So you want to give Sega money. This page will hopefully help you on your way.
Update:Unfortunately, Sega of Japan no longer accepts foreign credit cards. As such this guide is.. kind of irrelevant now. Sorry. Err, looks like they do again, at least somewhat. Not all cards will work.
PRE-REQUIREMENT: If you didn’t enter a Japanese name or address when you registered you’re going to need to fake one after logging in. If you registered for the 2nd Alpha tests or earlier you’ll have already done this as it was required. You’ll be prompted to enter said details after you choose your payment method. These details will not impact what payment methods you can use.
First, you’ll need to go to the purchase page which can be found here. ISAO is the company that handles payments for PSO2’s cash shop. You’ll be greeted with the following page.
Enter your username in the first box and password in the 2nd. The 3rd box is a CAPCHA in Hiragana (the screenshot is outdated and shows Katakana). If you can’t read or type Hiragana, you can use this handy tool from Lexilogos to help you. Press the corresponding symbols and copy and paste the result into the box. Press the left button to continue.
A general rule of thumb: The left button is usually always the confirm button.
If you manage to make it past that, you’ll be presented with the following screen.
The only button we’re interested in for now is the first grey button. This will take you to the purchase page. The button below that is your purchase history and the bottom button is to register a credit card (you don’t need to).
Click the first button to be taken to the following screen.
The first set of radio buttons is how much Arks Cash you wish to buy, plus the cost in YEN. The second set of radio buttons is your payment method. This guide will only concern itself with the first payment method for now, which is “Credit Card”.
This is where you enter your card details. Use the drop-down menu at the top to select your card type. The other two fields should be familiar if you’ve used any online payment system, the first is your credit card number and the second is your 3-digit security code (usually on the back of your card).
Use the drop-down menus to select your card’s expiry date (same format as on the card itself). In the field enter the name exactly as it appears on the card itself. The check box is to register your credit card, this isn’t necessary. At the bottom are three buttons, click the top-left of these to continue. It should take you to the next screen if all goes well.
