The engine preserves that scope conflict instead of converting it into one universal count.AU currently publishes ₹1 lakh/day UPI in its digital transaction limits. Its UPI page states Android users are limited to ₹5,000 or 20 transactions for the first 24 hours; iOS users are limited to ₹5,000 or 20 transactions per 24 hours for the first 72 hours, after which the ordinary ₹1 lakh/day and 20-P2P-transaction structure applies.

UPI LiteCurrent RBI/NPCI framework is ₹1,000 per transaction and ₹5,000 maximum stored balance. A current-dated HDFC PayZapp article still carries older ₹500/₹2,000 copy, which is flagged as stale/conflicting rather than used as the current limit.AU lists UPI Lite as a current feature. The engine uses current RBI/NPCI system limits of ₹1,000 per eligible transaction and ₹5,000 maximum stored balance unless AU publishes a stricter live app limit.
RuPay credit-card UPIHDFC allows eligible RuPay credit cards to be linked on UPI for merchant/e-commerce payment flows. HDFC currently states up to ₹1 lakh/day (₹2 lakh for certain special MCCs) subject to available card limit, with ₹5,000/day for the first 24 hours after linking; NPCI’s issuer/risk/customer-limit rule remains controlling if lower.Eligible RuPay-credit-card UPI is kept separate from AU account-funded UPI and follows NPCI merchant-only/issuer-risk/card/customer limit controls rather than automatically inheriting the AU deposit-account daily cap.
AutoPay / mandatesUPI AutoPay is treated separately from one-off UPI payments; NPCI mandate controls include modify/revoke/pause/unpause and pre-debit notification rules.AU lists UPI Mandate and UPI Circle. Mandates are recurring/authorized payment instructions; UPI Circle is delegated access and is not treated as account ownership by the secondary user.
Failure / recoveryUPI PIN can be reset through the bank app; device/SIM/mobile changes trigger temporary cooling. Incoming P2P limits and outgoing send limits are kept separate because HDFC publishes distinct controls.Registered-mobile/device and account verification govern access; current bank support/live app controls should be used after device changes, failed registration or disputed transactions.
Wrong-fit risks

Keep each product’s cautions beside the product.

A useful comparison shows what can make either option unsuitable instead of averaging those conditions into a score.

HDFC Bank

HDFC Bank UPI — HDFC Bank App

  • New users or users changing device, SIM or mobile number are currently limited to ₹5,000 for the first 24 hours on Android and 72 hours on iOS.
  • HDFC first-party pages disagree on transaction count scope: the App FAQ says 10 Send Money/P2P transactions while the general limit page says 20 P2P/P2M transactions. Both are retained with their scope.
  • A HDFC PayZapp article still displays older ₹500/₹2,000 UPI Lite figures; the current RBI/NPCI framework is ₹1,000 per transaction and ₹5,000 stored balance, so the stale article is not treated as controlling.
AU Small Finance Bank

AU Small Finance Bank UPI — AU 0101

  • Android and iOS have different first-registration cooling periods: 24 hours versus 72 hours under AU’s current page.
  • AU separately publishes incoming UPI P2P controls—up to ₹4 lakh received in 24 hours with transaction-count conditions—so incoming credit limits should not be mistaken for the ₹1 lakh outgoing debit limit.
  • The ₹50,000 first-three-hours new-payee restriction on AU’s general digital-transfer page is a beneficiary control for bank transfers; the UPI page’s own first-registration cooling rules are used for UPI.
