A voucher is a ticket or printed piece of paper that has a value in money and can be used instead of money to buy or pay for products and services. A voucher is used for different purposes such as sales promotion, giving somebody a gift and thanking customers. Therefore, a voucher has various forms, depending on the purpose of that particular voucher. For example, Central Department store has gift vouchers available for customers who may wish to give these vouchers to somebody else as a gift to be used for buying any products in Central stores. Furthermore, a hotel may give its guests meal vouchers to be used for buying food and drinks in the hotel restaurant.
