If a merchant’s QR code will not scan, ask for the merchant’s UPI ID (VPA), enter it in a trusted UPI app’s Send or Pay flow, verify the resolved payee name and amount, and then approve with your UPI PIN. If the app itself is failing, try another UPI app already linked to the same bank account, use an available checkout option such as “Pay by any UPI app,” or choose a supported fallback such as pre-enabled UPI Lite, NFC Tap & Pay, *99# or UPI 123Pay. First check whether the original transaction is pending or debited so you do not pay twice.
What to do first
A QR code is only one way for a merchant to accept UPI. NPCI lists merchant QR, intent, app-based and Collect integration modes, and BHIM supports sending money by UPI ID or account number as well as scanning a QR. That means a failed camera scan does not automatically require cash or a card.

- Ask the merchant for the exact UPI ID or VPA used for the business.
- Open a trusted UPI app and choose its Send, Pay or Pay by UPI ID option.
- Enter the ID manually and wait for the app to resolve the recipient name.
- Compare that name and the amount with the merchant’s displayed business details.
- Authorize only after the details are correct, using your UPI PIN inside the payment app.
- Check the transaction result in the app and your bank notification before trying again.
Do not substitute a phone number, an unverified address or a QR image forwarded by an unknown person for the merchant’s confirmed UPI ID. A merchant QR can encode information such as a UPI ID and amount, but manual entry removes the visual check provided by scanning, so the payee verification step matters.

When the QR code will not scan
Try a clean QR and camera permissions
Ask the merchant to display the current QR again, preferably flat, well lit and without glare or damage. Keep the camera far enough away to focus and check that the UPI app has camera permission in the phone’s settings. If the app shows a scan frame, keep all corners of the code inside it for a few seconds rather than moving the phone rapidly.

Switch to the merchant’s UPI ID
If repeated scans fail, stop treating the QR as the only route. Ask the merchant to read or display the business UPI ID and use the app’s manual UPI-ID payment flow. Before entering your PIN, ask the merchant to confirm that the resolved recipient name is the right business and that the amount shown in your app matches the bill.
Use a checkout hand-off when buying online
For a website or app checkout, look for an option labelled “Pay by any UPI app” or similar wording. Select it and choose a supported UPI app already installed on your phone. NPCI’s June 2026 BHIM guidance depicts a merchant checkout offering either a dynamic UPI QR or a UPI ID and says the any-UPI-app option should be prominent on desktop web checkout. The exact button and list of supported apps can vary by merchant and device.
Do not accept an unexpected replacement address
If someone sends a different UPI ID in a phone call or message after you have started paying, pause and verify it with the merchant through a trusted channel. A legitimate-looking name alone is not proof that the account belongs to the shop; confirm both the payee identity and the amount on your own screen.

If the UPI app will not open or complete payment
Identify whether the problem is the app, the phone’s connection, your bank service or the merchant’s acceptance setup. The alternatives below are not interchangeable: each has its own device, merchant and account requirements.
| Route | What you need | What can block it | Amount or status notes |
|---|---|---|---|
| Another UPI app | A second trusted UPI app already installed and configured with the same bank account | The issue may be at the bank, operator or network level, so changing apps may not help | Use the app’s transaction history to verify the result before retrying |
| UPI ID/VPA entry | The merchant’s confirmed UPI ID and a functioning Send or Pay flow | Incorrect address, mismatched payee name or merchant not accepting that ID | Verify recipient and amount before entering the PIN |
| UPI Lite | UPI Lite enabled and prefunded before the problem; a compatible merchant QR | No prior balance, unsupported app or merchant, or a payment above the cited limit | NPCI’s 2024 UPI Lite booklet describes merchant QR payments below ₹200 without a UPI PIN from the Lite balance |
| Tap & Pay | A phone with NFC, an app supporting the feature and a merchant NFC smart tag or compatible acceptance point | NFC disabled or absent, incompatible app, or merchant without NFC acceptance | The phone reads the payee UPI ID/VPA through NFC instead of the camera; availability is not universal |
| *99# | A participating bank and a phone/service able to use the USSD channel | Your bank, mobile operator or account may not support the required menu | Check current bank availability; do not assume every UPI account can use it |
| UPI 123Pay | A participating provider and the supported voice or payment channel | Provider, bank, language, handset or merchant support may be absent | NPCI maintains a live-members list; verify participation before relying on it |
| Other merchant method | The merchant must accept another method and provide its normal instructions | The shop may not support bank transfer, a Collect request or another rail | Ask the merchant to confirm the exact payment address and method first |
Try another configured UPI app
NPCI says a customer can use multiple UPI applications. If a second app is already registered with the same bank account, open it and use the merchant’s UPI ID or a fresh QR. This is useful when one app has a local software problem, but it cannot bypass a bank outage, a mobile-data failure or a merchant-side acceptance problem. Do not install an unfamiliar app in a hurry and enter banking credentials just to complete one purchase.
Use UPI Lite only when it was set up beforehand
UPI Lite is a small-payment balance rather than a universal replacement for a broken app or QR. NPCI’s 2024 product booklet describes paying a merchant by QR for an amount below ₹200 without a UPI PIN, drawing from the Lite balance. The balance must have been enabled and funded before the main payment problem, and the merchant QR and app must support the route. A failed Lite attempt does not make a larger payment eligible.

Try Tap & Pay when both devices support NFC
Tap & Pay uses near-field communication to read the payee’s UPI ID or VPA instead of using the camera. It requires NFC in the customer’s phone, an app that exposes the feature and a merchant NFC smart tag or other compatible acceptance point. Turn on NFC only through the phone’s normal settings and follow the app’s payment prompt. If no NFC prompt appears, the merchant’s tag, your handset or the app may not be compatible; switch to a UPI ID or another method rather than repeatedly tapping.
Consider feature-phone and low-connectivity channels
NPCI identifies *99# USSD and UPI 123Pay voice and payment channels as ways to access UPI beyond a standard smartphone app. Participation is not universal. Check whether your bank and mobile service support the desired channel and whether the merchant can accept the resulting payment flow. UPI 123Pay’s provider list can change, so confirm that your provider is currently listed before depending on it in an emergency.
How to pay safely by entering a UPI ID
- Get the address directly from the merchant. Ask the cashier to display the business UPI ID or provide it from the shop’s established signage or billing system.
- Open the official app you normally use. Start a new Send, Pay or UPI-ID transaction; do not follow a payment link supplied unexpectedly by a caller.
- Enter the complete VPA. Check every character before continuing. A one-character mistake can direct funds to a different account.
- Read the resolved payee. The app should display a recipient name. If it is blank, unexpected or inconsistent with the shop, cancel and ask the merchant to verify the address.
- Enter the exact bill amount. Compare the currency amount on your screen with the merchant’s bill. Be alert to an extra zero or an amount that was changed without explanation.
- Authorize in the app. Enter the UPI PIN only on the trusted payment screen for the transaction you initiated.
- Save the result. Note the success, failure or pending status and the transaction reference. Show the successful confirmation to the merchant if requested, but do not hand over your PIN or allow screen-sharing.
A UPI PIN authorizes a debit; it is not needed to receive money. Anyone asking for your PIN, OTP or remote screen access is asking for information that should remain private, even if they claim to be merchant support or bank support.

Check whether the first attempt is pending before paying again
A frozen screen, spinning indicator or missing merchant notification does not prove that no money moved. Open the app’s transaction history and check the bank’s SMS or other notification. A transaction can be recorded by the bank while the merchant’s screen is still waiting.
If the app says pending
Do not immediately start a second payment. Give the status time to update, retain the transaction reference and ask the merchant to check the receiving side. NPCI says operator issues can delay confirmation and advises contacting your bank if confirmation has not arrived within an hour.
If your account was debited but the merchant has no confirmation
Show the merchant the reference number without exposing your PIN or one-time password. Report the issue through the payment app’s transaction-help feature or your bank’s official support route. Ask the merchant to verify the transaction on their side before attempting another debit. Keep screenshots, the exact time, amount and reference number until the matter is resolved.

If the transaction is marked failed or declined
NPCI’s UPI FAQ describes real-time reversals for declines, but an individual reversal can depend on the bank and transaction status. Check whether the amount has actually returned before making another payment. If a debit is not reversed promptly, contact the bank with the reference number rather than assuming the money is permanently lost or paying again without checking.
Understand the 24/7 statement correctly
NPCI states that UPI payments are available instantly and 24/7 regardless of a bank’s working hours. That describes normal service availability, not a promise that every app, bank, operator, network or merchant system will respond without interruption. A live service can still have a delayed confirmation or an outage.
What the merchant can do
Merchants can keep more than one acceptance route visible: a current QR, the business UPI ID and, where supported, an NFC tag. If the QR is damaged, ask for a newly generated display rather than using a photographed or forwarded code. For online orders, a checkout that clearly offers payment through any installed UPI app gives customers a path when one app cannot launch.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A merchant may offer a Collect request or a bank-transfer address, but do not assume either is available or appropriate. Ask the merchant to state the exact address and confirm the request in your app. You still must verify the payee and amount before authorizing; a Collect request is not automatically safer than entering a UPI ID.
A practical decision path
- Was money possibly sent? Check transaction history and bank alerts first. If the status is pending or the account was debited, follow the resolution steps instead of paying again.
- Is only the QR failing? Request the merchant’s UPI ID, enter it manually and verify the resolved name and amount.
- Is one app failing? Use another trusted app already linked to the account, or select “Pay by any UPI app” at an online checkout.
- Was UPI Lite already enabled? For a supported merchant QR payment below ₹200, the Lite balance may work without a UPI PIN.
- Do both phone and merchant support NFC? Try Tap & Pay; otherwise skip it.
- Do you have a supported feature-phone channel? Check *99# or UPI 123Pay participation with your bank or provider.
- None of these works? Ask for another payment method the merchant genuinely accepts, and verify its details before sending money.
UPI safety checklist for a rushed payment
- Never disclose your UPI PIN, OTP or screen-sharing access to a merchant, caller or supposed support agent.
- Enter the PIN only in the trusted payment app and only for a payment you initiated.
- Confirm the payee name and exact amount on the authorization screen.
- Do not use a replacement UPI ID sent unexpectedly by message or phone without independent merchant verification.
- Remember that receiving money does not require entering your UPI PIN.
- Use the app’s report-issue function or your bank’s official support channel for disputes.
NPCI/BHIM’s safety guidance states: “Please do not share your UPI-PIN with anyone. BHIM does not store or read your UPI-PIN details and your bank’s customer support will never ask for it.” Treat that as a hard rule when a payment is urgent.
What is not guaranteed
Bank participation, app menus, NFC acceptance, UPI Lite availability, feature-phone support and merchant integration can change. The ₹200 figure applies to the merchant-QR UPI Lite condition described in NPCI’s 2024 booklet, not to all UPI payments. Likewise, *99# and UPI 123Pay are listed access channels, not services that every bank or customer can automatically use. When a route is unavailable, return to the verifiable basics: the merchant’s confirmed UPI ID, a trusted app, a visible payee name, the correct amount and a checked transaction status.
