A gift voucher is a prepaid card or certificate that can be used as a form of payment at a specific store or service. It allows the recipient to choose their own items or experiences, making it a flexible gift option. Gift vouchers often come with a set value and may have an expiration date. These vouchers can be purchased from various retailers, restaurants, or online platforms. They are popular for occasions like birthdays, holidays, and special events, as they provide a convenient way to give a thoughtful gift without the need to select a specific item.
