I can not use my credit card. There is an error

If the error mentions that you can not use the specific credit card, we can not do anything about it. Please explore the accepted forms of payment that are available to EAI users.

In case you do not own a credit card visible in the article, use the wire transfer option with the necessary information in the payment order, i.e. institution name paying, registrant name, conference acronym and paper ID.
