Is it permissible to deal with a website that provides a US credit card number for a subscription fee and administrative fees ($5 + 5% of the deposited amount), and are these fees considered usury (riba)?

There is no objection to the aforementioned transaction, and the deduction of fees is not considered usury (riba). Rather, these are fees for the services provided. The bank does not provide a loan; rather, it pays the price from the customer's deposited balance and takes a fee for that. This type of card—the debit card—is permissible in Islamic law because it does not generate additional liquidity and does not fall under credit cards.
