Any ticket purchase made with an AMEX credit card will incur a 1.1% surcharge. This surcharge is always worn by the ticket buyer and is separate from the standard Humanitix booking fee.
This surcharge cannot be customized or absorbed by the event host.
Buyers are made aware of the AMEX surcharge when entering their credit card information during payment. This is notification sits just above the credit card fields.
The order total will update when the buyer presses place order to complete their purchase, and this charge is recorded on their receipt/invoice.
Due to PCI compliance, we do not have access to payment card information/type until the payment has been processed and so we cannot display the update price during the checkout, which is why we display this notification when card details are entered.
All AMEX users should typically be aware of such surcharges as they are incredibly common.
