In 1991, MasterCard introduced a brand of debit and prepaid cards called Maestro. The debit cards are obtained from banks associated with the company and linked to your bank account, but the prepaid option doesn’t require having a bank account at all.
You can use your Maestro cards to pay for a variety of different things online, including a wide range of goods and services, and at online casinos. In fact, you’ll struggle to find a site that doesn’t allow you to use it.
