There are two main types of gift cards: store-specific and general-use. Store-Specific Gift Cards: Store-specific gift cards can only be used at the specific retailer or group of retailers associated with that card. General-Use Gift Cards: General-use gift cards function like debit cards and can be used at any store or ATM that accepts Mastercard, VISA, or Maestro. These cards offer more flexibility and can appeal to a broader range of recipients since they can be used almost anywhere.
