Understanding CTS in India: Benefits, Process, and RBI Guidelines

Cheque Truncation System (CTS) is an image-based cheque clearing system that replaces the flow of physical cheques with digital images and Magnetic Ink Character Recognition (MICR) data. In simple terms, when you deposit a cheque, your bank scans it, generates an encrypted image, and transmits it to the clearing house—eliminating the need to move the paper instrument.

RBI explains that truncation means stopping the flow of the physical cheque at the presenting bank and replacing it with electronic images and MICR data. 

This shift was necessary to:

• Speed up cheque clearing timelines.
• Reduce costs of physical handling.
• Enhance security and fraud detection through image-based scrutiny.

The Evolution: From MICR to CTS

Traditional MICR Clearing System

Prior to CTS implementation, as documented by NPCI, the traditional system operated through 66 MICR centers across India. The process involved:

• Physical transportation of cheques to respective MICR clearing centres
• Local clearing for same-city transactions
• Outstation clearing for inter-city transactions
• Extended settlement cycles ranging from T+2 to T+10 days
• High operational costs and risks associated with physical movement

CTS Implementation Timeline

The transformation to CTS occurred in phases:

• February 1, 2008: CTS launched in New Delhi
• September 24, 2011: Chennai grid implementation
• April 27, 2013: Mumbai grid implementation
• December 31, 2018: Complete discontinuation of non-CTS cheque clearing

How Does CTS Work?

The Cheque Truncation System (CTS) has transformed the way cheques are cleared in India by replacing the movement of physical cheques with secure digital images and data. This makes the process faster, safer, and more reliable. Let’s walk through the entire flow step by step:

Step 1: Capturing cheque details at the presenting bank

When a customer deposits a cheque at their bank (called the presenting bank), the bank captures key information from the cheque.

• The details on the MICR band (Magnetic Ink Character Recognition line) are scanned.
• A high-quality image of the cheque is also captured using scanners and cheque-processing software that comply with RBI and NPCI specifications.

This step ensures that both the image and data of the cheque are available for electronic transmission.

Step 2: Digital signing and encryption for security

Security is crucial in digital cheque clearing. To guarantee authenticity and prevent fraud, CTS uses a Public Key Infrastructure (PKI) framework.

• The presenting bank digitally signs and encrypts the cheque image and data.
• This ensures that the information cannot be tampered with in transit and also provides proof of origin (non-repudiation).

Step 3: Transmission to the Clearing House

Once encrypted, the data and images are sent to the Centralised Clearing House (CCH), which is managed by NPCI (National Payments Corporation of India) under RBI’s oversight.

• Banks use either the Clearing House Interface (CHI) or a Data Exchange Module (DEM) to securely connect to the CCH.
• At this stage, the CCH acts as the digital hub for cheque processing, replacing the old system where physical cheques had to travel across locations.

Step 4: Processing at the Clearing House

The CCH verifies and processes the data to determine settlement positions of banks.

• The cheque images and data are forwarded to the respective paying banks (also called drawee banks).
• This step is known as presentation clearing, as it involves presenting the cheque details for payment.

Step 5: Validation by the Paying Bank

The paying bank receives the cheque data and image through its CHI/DEM and undertakes further verification.

• The bank checks account balance, signature authenticity, and any potential issues with the cheque.
• If everything is in order, the payment is cleared.

If a cheque cannot be honoured (e.g., due to insufficient funds, signature mismatch, or stop-payment instructions), the paying bank generates a return file.

Step 6: Return clearing

The return file created by the paying bank is sent back to the Clearing House.

• The Clearing House processes these unpaid items in a return clearing session, similar to presentation clearing.
• This data is then routed back to the presenting banks, which informs the customers accordingly.

Step 7: Completion of the clearing cycle

The cycle is considered complete once both presentation clearing and return clearing sessions are successfully executed. At this point:

• Funds are settled between banks.
• Customers receive either the credited amount (if cleared) or the cheque return information (if dishonoured).

What is the status of CTS implementation in India?

The Cheque Truncation System (CTS) has been successfully rolled out across the country in a phased manner. It was first launched in New Delhi (February 1, 2008), followed by Chennai (September 24, 2011), and Mumbai (April 27, 2013). With this nationwide migration, the traditional paper-based clearing mechanisms have been discontinued, making cheque clearance faster, more secure, and uniform across India.

To strengthen efficiency, CTS operations in India are consolidated into three major grids—Chennai, Mumbai, and New Delhi. Each grid provides end-to-end cheque processing and settlement services to all banks falling under its jurisdiction. This grid-based model ensures that even banks and branches located in remote or smaller towns can benefit from seamless and modern cheque clearing without the need for local clearing houses.

Jurisdiction of CTS Grids in India

“One Nation, One Grid” Initiative

The RBI has outlined plans for the “One Nation, One Grid” project, which aims to merge the three existing grids into a single national grid, providing:

• Faster realization of outstation cheques
• Improved fund management for banks
• Streamlined infrastructure
• Overall efficiency improvements

What Type of Instruments Can Be Presented for Clearing Through CTS?

Only CTS-2010 standard compliant cheques and instruments can be presented in the Cheque Truncation System (CTS).

The CTS-2010 standards were introduced by the Reserve Bank of India (RBI) to ensure uniformity and better security in cheque-based transactions across all banks in the country. These standards include:

• Paper Quality – Cheques must be printed on paper with specified durability.
• Watermark – Every cheque carries a standardized watermark for authenticity.
• Bank’s Logo in Invisible Ink – Helps prevent counterfeiting.
• Void Pantograph – Displays the word “VOID” if a cheque is photocopied, ensuring protection against duplication.
• Standard Field Placement – Date, payee name, amount, signature, and MICR code are placed in predefined areas, making machine reading and verification easier.

These features not only enhance security but also make image-based processing smoother, reducing errors during cheque clearing.

What Are the Precautions Required to Be Taken by Banks in CTS?

For CTS to function effectively, banks are required to follow certain precautions while handling cheques:

1. Proper Use of Stamps – Banks must ensure that official stamps or endorsements do not overlap important details like date, payee name, amount, or signature.
2. Clarity of Cheque Image – Cheques should be scanned in such a way that all key features are clearly visible in the electronic image.
3. Maintaining Security Features – Apart from mandatory CTS-2010 features, some banks also add extra security measures voluntarily (e.g., unique designs or additional inks). These too must be verified during processing.
4. Customer Awareness – Customers must be careful not to fold, staple, or damage cheques in ways that obscure essential details, as this may affect scanning and clearance.

Positive Pay System (PPS) for Enhanced Security

Implementation Guidelines

The RBI has introduced the Positive Pay System as an additional security measure:

Mandatory Requirements:

• Mandatory for cheques of ₹5,00,000 and above
• Optional for cheques of ₹50,000 and above

Process:

• Account holder provides key cheque details before issuance
• Details include cheque number, date, payee name, and amount
• Bank cross-verifies information before payment processing
• Additional fraud prevention layer

CTS Best Practices: Do’s & Don’ts 

Source: NPCI

Do’s (What you should do)

• Use only CTS-2010 standard cheques: Look for the “CTS-2010” mark printed on the left side of the cheque.
• Write clearly using permanent ink: Always use a ball-pen and fill in details (beneficiary, date, amount in words & figures) in one go yourself.
• Format amount and beneficiary carefully: Start the amount in words close to the “Rupees” label, end with “only,” write figures close to the “₹” box with “/-” afterward, and strike through unused spaces in name and amount fields to prevent tampering.
• Sign within the designated space: Ensure your signature is clear and placed in the allotted spot.
• Handle cheque books securely: Do not remove cheques without your knowledge, destroy spoiled cheques completely, and keep cheque books in safe, locked storage.
• Act promptly in case of discrepancies: If cheques are missing from your chequebook or your bank statement shows anomalies, report immediately and request a stop payment.
• Maintain sufficient account balance: Always ensure funds are available before issuing a cheque. For cancellations, write “CANCELLED” visibly across the cheque.

Don’ts (What you shouldn’t do)

• Do not write below the MICR band: Avoid any writing over the bottom 5/8-inch MICR line—it’s essential for accurate cheque sorting and processing.
• Never sign blank cheques: Signing or handing over blank cheques risks misuse.
• Avoid erasable pens or pencils: Use only permanent ink—erasable writing is prone to tampering.
• Do not fold, pin, or staple cheques: Folding or stapling can distort crucial details and interfere with image capture.
• Refrain from making alterations: Never amend or erase existing text on a cheque. Any corrections should be handled according to bank guidelines.

New Developments: Continuous Clearing

The RBI has introduced a transformative upgrade to India’s cheque-clearing infrastructure: transitioning CTS from traditional batch processing to a continuous clearing and settlement on realization model. This major reform will roll out in two phases:

Single Presentation Session with Continuous Delivery

• There will be one presentation window daily: 10:00 AM to 4:00 PM.
• During this period, cheques deposited at branches will be scanned and transmitted immediately to the clearing house, instead of being held and sent in bulk.
• The clearing house (operated by NPCI under RBI oversight) will then release cheque images continuously to the respective drawee banks for processing.

Continuous Inward Processing & Confirmation by Drawee Banks

• Drawee banks must process cheques as they arrive, in real time, from 10:00 AM until 7:00 PM.
• For each cheque, they must send either:
  Positive confirmation – cheque honoured
  Negative confirmation – cheque dishonoured
• Each cheque is tagged with an “Item Expiry Time”, i.e., the last permissible moment for confirmation.
• Confirmation must be transmitted back immediately after processing, so that settlements can take place without delay.

Time Available for Inward Processing (Two Phases)

• Phase 1 (Oct 4, 2025 – Jan 2, 2026):
  • All cheques must be confirmed (positive/negative) by 7:00 PM.
  • Cheques not confirmed by then will be treated as deemed approved and included in settlement.
    
• Phase 2 (From Jan 3, 2026):
  • The expiry time changes to “T+3 clear hours”.
  • Example: If a cheque is received at 10:15 AM, it must be confirmed by 1:15 PM (3 hours later).
  • Any cheque not confirmed within 3 hours will automatically be deemed approved and settled at the expiry time.

Settlement on Realisation

• Unlike the old system, no settlement entries are made when cheques are presented.
• Instead, settlements are carried out hourly from 11:00 AM until 7:00 PM, based on:
  • Cheques with positive confirmation, and
  • Cheques deemed approved due to no response.
• Cheques with negative confirmation are excluded from settlement.

Releasing Payment to Customers

• Once each hourly settlement is complete, the clearing house sends back the results (positive or negative) to the presenting bank.
• The presenting bank is required to credit customers’ accounts immediately, but no later than one hour after receiving settlement results, subject to the usual checks.

This step is expected to bring cheque processing closer to real-time settlement, aligning it with India’s vision of faster, technology-driven banking. RBI Press Release
