As a Company we accept payments from customers made via their credit cards. We are charge by the bank for each transaction a fee of 0.67% of the transaction.
1. Can this fee be on charged to the customer?
2. Can a higher fee be on charged to the Customer?
3. On the basis that we do not pass on the on charge to all the customers, to cover the overall credit card fees charged by the bank, can a higher fee be on charged to those that we do in fact charge the fee to?
Thank you & gut Shabbos!
Adding on the charge that you incur from the Credit Card company is permissible, and poses no problem of Ribbis. To charge more than that and have two prices, one for cash and one for credit would be a problem of Ribbis.
