What is the ruling on using the IPAY card, which is designed for online purchases, where only a card number is issued, and which involves annual fees and fees for exceeding the loading limit or sending a bounced check?

If the bank takes 100 dirhams in exchange for cashing an invalid check on behalf of the customer, then this is a prohibited usurious loan. However, if the 100 dirhams is a fine for writing an invalid check without cashing it, then a financial penalty is permissible if issued by the Imam or his deputy. Since banking laws are approved by the ruler, it is permissible to use the card if it is free from usurious conditions; otherwise, it is not.
