Paysafecard is a prepaid voucher. You buy it online through your Paysafecard account or in a shop that sells it, then pay at the casino by entering the 16-digit PIN. As PPRO's summary describes it, you choose Paysafecard at checkout, enter the PIN on a Paysafecard-hosted page and approve the payment, and the United Kingdom is a supported country.
The appeal is control. You can only spend what is on the voucher, and the casino never sees your bank or card details. A my paysafecard account lets you combine codes into one balance and gives higher payment limits.
Paysafecard is built for paying, not for receiving money, so you will usually need a different method, such as a bank account, to withdraw. Check the casino's cashier page before you deposit so you know how any winnings will reach you.
Vouchers carry their own fee rules, including a monthly maintenance fee that a Paysafecard account avoids, so read Paysafecard's terms if you plan to hold a balance.
