: Bangladesh Automated Clearing House (BACH) is a name that has created a stir in the clearing world in Bangladesh. Under this network, clearing is now done centrally at the head office of Bangladesh Bank. This allows customers to withdraw money by clearing their checks through any branch of their bank in one day , which used to take up to a week, especially in the field. In this case, only the image of the check has to be sent , the original check is not required to be sent as before. This system has brought tremendous progress and convenience in banking.
