For many years, financial verification in India depended on manual, document-based processes. Borrowers were asked to submit printed bank statements, scanned PDFs, salary slips, ITR files, or photocopies to apply for loans, credit cards, insurance policies, or wealth products. While this system was widely accepted, it introduced major risks such as data leaks, fraud, delays, and loss of control over personal information. The Account Aggregator (AA) framework, introduced and regulated by the Reserve Bank of India, replaces document uploads with secure, consent-based data sharing. Instead of forwarding PDFs or physical files, users can digitally authorize verified data to be fetched directly from banks, insurers, mutual fund companies, government systems, and other financial institutions. This article explains the key differences between traditional document sharing and the Account Aggregator framework, and why AA is expected to become India’s default standard for financial data exchange.
The Traditional Way of Sharing Financial Documents
Until recently, most financial applications in India required applicants to share documents in one of the following ways:
- Downloading bank statements and sending them over email
- Scanning or photocopying physical documents and submitting them to agents or branches
- Forwarding PDFs through WhatsApp or unsecured cloud links
- Sending passbook snapshots or salary slips to loan executives
Although common, this process introduced problems:
- Forgery and manipulation: PDFs and image-based files can be edited before submission.
- Data leakage: Document sharing through email or messaging apps exposes sensitive information.
- Lack of control: Once a user shares a file, there is no way to track who accessed or stored it.
- Slow processing: Lenders spend days manually verifying documents, leading to delays and repeated follow-ups.
What Is the Account Aggregator (AA) Framework?
The Account Aggregator system allows users to share their financial information digitally through secure, encrypted, consent-driven data flows. Instead of uploading documents, the user gives approval for the data to be fetched directly from the source institution (such as a bank) and shared with a requesting entity (such as a lender).
Account Aggregators are licensed as NBFC-AA (Non-Banking Financial Company – Account Aggregator) under RBI regulations. They do not store or sell data. Their only function is to act as consent managers that securely transfer financial information between institutions.
Key entities in the AA ecosystem:
| Entity | Role |
|---|---|
| FIP (Financial Information Provider) | Bank, NBFC, Mutual Fund, GSTN, Insurance Company etc. that holds financial data |
| FIU (Financial Information User) | Entity requesting access to data, such as lenders, wealth managers, insurers, fintech platforms |
| AA (Account Aggregator) | Consent-based, encrypted data transfer layer |
| Customer | Individual or business that owns the data and controls consent |
How Account Aggregator Works (Step-by-Step Flow)
- User applies for a financial service (loan, investment, insurance, etc.).
- The requesting platform sends a data access request through an AA.
- The user approves or rejects the request through an AA app or interface.
- The AA fetches the required data from the financial institution via secure APIs.
- Data is encrypted and passed to the requesting institution in real time.
- The user can track, revoke, or limit consent at any time.
No PDFs, no photocopies, no email forwarding – only secure, real-time, user-controlled access.
Why Account Aggregator Is Safer ?
| Factor | Traditional Document Sharing | Account Aggregator (AA) |
|---|---|---|
| Data Source | User-submitted files | Fetched directly from banks and institutions |
| Fraud/Editing Risk | High | Zero (tamper-proof) |
| User Control | Lost after sharing | Full control and revocation |
| Encryption | Not guaranteed | Mandatory end-to-end encryption |
| Traceability | No tracking | Digital consent log available |
| Regulation | Unregulated process | RBI-licensed and audited |
Adoption of Account Aggregator in India
The AA network is now live with most major Indian banks and lenders. Examples:
- Banks live as FIPs: SBI, HDFC Bank, ICICI Bank, Axis Bank, Kotak, IDFC First, IndusInd, Federal Bank
- Lenders using AA as FIUs: Bajaj Finserv, Tata Capital, Navi, KreditBee, Lendingkart, Capital Float, etc.
- Upcoming integrations: GSTN, insurance companies, pension systems, income tax AIS data
The ecosystem is coordinated by Sahamati, the industry alliance enabling AA adoption across BFSI players.
Use Cases of Account Aggregator Beyond Lending
| Sector | Example Use Case |
|---|---|
| Retail Lending | Instant bank statement checks for personal, home, or credit card loans |
| SME Lending | Combined banking + GST data for faster working capital approvals |
| Wealth Management | Portfolio aggregation across mutual funds, insurers, deposits |
| Insurance | Income and risk-based underwriting without physical documents |
| Personal Finance Apps | Unified money dashboard without manual uploads |
| Tax Filing | Auto-fetch interest, MF, and account data instead of uploading PDFs |
Comparison: Account Aggregator vs Traditional Document Sharing
| Criteria | Traditional Sharing | Account Aggregator |
|---|---|---|
| Verification Time | 2–10 days | Seconds to minutes |
| Data Authenticity | User-provided, may be tampered | Direct from financial institution |
| Operational Effort | Manual, repetitive uploads | One-time, reusable consent |
| Security Level | Depends on sender | Encrypted, regulated |
| Customer Experience | Paperwork-heavy | Digitally driven |
| Regulatory Oversight | None | RBI governed |
| Scalability | Limited | API-driven and automated |
| Risk of Data Misuse | High | Low, with auditable consent logs |
Real-World Scenarios of Account Aggregator
Retail borrower: A personal loan that used to take a week for verification can now be approved in under 24 hours when bank data is fetched through AA.
Small business: Instead of collecting GST files, bank statements, and financial reports manually, an SME can share all data in a single digital consent flow, reducing approval times from weeks to days.
Wealth platforms: Instead of manually entering investment records, users can grant one-time consent for real-time portfolio visibility.
Current Challenges and Limitations of Account Aggregator
- Low awareness among consumers and small businesses
- Not all banks and NBFCs are fully live as data users
- Digital literacy gaps in rural areas
- Some institutions still rely on paper-based underwriting
- Borrowers sometimes perceive physical documents as “safer”
The Future of Account Aggregator in India
The Account Aggregator network is part of India’s Digital Public Infrastructure (DPI) stack, alongside Aadhaar, UPI, DigiLocker, ONDC, and OCEN. Over time, AA is expected to power:
- Automated credit scoring for millions of thin-file borrowers
- OCEN-enabled embedded lending inside apps
- AI-based underwriting using verified cashflow data
- Pension, tax, and insurance data interoperability
Just as UPI transformed payments, AA is expected to become the default financial data-sharing layer across India.
Why Traditional Document Sharing Still Exists ?
Despite its flaws, traditional sharing is still common. Some reasons include:
- Lack of awareness among borrowers about AAs and how they work.
- Incomplete adoption by smaller lenders or rural banks that are yet to integrate with the AA ecosystem.
- Habit and trust. Many borrowers still believe handing over physical papers is “safer” than digital consent, even though evidence suggests the opposite.
This coexistence is temporary. Just as UPI gradually replaced cash-based payments for small transactions, AAs are expected to replace document-heavy processes for credit and financial services.
FAQs – Account Aggregator vs Traditional Document Sharing
-
Why is traditional document sharing considered unsafe?
Traditional sharing often involves physical copies or emailed PDFs. These can be tampered with, misplaced, or accessed by unauthorized people. Borrowers also lose control once the documents leave their hands.
-
Does Account Aggregator store my data?
AAs do not store your data. They only transfer it securely between financial institutions with your consent. All transfers are encrypted, and the process is regulated by the RBI.
-
Can lenders still ask for physical documents even if I use an AA?
Yes, some lenders may still request physical documents if they are not fully integrated with the AA ecosystem. However, more and more institutions are adopting AAs because they save time and reduce fraud risks.
-
Is the AA system only for loans?
No. AAs can be used for various financial services, including wealth management, insurance, and even tax-related processes. Any service that requires secure financial data can benefit.
-
Do I need to pay to use an AA?
No. Customers do not pay to use the AA system. The costs are borne by financial institutions that integrate with AAs.
-
Can I revoke consent from AA after sharing my data?
Yes. Consent is always in your control. You can revoke or modify access at any time through the AA platform.
-
Who regulates the Account Aggregator ecosystem?
The Reserve Bank of India (RBI) regulates AA entities under the NBFC-AA license framework.
-
Can fraud still happen with AA?
Risk is dramatically lower because data is fetched directly from verified sources.
-
Can AA be used without a smartphone?
Yes, if the platform provides web-based consent flow. A mobile device is not mandatory.
-
Are all banks connected to AA?
Most major banks are live. Some regional and cooperative banks are still onboarding.
-
Will AA replace DigiLocker?
No. DigiLocker stores documents. AA transfers real-time financial data. Both will coexist.
Conclusion
Traditional document sharing may feel familiar, but it is slow, insecure, and offers no control once a file leaves the user’s hands. The Account Aggregator framework replaces this model with real-time, consent-based, RBI-regulated data sharing that improves security, transparency, and approval speed for both users and institutions.
As more banks, lenders, insurers, and government systems join the AA network, it is expected to become the default method for financial data exchange in India-much like UPI became the default for payments.
