In KOMOJU Test mode, you can use the test cards below to simulate successful payments and various errors. The cardholder name and security code (CVV) can be any value, and the expiration date can be any future date. If you want to check the 3D Secure (3DS) authentication flow, please use the dedicated page.
With some connection methods, such as Hosted Fields or the WooCommerce plugin, only 3D Secure (3DS)-enabled test cards are supported, and the cards on this page may not be usable.
If authentication errors persist, please use the cards on the 3D Secure test payment page.
