How do you acquire a 4B Card?

The first point of call to get a MasterCard or Visa Card via 4B would be to locate a local bank which is part of the Sistema 4B. You can then begin the process of getting a 4B Card, which will require a credit check being carried out in your name. If you are approved for a 4B Card, you can expect to have the card in your procession within several working days. As soon as the card has been activated, you can start using it to play all your favourite games at any online casino which accepts MasterCard or Visa as a form of payment.

Making deposits with a 4B card

When you are sure that your casino of choice supports MasterCard and Visa as payment (most do), you can then make deposits with your 4B Card. Simply log on to your casino account, head to the payments page and enter the amount of money you would like to deposit into your casino account. Your card will then get immediately billed for the transaction.

What are the benefits of using 4B?

This payment system is extremely convenient to use. It is also instant, meaning players can have instant access to their funds and start playing their favourite games straight away.

Another advantage of the 4B system is the fact it is widely used and available across Europe, meaning finding a casino site that accepts it should not be a problem.
