I only know 3-4 sites that take Visa for digital currencies, they do it 'under the table', for around 15-20% fees, and for max $250. if it's not through LiqPay then they only allow you to do it after passing a ton of verification.. so much that it deters potential fraud for such little amounts and also drives away most customers.

You do fully realize there are countless carding forums solely dedicated to defrauding so-called 'Fraud proof/scraping gateways' who will now be looking at your service to cash out instead of mass ordering Iphones and fencing them.

There's a guy in Ukraine now who sells this virtual fraud system where you enter cardholder address, at the push of a button it completely changes your IPs, hardware, browser and plugin profile/fingerprint to something random so you can card away Apple.com all day long without worrying about pesky VerO fraud scraping.This is the kind of well organized fraud you will have to go up against and Visa/MC will not help you at all, they'll just cancel your service once too many chargebacks start happening.

The only way to do this safely is to use high risk payment gateways so if something happens after 30 chargebacks in one week you can just switch to a new one without having Visa fux0r up your real merchant account. If it were easy to do this, you'd already see a million Visa 2 Ukash sites but you don't for a good reason

Debit/ATM card is a good idea though. Why no other exchangers doing this I don't know, since most gateways that take live payments through Interac/Poli/iDeal/ect don't allow refunds.
