Is it permissible to use a credit card to purchase pre-paid video game cards from suppliers, knowing that their price is paid to the supplier after they are sold?

If the cards represent a financial balance, then purchasing them is considered an exchange (sarf) in which immediate possession (qabd), whether actual or constructive, is required. It is permissible to deduct the price from the credit card if it is directly credited to the seller's account. However, deferring payment of the price is not permissible due to the lack of immediate possession. It is not permissible to profit from this transaction except by selling the card for a different currency.

As for prepaid recharge cards for telecommunications companies, these represent benefits. It is permissible to sell them for more than their value and to defer payment of their price. The ruling on using a credit card to purchase these and other cards depends on the type of card, its terms, and whether it involves usury (riba) or not.
