Why am I being charged a credit card processing fee when I register online?

This fee is paid to a third-party that provides these services for Space Foundation and is not considered revenue

Your registration cost includes a non-refundable payment processing fee that enables Space Foundation to minimize registration price increases as much as possible while still delivering a world-class Space Symposium experience. This fee is paid to a third-party that provides these services for Space Foundation and is not considered revenue for Space Foundation, a 501(c)(3) non-profit organization. If you prefer not to pay this transaction fee, you have the choice to pay via ACH. We are pleased to be able to offer this convenience to our customers.
