| Decision factor | AU Small Finance Bank Digital Savings Account | IDFC FIRST Bank Quantum+ Savings Account |
|---|---|---|
| Cost / charges | No minimum-balance requirement under the reviewed product page; debit-card and other transaction charges follow the applicable AU Service Fee Reckoner. | No minimum average balance. The Quantum+ debit card is issued without charge in the first year; from the second year the prevailing debit-card annual fee applies. An opening funding request may appear but is not a fee or ongoing balance requirement. |
| Balance / relationship | No minimum balance. | Zero AMB. Any initial funding requested during onboarding remains the customer’s usable account balance after successful opening. |
| Core benefits | Monthly interest payouts, digital/video onboarding, unlimited online RTGS/NEFT/UPI/intra-bank transfers and a RuPay Platinum Debit Card proposition. | Monthly savings-interest credits, completely digital app onboarding, Quantum+ Visa Classic debit card, and an optional FD-backed lifetime-free Quantum+ credit-card proposition under separate terms. |
| Limits / allowances | Debit-card and transaction limits follow the issued AU card and current service-fee schedule. | Quantum+ Visa Classic debit-card relationship currently lists ₹1 lakh daily ATM withdrawal and ₹2 lakh daily POS/e-commerce purchase limits. Digital opening is app-only and cannot be completed at a branch. |
| Eligibility | Indian citizen age 18+ with required government KYC documents. | Eligible resident individuals age 18+ with PAN, Aadhaar and Aadhaar-linked mobile. Customers who currently hold or previously held an IDFC FIRST Savings Account or Fixed Deposit are not eligible for Quantum+ under the reviewed FAQ. |
| Ongoing relationship rule | Standalone digital AU savings relationship. | New-to-bank digital savings proposition; exact card and optional FD-backed-credit relationship terms remain product-specific. |

One side's source depth or freshness never fills a gap in the other record.
