfer (NEFT)
4. Real Time Gross Settlement (RTGS)
5. Unified Payments Interface (UPI)
6. Bharat Interface for Money (BHIM)
7. Aadhaar Enabled Payment System (AePS)
8. BHIM Aadhaar Pay
9. RuPay
10. *99# USSD Banking

Let’s understand each of these payment systems in detail.

1. Bharat Bill Payment System (BBPS)

The Bharat Bill Payment System (BBPS) is an interoperable bill payment system designed to provide a convenient way to pay different types of bills through a common platform.

The system was introduced to make bill payments easier and more accessible. It can be used for different categories of bills and services through digital as well as physical customer touchpoints.

The RBI introduced the original BBPS framework in 2014. The regulatory framework was subsequently revised through the RBI’s Bharat Bill Payment System Directions, 2024, which came into effect from April 1, 2024. Under the current framework, NPCI Bharat BillPay Limited (NBBL) is the authorised Payment System Provider for BBPS.

BBPS is also commonly associated with the Bharat Connect brand in the evolving bill-payment ecosystem.

What Can Be Paid Through BBPS?

Depending on the biller and available service, users can make payments for categories such as:

• Electricity bills
• Water bills
• Telephone bills
• Mobile bills
• Gas bills
• DTH services
• Other utility and service bills

The system is designed to provide an interoperable bill-payment experience, allowing customers to access bill-payment services through participating digital and physical channels.

Advantages of BBPS

Some important advantages include:

• Convenient bill payment
• Interoperable payment infrastructure
• Digital and physical access points
• Standardised bill-payment experience
• Customer grievance redressal framework
• Multiple payment channels

BBPS has therefore become an important part of India’s retail payment infrastructure.

2. Immediate Payment Service (IMPS)

Immediate Payment Service (IMPS) is a real-time electronic fund transfer service operated by NPCI.

It allows customers to transfer money instantly through participating banks and authorised channels. One of its major advantages is that it operates 24 hours a day, seven days a week, including holidays.

IMPS can be accessed through different channels, including:

• Mobile banking
• Internet banking
• ATMs
• Other supported banking channels

Main Features of IMPS

Important features of IMPS include:

• Instant money transfer
• 24×7 availability
• Mobile and internet banking support
• Interbank fund transfer
• Confirmation through banking channels
• Convenient electronic payment facility

The current NPCI information states that the standard IMPS per-transaction limit is ₹5 lakh for channels other than SMS and IVR, although customers should check their individual bank’s applicable limits.

Why Is IMPS Useful?

IMPS is particularly useful when a person needs to transfer money immediately instead of waiting for a batch-based settlement.

For example, if you need to send money to another bank account outside normal branch working hours, IMPS can be a convenient option, subject to the bank’s rules and transaction limits.

3. National Electronic Funds Transfer (NEFT)

National Electronic Funds Transfer (NEFT) is an electronic fund transfer system operated by the Reserve Bank of India.

NEFT allows customers to transfer funds from one bank account to another NEFT-enabled bank account. Unlike RTGS, NEFT traditionally worked through batches rather than processing each transaction individually in real time.

However, NEFT is now available 24x7x365. RBI states that NEFT operates through 48 half-hourly settlement batches throughout the day.

Important Features of NEFT

NEFT offers:

• Electronic bank-to-bank money transfer
• 24x7x365 availability
• No minimum amount requirement
• No maximum amount prescribed by RBI for normal NEFT transactions
• Online and branch-based access, depending on the bank
• Wide availability across Indian banks

Banks may impose their own transaction limits or security controls, particularly for online banking.

NEFT vs Traditional Money Transfer

Before electronic fund-transfer systems became widespread, customers often had to depend on physical instruments or visit bank branches to transfer money.

NEFT made electronic bank transfers more convenient by allowing customers to initiate transactions through banking channels without physically moving money or paper instruments.

4. Real Time Gross Settlement (RTGS)

Real Time Gross Settlement (RTGS) is a payment system used for transferring funds on a real-time and gross basis.

“Real time” means transactions are processed continuously without waiting for batch settlement. “Gross settlement” means each transaction is settled individually rather than being bundled with other transactions.

Once an RTGS transaction is processed and settled, the settlement is final and irrevocable under the system framework.

RBI states that RTGS is available 24x7x365, with effect from December 14, 2020.

RTGS Minimum Amount

RTGS is generally intended for high-value transactions.

The RBI-prescribed minimum amount for customer RTGS transactions is ₹2 lakh, while there is no maximum limit prescribed by RBI. Banks may, however, set their own limits for particular channels based on their policies.

Main Features of RTGS

• Real-time processing
• Individual transaction settlement
• Minimum transaction amount of ₹2 lakh
• 24x7x365 availability
• Suitable for high-value fund transfers
• Settlement is final and irrevocable

NEFT vs RTGS

The basic difference is the way transactions are processed.

NEFT uses a batch-based settlement mechanism, while RTGS settles transactions individually on a real-time basis. RBI describes NEFT as a retail payment system and RTGS as a real-time gross settlement system.

5. Unified Payments Interface (UPI)

The Unified Payments Interface (UPI) has transformed the way people make everyday digital payments in India.

UPI allows users to connect multiple bank accounts through a compatible mobile application and make instant bank-to-bank payments. NPCI states that UPI is built over the IMPS infrastructure and enables instant transfers between bank accounts.

Instead of entering lengthy bank details for every transaction, users can generally make payments using a UPI ID, QR code or other supported payment method.

Key Features of UPI

UPI provides features such as:

• Instant bank-to-bank transfers
• 24×7 availability
• UPI ID-based payments
• QR code payments
• Merchant payments
• Person-to-person transfers
• Collect requests
• Recurring payments through supported UPI mandates
• Multiple bank accounts through compatible apps

One of the major benefits of UPI is convenience. A customer can pay a shopkeeper by scanning a QR code instead of using cash.

How Does UPI Work?

Suppose you purchase an item from a shop.

The merchant may display a UPI QR code. You scan the code using your UPI-enabled application, enter the amount and authorise the payment with your UPI PIN.

The money is transferred electronically from your linked bank account to the recipient’s account.

The UPI PIN should always be kept confidential. NPCI specifically advises users not to share their UPI PIN with anyone.

6. Bharat Interface for Money (BHIM)

BHIM, which stands for Bharat Interface for Money, is a UPI-based payment application developed by NPCI.

The app allows users to make bank-to-bank payments and receive money through UPI.

BHIM supports features such as:

• Sending money
• Requesting money
• QR code payments
• UPI ID payments
• Transaction history
• Multiple linked bank accounts
• UPI PIN management
• Bill payments
• UPI AutoPay
• Complaint reporting for eligible transactions

NPCI’s current BHIM information says the app supports multiple languages and provides features such as QR payments, account-based transfers and UPI transactions.

BHIM and UPI: What Is the Difference?

UPI is the underlying payment infrastructure that enables instant bank-to-bank payments.

BHIM is a UPI-based application through which users can access those payment capabilities.

In simple words:

UPI = payment infrastructure

BHIM = a UPI-based payment app

Other banks and third-party applications can also provide UPI payment services.

7. Aadhaar Enabled Payment System (AePS)

The Aadhaar Enabled Payment System (AePS) is a bank-led model that allows customers to perform certain basic banking transactions using Aadhaar authentication through an authorised AePS touchpoint.

AePS can be particularly useful for financial inclusion because customers can access banking services through participating banking correspondents and other touchpoints.

According to NPCI, AePS supports services including:

• Cash withdrawal
• Cash deposit
• Fund transfer
• Balance enquiry
• Mini statement
• Authentication services
• BHIM Aadhaar Pay

How AePS Works

AePS transactions can involve details such as:

• Aadhaar number
• Bank name
• Transaction type
• Biometric authentication, where applicable
• Transaction amount for financial transactions

The customer provides the required information and authentication at an authorised AePS touchpoint.

The system is designed to support interoperability between participating banks and promote access to basic banking services.

8. BHIM Aadhaar Pay

BHIM Aadhaar Pay is designed to allow merchants to accept payments from customers using Aadhaar-based authentication.

It can be used at participating merchant locations where the required infrastructure and banking arrangements are available.

A typical setup can involve:

• Android mobile device
• BHIM Aadhaar Pay application
• Certified biometric scanner
• Merchant bank account
• Customer’s Aadhaar-linked bank account
• Biometric authentication

The system was designed to provide another way for customers to make merchant payments, particularly in situations where traditional card or mobile-based payment options may not be convenient.

9. RuPay

RuPay is India’s domestic card payment network developed by NPCI.

The name “RuPay” is derived from the words Rupee and Payment. RuPay cards are used for transactions at participating ATMs, point-of-sale terminals and e-commerce websites.

RuPay offers different types of cards and payment solutions, including debit, credit and prepaid card products.

Features of RuPay

Depending on the specific card, features and benefits may include:

• ATM transactions
• Point-of-sale payments
• Online shopping
• Contactless payments
• International acceptance on eligible cards
• Merchant offers
• Cashback or rewards on eligible products
• Airport lounge benefits on eligible cards
• Other card-specific benefits

RuPay also offers contactless payment technology. Users can tap a compatible card on a supported payment terminal to make a contactless transaction, subject to applicable limits and authentication requirements.

Why Is RuPay Important?

RuPay provides a domestic card payment network and has contributed to the development of India’s electronic payment infrastructure.

It also provides Indian banks and financial institutions with a domestic card network for issuing payment cards.

10. *99# USSD Banking Service

*99# is a USSD-based mobile banking service designed to provide banking services through a mobile phone without requiring mobile data connectivity.

The service uses a common USSD code, allowing customers to access supported banking services through an interactive menu.

Some services associated with *99# include:

• Sending money
• Receiving money
• Balance enquiry
• UPI-related services
• Setting or changing UPI PIN
• Bank account services

The major advantage of USSD banking is that it can work without an internet connection, making it useful for customers who have basic mobile phones or limited access to mobile data.

Difference Between NEFT, RTGS, IMPS and UPI

Many students and banking exam aspirants find it difficult to remember the differences between these payment systems. The easiest way is to understand their basic purpose.

Payment System	Main Purpose	Processing	Common Use
NEFT	Bank fund transfer	Batch-based settlement	Regular electronic transfers
RTGS	High-value fund transfer	Real-time, transaction-by-transaction	High-value transfers
IMPS	Instant fund transfer	Real-time	Immediate transfers
UPI	Mobile-based bank payments	Instant	Everyday payments
BBPS	Bill payments	Interoperable bill-payment system	Utility and service bills
AePS	Aadhaar-enabled banking	Banking through authorised touchpoints	Cash and basic banking services
RuPay	Card payments	Card network	ATM, POS and online payments
BHIM	UPI payments	Instant through UPI	Mobile payments
*99#	USSD banking	Mobile network-based	Basic banking without mobile data

The table gives a simplified overview. Actual limits, charges and available services can vary by bank, payment channel and transaction type.

Importance of Digital Payment Systems in India

Digital payment systems have changed the way individuals, businesses and institutions handle money.

A customer can now transfer money without visiting a bank branch. A small shop can accept QR-based payments. Utility bills can be paid online, while bank customers can transfer funds at any time through several digital channels.

These systems also support financial inclusion by providing different ways for people to access banking services.

For example, UPI is highly useful for smartphone-based payments, while AePS and USSD-based services can provide alternatives for customers who may not have the same level of access to smartphones or mobile data.
