| Decision factor | IDFC FIRST Bank Zero Balance BSBDA | AU Small Finance Bank Basic Savings Bank Deposit Account |
|---|---|---|
| Cost / charges | No average monthly balance requirement or non-maintenance charge; reviewed page states common services including IMPS, NEFT, RTGS, ATM transactions, debit card and SMS alerts are free. | No average monthly balance requirement; reviewed BSBDA schedule lists debit-card annual fees and several core services within the free-service set, while replacement/other charges can still apply. |

These tools help narrow or inspect the records. They do not replace bank eligibility, live pricing or account-specific controls.
One side's source depth or freshness never fills a gap in the other record.
