Final answer:
A pegboard system or check writing system is used to copy details from pegboard checks to the check register, including the date, payee, check number, and amount, maintaining accurate business financial records.
Step-by-step explanation:
The component that is included on pegboard checks, which copies the date, payee, check number, and the amount to the check register is called a check writing system or pegboard system. This system helps businesses keep track of their transactions by ensuring that every time a check is written, the details are recorded simultaneously in their records. The check writing system typically includes a writing board, checks with carbonless copying, and a register for recording transactions. When you write on the original check, the pressure from the writing tool creates an impression on the register below, which is an essential part of bookkeeping for maintaining accurate financial records.
