| App / channel | PNB ONE 2.0 and BHIM PNB for smartphone UPI; PNB also offers UPI 123PAY over IVR for eligible feature-phone/no-internet use and card-funded UPI for eligible PNB RuPay credit cards. | Canara ai1Pe is a multi-bank UPI app supporting Canara and other UPI-enabled bank accounts, with UPI Circle, AutoPay, UPI Lite, merchant payments, analytics and QR flows. |
|---|
| Registration | PNB ONE self-onboarding can use debit card, Aadhaar-based view credentials, Internet Banking credentials or branch mode; UPI registration then links eligible account/mobile and establishes UPI PIN. UPI 123PAY provides a separate IVR account/PIN setup route. | Download ai1Pe, verify mobile number by SMS, set app passcode, link the eligible bank account and activate using debit card or Aadhaar OTP before setting the UPI PIN. |
|---|
| Authentication | PNB ONE uses MPIN/biometric for app access and TPIN/OTP for bank transactions, while UPI flows use UPI PIN. PNB's 123PAY IVR can set a UPI PIN using debit-card details, ATM PIN and OTP when required. | Ordinary UPI uses UPI PIN plus device/account controls. Canara UPI Lite permits eligible payments up to ₹1,000 without UPI PIN after Lite enablement; delegated/card-funded flows use their own authorization rules. |
|---|
| Standard limits | No fresh universal PNB account-funded UPI daily ceiling is hard-coded from the 2026 public PNB ONE/UPI pages. The engine retains the older ₹50,000/day figure only as legacy evidence and requires the live PNB ONE/BHIM PNB control for current high-value usage. | P2P: ₹1 lakh per transaction and ₹1 lakh/day, max 20/24h. Verified/special merchant P2M: ₹2 lakh per transaction/day. IPO/Retail Direct: ₹5 lakh per transaction and ₹10 lakh/day. Hospitals/education and tax: ₹5 lakh per transaction/day. QR from gallery: ₹2,000 per transaction / ₹10,000 daily, max 5/day. |
|---|
| Security cooling | No current PNB-specific first-registration/device-change UPI cooling amount is asserted from the reviewed 2026 source set. Live app/risk controls remain controlling. | New UPI user on any enabled app with Canara remitter: Android first 24 hours up to ₹5,000; iOS first 72 hours up to ₹15,000 total, limited to ₹5,000 in each 24-hour cycle. |
|---|
| UPI Lite | PNB's January 2026 results material states PNB ONE 2.0 supports UPI Lite. Current numeric system limits are kept at the RBI/NPCI framework (₹1,000 per transaction, ₹5,000 stored balance) rather than the bank's much older launch-era Lite material. | Current Canara terms: ₹1,000 per UPI Lite transaction, ₹5,000 maximum Lite balance and ₹10,000 cumulative daily spend. Lite is an on-device balance enabled from one eligible linked account and does not require UPI PIN for eligible Lite payments. |
|---|
| RuPay credit-card UPI | PNB's current credit-card portal supports linking eligible PNB RuPay credit cards to listed UPI apps and paying merchant QR/online UPI flows using UPI PIN. The card-funded path is treated as P2M, not as a P2P/receive-funds account substitute. | Canara's current UPI debit table separately lists RuPay credit-card-on-UPI merchant/special-category P2M at ₹2 lakh per transaction and ₹3 lakh/day. Linking uses eligible RuPay card details/OTP and a 6-digit UPI PIN; this card-funded ceiling does not alter P2P account limits. |
|---|
| AutoPay / mandates | PNB ONE 2.0 explicitly supports UPI Mandate. Mandates are stored as recurring authorization rather than being assigned the old PNB ONE generic mobile-banking limit. | Canara explicitly supports UPI Mandate/AutoPay for recurring/future payments and separately documents higher no-additional-factor e-mandate processing for specified merchant categories under current rules. |
|---|
| Failure / recovery | PNB ONE provides UPI transaction history and blocking. PNB's current UPI/123PAY pages publish bank support routes; card-linking issues use the card portal/customer-care path and ordinary payment disputes should follow the relevant UPI/app bank channel. | Device change/Lite disablement has a defined balance-return process in Canara's Lite terms. Account/app support and UPI dispute/reversal processes apply for failed transactions, while re-registration can trigger the documented cooling state. |
