A gift card is a prepaid card that can be used as a form of payment at specific retailers or service providers. It typically has a set monetary value and can be purchased at various locations, including stores and online. Gift cards are popular for special occasions, allowing the recipient to choose their own gifts. These cards often come with terms and conditions, such as expiration dates or restrictions on usage. Many retailers, like Amazon or Starbucks, offer their own branded gift cards, making them a convenient option for gifting. They can also be used to promote customer loyalty and encourage spending.
