A prepaid debit card is a type of payment card that is preloaded with a specific amount of money. Unlike traditional debit cards linked to a bank account, these cards do not require a bank account and can be used for purchases until the balance runs out. They are often used for budgeting, as users can only spend what is loaded onto the card. These cards can be used at most places that accept credit cards, including online retailers. They are popular for gifting, travel, and managing expenses, as they provide a convenient way to carry money without the risk of overspending.
