A voucher is a form of bond worth a specific monetary value that can be used as unit of exchange for certain goods, services, or in specific circumstances. Examples include lunch vouchers, gift vouchers and discount vouchers.
Some community currencies, like the Bristol and Brixton Pounds are legally referred to as vouchers, in order to not contravene legislation against printing money. In the terminology of the Bank of England, the Transition Currencies are local vouchers and not money. 1
