‘OneTag’ FASTag Portability Service
Introduction
India’s digital public infrastructure is steadily moving beyond payments and identity to transform the everyday experience of mobility. The launch of ‘OneTag’, a FASTag portability service available through the National Highways Authority of India’s Rajmargyatra app, is an important step in this direction. It allows a vehicle owner to change the FASTag issuer bank without removing the existing FASTag sticker or obtaining a new physical tag. The existing Tag ID and vehicle registration number remain unchanged after portability.
The initiative, launched by Union Minister for Road Transport and Highways Nitin Gadkari at the Global Fintech Fest 2026 in Mumbai, has been developed jointly by Indian Highways Management Company Limited and the National Payments Corporation of India. Its significance lies not merely in the convenience of changing a bank. OneTag addresses a deeper issue in India’s digital tolling ecosystem: the gap between interoperability in principle and portability in practice.
FASTag has already transformed toll collection. With more than 13 crore FASTags issued and over 98% penetration in National Highway user-fee collection, electronic tolling has become central to India’s highway infrastructure. Yet users who were dissatisfied with their issuer, faced service-related difficulties, or wished to shift to another financial institution had to close the existing tag and obtain a fresh one. OneTag seeks to make the issuer a replaceable service provider while preserving the identity of the vehicle-linked tolling instrument.
The reform may appear modest, but it carries implications for consumer choice, competition among banks, lifecycle management of digital devices, administrative efficiency, data governance, and the future of barrier-free tolling.
What is OneTag?
FASTag is an RFID-based electronic toll collection system affixed to a vehicle’s windscreen. When the vehicle passes through a toll plaza, the RFID reader identifies the tag and the toll amount is deducted from a linked prepaid wallet or bank account. The system reduces cash handling, vehicle queues and manual intervention.
Earlier, the FASTag ecosystem followed a relatively rigid model. If a user wanted to change the issuer bank, the existing FASTag generally had to be closed and a new tag obtained. This created several practical problems:

What is OneTag?
FASTag is an RFID-based electronic toll collection system affixed to a vehicle’s windscreen. When the vehicle passes through a toll plaza, the RFID reader identifies the tag and the toll amount is deducted from a linked prepaid wallet or bank account. The system reduces cash handling, vehicle queues and manual intervention.
Earlier, the FASTag ecosystem followed a relatively rigid model. If a user wanted to change the issuer bank, the existing FASTag generally had to be closed and a new tag obtained. This created several practical problems:
- The physical sticker had to be removed and replaced.
- The new tag required fresh issuance and delivery.
- The user had to complete another onboarding process.
- The old wallet had to be closed and its balance reconciled.
- There was a risk of delays, duplicate tags and confusion over the active tag.
- Repeated production and dispatch generated avoidable costs and material waste.
OneTag changes this model by separating the physical tag from the issuer relationship. Much like mobile number portability allows a user to change telecom operators without changing the mobile number, FASTag portability allows the vehicle owner to change the issuer bank while retaining the existing tag.
The Rajmargyatra app functions as the user-facing platform. A vehicle owner enters the vehicle registration number to check eligibility. The current issuer bank sends a six-digit Mobile Verification Code for authentication. After authorisation, the user selects a new participating issuer, completes customer verification and undergoes wallet onboarding with the new issuer. Once the process is completed, the same FASTag continues to operate under the new issuer.
The previous issuer closes the existing wallet and refunds the available balance after applicable adjustments. A cooling period of six months applies before the FASTag can be ported again.
Why portability matters
Strengthening consumer choice
A digital ecosystem becomes truly user-friendly only when consumers can exit as easily as they enter. Before OneTag, FASTag users were often locked into a particular issuer because switching involved physical replacement and administrative inconvenience. This weakened the bargaining power of consumers.
Portability changes that equation. Users may now consider:

A digital ecosystem becomes truly user-friendly only when consumers can exit as easily as they enter. Before OneTag, FASTag users were often locked into a particular issuer because switching involved physical replacement and administrative inconvenience. This weakened the bargaining power of consumers.
Portability changes that equation. Users may now consider:
- Better customer service.
- Faster resolution of failed or disputed transactions.
- Lower fees or more attractive wallet features.
- Better mobile applications and notifications.
- Greater reliability in refunds and grievance handling.
- Integration with banking and vehicle-management services.
The reform therefore introduces a competitive pressure that can improve issuer performance. Banks and other participating institutions will have stronger incentives to retain customers through service quality rather than through procedural friction.
This is a central principle of consumer-centric regulation: the ability to switch providers is itself a form of protection. Even if a user never ports the tag, the availability of portability can encourage issuers to behave more responsibly.
Encouraging competition among issuers
Interoperability enables transactions across different banks, but portability creates competition for the customer relationship. The distinction is important.
A toll plaza may accept a FASTag issued by one bank even when the vehicle crosses a network operated by another entity. That is interoperability. But if the user cannot easily shift from one issuer to another, the market may remain fragmented and service quality may vary widely.
OneTag can deepen competition in three ways:

A toll plaza may accept a FASTag issued by one bank even when the vehicle crosses a network operated by another entity. That is interoperability. But if the user cannot easily shift from one issuer to another, the market may remain fragmented and service quality may vary widely.
OneTag can deepen competition in three ways:
- It reduces the cost of switching.
- It makes issuer-level service quality more visible.
- It allows better-performing banks to attract customers from weaker providers.
Over time, this could push issuers to improve digital interfaces, transaction transparency, wallet management, complaint resolution and refund timelines. It may also encourage innovation in bundled services, such as fuel payments, parking, insurance, vehicle maintenance and travel management.
However, the benefits will depend on the number of participating issuers and the simplicity of the process. Portability is meaningful only when users have genuine alternatives.
Reducing operational costs
The Ministry has highlighted the benefits of OneTag for FASTag lifecycle management. Repeated production, dispatch and reissuance of physical tags generate costs for issuers and inconvenience for users.
A physical tag includes the RFID chip, antenna, adhesive layer, packaging and distribution arrangements. When a user changes the issuer, replacing a perfectly functional tag is economically inefficient. OneTag allows the existing device to remain in use, thereby reducing:

A physical tag includes the RFID chip, antenna, adhesive layer, packaging and distribution arrangements. When a user changes the issuer, replacing a perfectly functional tag is economically inefficient. OneTag allows the existing device to remain in use, thereby reducing:
- Tag manufacturing.
- Packaging and courier expenses.
- Customer support interventions.
- Replacement-related paperwork.
- Inventory and logistics burdens.
- Unnecessary disposal of usable tags.
The savings may be small per transaction, but at the scale of millions of vehicles they can become substantial. The reform reflects a broader policy objective: digital systems should reduce not only transaction time but also the physical and administrative costs associated with digital services.
Supporting sustainability
The environmental argument for OneTag is equally significant. A FASTag is a small object, but mass replacement creates a large cumulative material footprint. Unnecessary replacement adds to plastic, electronic and packaging waste.
By extending the operational life of the existing tag, portability contributes to:

By extending the operational life of the existing tag, portability contributes to:
- Resource conservation.
- Reduced electronic waste.
- Lower packaging consumption.
- Lower transport-related emissions.
- Better alignment with circular-economy principles.
OneTag should not be presented as a comprehensive environmental solution. Its direct ecological impact will depend on actual adoption, the durability of tags and the systems used for recycling defective devices. Nevertheless, it offers an example of how administrative reform and sustainability can reinforce each other.
Governance and institutional significance
OneTag represents cooperation among several layers of the tolling ecosystem. The Indian Highways Management Company Limited, promoted by NHAI, and NPCI are central to the initiative. NPCI provides the technology framework, facilitates portability and updates issuer information within the NETC system, while toll acquirers and toll plazas continue processing transactions through the existing framework.
This institutional arrangement highlights the importance of a common digital infrastructure. A portability system cannot function through isolated bank-level applications. It requires:

This institutional arrangement highlights the importance of a common digital infrastructure. A portability system cannot function through isolated bank-level applications. It requires:
- A central record of the tag and vehicle relationship.
- Secure authentication of the existing user.
- Coordination between the outgoing and incoming issuers.
- Updating of issuer details across the NETC ecosystem.
- Settlement and reconciliation mechanisms.
- Handling of pending transactions and refunds.
- Clear responsibility in cases of failure or fraud.
The success of OneTag will therefore depend on back-end coordination as much as on the Rajmargyatra interface. A simple front-end experience must be supported by reliable data synchronisation and clear service-level obligations.
The initiative also strengthens the role of the Rajmargyatra app as a unified highway-services platform. In addition to OneTag, the app hosts services such as the FASTag Annual Pass, Local Pass and the 1033 emergency helpline. This suggests a gradual shift from fragmented highway services towards a single digital interface for users.
The user journey
The portability process is designed to be completed through the Rajmargyatra app.
Step one: Eligibility check
The user logs in to the app and enters the vehicle registration number. The system checks whether the FASTag is eligible for portability.
This stage is important because not every tag may be immediately transferable. Eligibility could depend on factors such as account status, verification, pending transactions, vehicle-tag linkage and participation of the existing and new issuers.
Step two: Authentication
The current issuer bank sends a six-digit Mobile Verification Code. This ensures that the person seeking portability has access to the registered mobile number and authorises the movement of the tag relationship.
Authentication protects against unauthorised switching, but it also creates a potential accessibility challenge for users whose mobile numbers are outdated or whose bank records are not synchronised.
Step three: Selection of a new issuer
After authentication, the user chooses a new participating issuer bank. The value of this stage will depend on whether the app displays clear information about available issuers, service conditions, customer support and applicable charges.
Consumer choice is meaningful only when users can compare alternatives in a transparent manner.
Step four: Customer verification and wallet onboarding
The new issuer conducts customer verification and creates or activates the new wallet. This stage maintains the regulatory safeguards associated with financial accounts and prepaid instruments.
The process should be designed to prevent unnecessary duplication of documentation. If the user has already completed appropriate verification, repeated requirements should be proportionate and digitally enabled.
Step five: Closure and refund
Once portability succeeds, the old issuer closes the existing wallet and refunds the available balance after applicable adjustments. The outgoing issuer must also deal with pending transactions and other related matters.
This is a crucial stage because disputes may arise over transactions made shortly before the switch. Users must receive a clear statement showing:

- The closing balance.
- Pending toll deductions.
- Adjustments or charges.
- The refund amount.
- The expected refund date.
- The status of any disputed transaction.
Step six: Continued use
The existing tag, Tag ID and vehicle registration number remain unchanged. The user can therefore continue using the same physical tag with the new issuer.
This continuity is the principal benefit of OneTag. It removes the need to access the windscreen, remove an adhesive sticker and wait for a replacement.
Concerns and limitations
The six-month cooling period
A six-month cooling period is intended to prevent frequent switching and administrative instability. It may help issuers manage reconciliation and discourage misuse of portability.
However, it may also constrain users who experience persistent service failures soon after switching. A balanced framework should include exceptions for:

- Closure or merger of an issuer.
- Serious service disruption.
- Repeated unauthorised deductions.
- Regulatory action against an issuer.
- Inability of the issuer to provide essential services.
- Technical failure that prevents toll payments.
The cooling period should not become a mechanism that traps consumers in a poor-quality service relationship.
Refund and pending-transaction disputes
The transfer of the tag does not automatically eliminate financial disputes. Toll deductions may be delayed, reversed or disputed. The previous issuer’s responsibility for the wallet and pending transactions must be communicated clearly.
A user-friendly system should provide a unified transaction history before, during and after portability. Without such continuity, users may struggle to identify whether an amount was deducted by the old issuer, the new issuer or the toll operator.
Data accuracy
OneTag relies on the correct linkage of:

- FASTag ID.
- Registered mobile number.
- Current issuer.
- Customer identity.
- Wallet status.
Errors in vehicle registration details or duplicate tag records could produce failed portability attempts. NHAI has also emphasised the importance of validating vehicle registration numbers for accurate toll collection.
Data accuracy must therefore be treated as an ongoing governance responsibility. Users should have accessible mechanisms to correct errors and resolve mismatches between vehicle records and issuer databases.
Cybersecurity and privacy
The portability process involves sensitive information, including vehicle registration data, mobile numbers, wallet details and transaction records. Any weakness could enable account takeover, fraudulent switching or unauthorised access to balances.
The system should incorporate:

- Alerts for every portability request.
- A short cancellation window before final transfer, where feasible.
- Fraud monitoring for unusual activity.
- Minimal data collection.
- Clear retention and deletion policies.
- Quick restoration procedures in case of unauthorised portability.
Users must also be warned against sharing the verification code with callers claiming to represent a bank or toll authority. Digital convenience must not come at the cost of weaker security.
Digital exclusion
The Rajmargyatra app-based design is convenient for smartphone users, but not all vehicle owners have equal digital access. Some may face difficulties because of:
Digital exclusion
The Rajmargyatra app-based design is convenient for smartphone users, but not all vehicle owners have equal digital access. Some may face difficulties because of:
- Limited internet connectivity.
- Low digital literacy.
- Language barriers.
- Inaccessible app design.
- Mobile numbers not linked to the issuer.
- Difficulty completing digital verification.
The system should therefore be supported by multilingual interfaces, accessible customer care, assisted service points and a reliable helpline. A digital-first service should not become a digital-only service.
Issuer participation
Portability will be effective only if a sufficiently large number of issuers participate and comply with common standards. If only a limited set of banks is available, users may still have little practical choice.
Regulators and system operators should publish information on participating issuers, service standards, grievance channels and portability success rates. Transparency can prevent the facility from becoming merely symbolic.
OneTag and the future of tolling
OneTag should be viewed as part of a larger transition in highway management. The government’s stated objective is to move towards barrier-free tolling with zero stoppage and zero waiting time by using artificial intelligence and automatic number-plate recognition.
FASTag is an important intermediate stage in this transition. It enables automated payment, but vehicles may still encounter queues because of toll-plaza design, insufficient lanes, low balances, damaged tags, disputed transactions or enforcement procedures.
The next generation of tolling may combine:

- Satellite or distance-based tolling.
- Real-time vehicle and payment databases.
- Dynamic traffic management.
- Digital enforcement and dispute resolution.
- Predictive maintenance of toll infrastructure.
In such a system, portability becomes even more important. Users should not be tied to a particular issuer merely because a physical device was installed on the vehicle. The identity of the vehicle and the payment relationship must be managed through interoperable digital architecture.
At the same time, the expansion of automated tolling raises questions about surveillance, consent, data retention and accountability. Greater efficiency must be balanced with safeguards against excessive collection and misuse of mobility data.
Policy recommendations
To maximise the benefits of OneTag, the following measures are desirable:

Policy recommendations
To maximise the benefits of OneTag, the following measures are desirable:
- Publish clear eligibility rules: Users should know why a tag is eligible or ineligible and what steps are required to resolve a problem.
- Guarantee time-bound refunds: The system should specify the maximum time for refund of the previous wallet balance.
- Create a unified grievance mechanism: Users should not be forced to separately approach NHAI, the old issuer, the new issuer and the toll plaza for one unresolved transaction.
- Provide portability exceptions: Genuine service failures and issuer-related disruptions should permit switching before the six-month cooling period ends.
- Strengthen cybersecurity: Every portability event should generate alerts, audit trails and mechanisms for reporting unauthorised transfers.
- Ensure multilingual access: The Rajmargyatra app and support services should function in major Indian languages.
- Display issuer performance indicators: Complaint resolution time, refund performance and transaction reliability could help consumers make informed choices.
- Integrate accessibility features: The service should be usable by senior citizens and persons with disabilities.
- Measure environmental gains: NHAI and issuers should track the reduction in replacement tags, packaging and disposal.
- Maintain independent oversight: Portability data should be periodically audited for failures, fraud, exclusion and unfair issuer practices.
Conclusion
OneTag is a practical reform with wider institutional significance. By allowing users to change their FASTag issuer without replacing the physical tag, it converts interoperability into meaningful consumer portability. It can reduce switching costs, improve competition among issuer banks, lower operational expenses and limit the unnecessary production of replacement tags.
Its success, however, will depend on implementation. Transparent eligibility, timely refunds, strong cybersecurity, accurate vehicle records, effective grievance redressal and inclusive access are essential. The six-month cooling period must be applied carefully so that it prevents misuse without trapping users with failing service providers.
For India’s highway economy, the broader lesson is clear: digital transformation should not merely shift an existing procedure onto an app. It should redesign the relationship between the citizen, the service provider and the public infrastructure. OneTag does this by ensuring that the vehicle-linked digital identity remains stable while the service provider becomes replaceable.
In that sense, OneTag is more than a convenience feature. It is a step towards a competitive, citizen-centric and resource-efficient digital tolling ecosystem—one that can support India’s longer-term ambition of seamless, barrier-free mobility.
