Voucher

A voucher is a bond which is worth a certain monetary value and which may be redeemed only for specific reasons or on specific goods. Examples include housing, travel, and meal vouchers. Vouchers are a form of scrip. The term voucher is also a synonym for receipt and is often used to refer to receipts used as evidence of, for example, the declaration that a service has been performed or that an expenditure has been made.

The term is also commonly used for labour vouchers and school vouchers, which are somewhat different.
