A Bank Pass Book is a copy of the ledger account maintained by a bank to record the transactions of its clients. It is the copy of the ledger account provided periodically to the customer in order to inform him/her about the transactions and balances in the account. Each customer is issued a separate passbook by the bank. The credit side of the Pass Book shows receipts of the clients; on the other hand, the debit side shows the withdrawals or payments made by the clients.
