As for obvious pros of the FirePay system comparing it to any other similar one, here goes simplicity. All you need for FirePay is your own bank account already opened. If you have such one, feel free to proceed with a further registration of your new online credit card that can be used further during the gameplay.
The next good thing comes from the first one: with FirePay, there is no need to provide actual details of your own bank account or credit card. Instead of it, feel free to use a FirePay e-card for both deposits and withdrawals. And the last but not the least thing, a FirePay e-card can be used with the PayPal service, which means you can handle e-wallets within both services.
The main drawback here is the fact that a minimal fee is required and it is not fixed, depending on the transaction itself and the amount of funds deposited to a card, thus, it is necessary to be careful and double-check the percentage of fees before proceeding in order to make sure that you are totally agree with such conditions. Still, the bright side here is a total transparency: you always see the sum you will be charged with for each transaction done.
To sum up, FirePay is a good choice for those who like such things as debit e-cards systems preferring them to physical credit cards for online payments.
Being available at most countries throughout the world and with PayPal integration, it has rather a user-friendly set of tools for a long and comfortable online gambling session and is supported within the majority of online casinos nowadays.
Being in use for more than 10 years, it has a huge client database, which means it is truly reliable and can be trusted by newcomers who are not sure which method should be used if PayPal itself is not an option for them.
The other bright side is its speed. There are no long forms, and everything can be done in two simple clicks within a neighboring tab, which means everything is done for the sake of gamblers who are not willing to be interrupted during their game.
Aside from that, everything is clear. You get all details about each transaction you have done with FirePay, so there are no hidden operations, and everything can be checked right at once. By the way, if something is unclear, you can always contact FirePay support and check any details with them.
