Can I pay with a credit card? When you wish to register for and attend a conference, the first step is login to system and choose what you wish to register for, see our article on registering for the conference. Depending on the conference, they may or may not allow payment by credit card. If they do, you will see the option on the Checkout step, see the image below and paying for my registration. If do not see the option and you still wish to pay by credit card, you need to contact the conference organisers to organise a payment method.
