"Vouchers are paper, token or e-vouchers that can be exchanged for a set quantity or value of goods, denominated either as a cash value (e.g. USD 15) or predetermined commodities or services (e.g. 5 kilos of maize; milling of 5 kilos of maize), or a combination of value and commodities. They are redeemable with preselected vendors or in ‘fairs’ created by the agency. Vouchers are used to provide access to a range of goods or services, at recognised retail outlets or service centres. Vouchers are by default a restricted form of transfer, although there are wide variations in the degree of restriction/flexibility different voucher-based programmes may provide. The terms vouchers, stamps, or coupons are often used interchangeably (CaLP 2017)."
