A specific type of check which includes a segment
(known as the voucher) which details the reason or purpose for the check. The voucher
would include explanations of the payment
, such as "Payment for advertisement running April 1 - April 30" or "$300 for agreed upon fee, $50 for late payment". The person
who receives the check detaches the voucher before cashing
or depositing the check, and will often keep the voucher for their records.
