A savings bank (SB) account is a popular retail deposit account maintained by financial institutions for individual customers who want a secure place to park liquid cash while earning incremental interest income. These accounts facilitate everyday monetary management by allowing users to deposit funds, execute electronic transfers, make purchases via connected debit cards, and withdraw cash through branch counters or automated teller machines. While designed primarily for personal savings rather than heavy commercial transactions, they offer essential financial safety backed by regulatory deposit insurance protections and convenient digital access.
