For sellers located outside the US and UK, we don't have any way to handle direct card-based payments into a card-merchant account balance at your bank. We are looking into payment gateways with broad international support to meet this need, but that's about all we can say about it for now.
Most buyers using PayPal Standard should be offered the option to complete checkout on PayPal's site using a card without requiring a PayPal account; PayPal would only disable that option if they detect the buyer must already have a PayPal account, is using a shared computer, or otherwise potentially risky circumstances they screen for where a card number provided either may not be secure, or may not be legitimate.
