BD meaning in Accounts and Finance ?

A cheque, or check (American English; see spelling differences), is a document that orders a bank to pay a specific amount of money from a person's account to the person in whose name the cheque has been issued. The person writing the cheque, known as the drawer, has a transaction banking account (often called a current, cheque, chequing or checking account) where the money is held. The drawer writes the various details including the monetary amount, date, and a payee on the cheque, and signs it, ordering their bank, known as the drawee, to pay that person or company the amount of money stated.

Definition of a cheque as per The National Provincial Bank circa 1968 was "an unconditional order in writing drawn on a Banker, signed by the drawer, instructing the Banker to pay on demand a sum certain in money to or to the order of a specified person or to Bearer and which does not order any act to be done in addition to the payment of money".

Although forms of cheques have been in use since ancient times and at least since the 9th century, it was during the 20th century that cheques became a highly popular non-cash method for making payments and the usage of cheques peaked. By the second half of the 20th century, as cheque processing became automated, billions of cheques were issued annually; these volumes peaked in or around the early 1990s. Since then cheque usage has fallen, being partly replaced by electronic payment systems. In an increasing number of countries cheques have either become a marginal payment system or have been completely phased out.
