India’s fraud rules: RBI, NPCI, DoT and UIDAI

RBI’s Authentication Directions have been in force since 1 April 2026, and the revised customer-liability framework applies from 1 January 2027. Six dated rules are mapped here, each with its status and public source, to the controls they call for and the DeepID modules that support them. DeepID supports compliance and never guarantees it.

  1. RBI Authentication Mechanisms for Digital Payment Transactions Directions, 2025

    In force

    RBIIn force 1 Apr 2026

    Every digital payment is authenticated with two distinct factors, one of them created for that transaction. Issuers may add risk-based checks that weigh location, behaviour, device attributes and transaction history. SMS OTP stays a valid factor and newer ones are encouraged.

    Calls for: Beyond SMS OTP, Risk-based checks.

  2. SIM binding: UPI apps today, messaging apps next

    Reported

    DoT and NPCIIssued Nov 2025 · deadline reported as 31 Dec 2026

    App-based messaging services must work only while the registered SIM is present and active in the phone. The compliance date was reported in April 2026 as 31 December 2026. UPI apps already bind to the SIM and the device.

    Calls for: Device and SIM binding.

    Banks are asked to adopt the Reserve Bank Innovation Hub’s mule-detection model, and the I4C Suspect Registry will feed it. An initiative banks are adopting, not a direction.

    Calls for: Mule detection.

  4. Limiting customer liability in unauthorised electronic transactions

    In force

    RBISince Jul 2017

    The burden of proving customer liability lies with the bank. The customer carries zero liability where the bank was at fault, or where a third-party breach is reported within three working days.

    Calls for: Bank liability.

  5. UPI onboarding: device and SIM binding

    In force

    NPCICurrent onboarding requirement

    UPI onboarding binds the app to the device and needs an active SIM linked to the bank account. A new SIM or phone means binding again.

    Calls for: Device and SIM binding.

    What it means for banks

  6. Amendment directions on limiting customer liability in digital transactions

    Applies later

    RBIIssued 24 Jun 2026 · applies 1 Jan 2027

    As reported: zero customer liability where the bank was negligent, and compensation for losses of up to ₹50,000 at 85% or ₹25,000, whichever is lower, once per customer, if reported within five days. RBI issued the directions on 24 June 2026. The terms above are as reported by MediaNama and Business Standard, both secondary; check RBI’s text before relying on them.

    Calls for: Bank liability.

    Proposal

The dates, from September 2025 to March 2027.

Two rules in force, one applying, one deadline reported and one proposal, in the order they fall.

Three figures from public sources. None is a DeepID figure, and none says what DeepID would have caught.

Scams read in the session.

The customer sends the money from their own phone, so only the session shows the pressure. Each pattern links the use case that walks through it.

  • Digital arrest

    Callers posing as police, customs or a regulator keep the customer on a video call and order a transfer to a “safe account”.

    Read in the session: An active call through the payment, a shared screen, payee details typed a few characters at a time.

    Digital arrest, step by step

  • Investment groups

    A messaging group shares “stock tips” and a trading app shows profits that cannot be withdrawn. The customer sends rising amounts to payees that keep changing.

    Read in the session: A run of new payees in days, amounts rising with each transfer, payees receiving from many unrelated senders.

    Investment scams, step by step

  • Scams on older customers

    A caller builds trust over days, then asks for one large payment to someone new while staying on the line.

    Read in the session: A large first payment to a new payee during a long call, with the customer’s agreed support needs on file.

    Vulnerable customers, step by step

Control mapping.

Each control the rule map tracks, whether a rule in India calls for it, and the DeepID modules that support it.

Not mapped yet means no rule is mapped to that control here, not that no rule exists. DeepID supports compliance and never guarantees it, and it claims no regulator approval.

Where the loss falls.

From 1 January 2027, RBI’s amendment directions on customer liability apply. As reported, the customer carries zero liability where the bank was negligent, so the loss can sit with the bank.

Liability, market by market

What India’s banks ask first.

Will a one-hour hold on payments over ₹10,000 become mandatory?

It is a proposal, not a rule. RBI’s April 2026 discussion paper floats a one-hour hold on digital payments of ₹10,000 or more, with trusted payees whitelisted.

A bank that can tell which sessions are at risk can cool off those sessions instead of every payment.

How does SIM binding and re-binding work in a bank’s own app?

UPI onboarding already binds the app to the device and needs an active SIM linked to the account. DeepID binds the bank’s own app the same way: the SIM in the phone is matched to the registered number at sign-up, and the account is bound to that SIM and device.

When the SIM or the phone changes, the customer is bound again after a fresh check, such as a face match, and new payees and higher limits can cool off for a period the bank’s policy sets.

Where does Aadhaar face authentication fit?

With the customer’s consent, a live face can be matched to the Aadhaar record at the moments that need it: a new phone, a UPI PIN reset or a large first payment. UIDAI recorded 28.29 crore face authentications in November 2025.

Liveness and injection checks run on the capture first, so a replayed or generated face is caught before the match.

Is DeepID integrated with MuleHunter.AI?

No integration is claimed. DeepID’s payee and mule signals reach the bank’s FRM beside MuleHunter.AI alerts, and the bank’s team decides on both.

An integration is named on this site only once it is signed.
