A bank pass book is a copy of the ledger account maintained by a bank to record the transactions of its clients. Each customer is issued a separate passbook by the bank. A bank pass book is the copy of the ledger account that is provided periodically to a customer in order to inform him/her about the transactions and balances in the account. A bank pass book acts as a confirmation about the transactions entered through the bank. Thus, it acts as an evidence for the customer. It includes the date, particulars, cheque number, and amount withdrawn or deposited in the bank account.
