Determining a transaction fee before an order is processed
- by Kenji Crosland
When users make credit card transactions on my web app, I'd like to include the transaction fee on the confirmation page before the user makes the order. The thing is, there are different transaction fees for different cards. Is there a way to determine a transaction fee from the card number?
I'm using Rails and ActiveMerchant, but I figure this question was applicable to other languages as well.
