A voucher is a type of document or digital code that acts as a form of payment, offering discounts, credits, or special offers for specific products or services. It serves as a pre-paid amount or a coupon that can be redeemed to reduce the price of a purchase or gain access to special benefits. Vouchers can be used for a wide range of purposes, from travel and accommodations to dining and shopping.

For example, a travel company might provide a voucher for a discount on future bookings, or a restaurant may issue a voucher to offer a free meal on your next visit. Vouchers typically have an expiration date and may come with terms and conditions, such as being valid only on certain dates, or for specific products or services.
