Another benefit is that you do not need to provide any additional information to third-party services, whilst FundSend uses the credit card data on behalf of yours. Moreover, you can use FundSend without an actual registration: just put in your credit card details, receive an instant e-card, use it during the game and that is it.
As for the flaws, the main one here is the fact that FundSend is available only to the strict list of countries, and users within any another country cannot use the FundSend service for their needs referring to online payments within casinos.
The second major flaw for such a system is that you cannot use FundSend as an actual e-wallet. You simply bind the credit card of yours to e-card within this system, without an option to top it up separately from your actual card in use. Thus, you can use FundSend for both depositing and withdrawing, yet, you cannot store any currency there: it goes either to your credit card directly, or to the service that you are paying to.
Such service is a good pick for those who dislike the usage of default online casinos and are not willing to disclose their data. In order to play for real money, they can simply create a separate account within the FundSend system and use it on behalf of their actual credit cards for e-commerce as well as online gambling. The major flaw here, of course, is the limitation to the countries that can actually use this service, since if you are not there, it will be required to find any another method. And it is sad that there is no option to register your own e-wallet with FundSend. Yet, still, due to its lack, the service itself is fast and provides you with fair transactions. Along with that, FundSend requires some fees from the transactions done both during deposit and withdrawal stages and, aside from that, there will be an additional charge up to 4 pounds per each transaction. Yet, if you agree with all the terms and conditions, feel free to start the game and choose FundSend as the main payment method.
