Prepaid card casinos work in a similar way as when using a credit or debit card to bet on your favorite casinos. You then can use various methods, including a credit or debit card, to fund or reload that virtual card. However, there are also virtual prepaid cards (such as Play+), which you can register for on the sites after completing your registration. After adding funds, the account holder typically receives a physical card that usually looks and functions like a credit or debit card. Prepaid cards have to be purchased and loaded with funds before they can be used. Today, prepaid cards are widely used throughout the world and offered by a host of financial institutions. The prepaid card industry traces its roots back to the first gift cards that popped onto the shopping scene back in the 1970s.
