银行存折，或存款簿，粤语区俗称红簿仔，**地区邮局称为储金簿，是用来记录存款户口的银行交易的簿子。其面积大小会因不同多家以及银行机构而不同，可以像支票簿般大小，或护照的大小。

一般情况，银行存折是用于少数量交易的户口，例如活期存款。在早期的银行里面，银行柜员会用手写下交易的日期和款项，最新的存款结余，并签下他们的记号或印章。现在客户则可透过自动柜员机，自助打印机（类似自动柜员机），或直接到银行分行利用小型点阵打印机或喷墨打印机来更新银行存折。

有些供应商，例如TallyGenicom，提供了专门用来打印存折的存折打印机。这类打印机改善了柜员机的生产率，提供更快的交易时间，更多的自动功能。

A passbook or bankbook is a paper book used to record bank transactions on a deposit account. Depending on the country or the financial institution, it can be of the dimensions of a chequebook or a passport.

Traditionally, a passbook is used for accounts with a low transaction volume, such as a savings account. A bank teller or postmaster would write, by hand, the date and amount of the transaction, the updated balance, and enter his or her initials. In the late 20th century, small dot matrix or inkjet printers were introduced capable of updating the passbook at the account holder's convenience, either at an automated teller machine or a passbook printer, either in a self-serve mode, by post, or in a branch.
