They can't legally charge extra for taking a credit card. That's why many schools don't take them , they have to eat the 2% processing fee charged by the cc company.
Yes, but I think they legally get around it by using a third party vendor in some cases. Example copied and pasted below. Correct me if I'm wrong. Thanks.
"7 - What is the service fee and how much is it?
The service fee is what is charged to the payer when he or she uses a credit card to pay tuition and fees, health insurance premiums, and/or BYU sponsored loans. It is non-refundable. The current service fee charged by the third party vendor is 2.75% of the transaction amount. For example, if the transaction amount is $1705, the service fee would be $46.89 making the total amount due $1751.89.
8 - Is the service fee only applied to tuition related charges? Is insurance included in that?
The service fee is applied to tuition charges as well as related expenses such as class fees, reassessment fees, late fees, and study abroad charges. Health insurance premiums are included in the tuition charge because they are semester/term based.
9 - What is a merchant fee?
Credit card companies charge a fee to the merchant to process a credit card transaction. The merchant is the business that takes your payment. So, every time you use your credit card at BYU, restaurants, over the internet, etc. the business from which you purchase something will be charged a fee by the credit card company. This is generally invisible to the customer."
