Recommended system environment for international payment

Some international participants may experience difficulties when making a payment with an overseas credit card. Based on a successful payment completed by an international participant, we recommend using a Windows PC with the Microsoft Edge web browser when registering and making payment.

If you encounter a payment issue, please try using this recommended environment before contacting the ACUP 2026 Organizing Committee.
