Enter the proofing page and register with the correspondent's email address, which will be related to your employment paper. There is information about the certificate on it. If you can prove it, after you submit it online, there is a payment link on the right side of the webpage. You can click and fill in as required. When paper periodicals are printed, IEEE Publishing Society will automatically deduct money from the credit card you fill out. When you submit the final document, if the final document does not lack the required documents, the publishing house will generally not contact you by email, so you should always visit the certification page to pay attention to the status of your paper.
