We're sorry for the trouble with card registration. Based on the official FAQ "I cannot register my credit card" (https://support-evcs.power-x.jp/hc/ja/articles/24904289203097, updated 2026-06-18) and our support guidance, please try the following in order:

1. Update iOS. If you are on iOS 15, credit card registration may fail. Please update to the latest iOS version and try again — this is the most likely cause given your situation.
2. Double-check the card number and security code are entered correctly. Note that prepaid credit cards and debit cards cannot be used.
3. Restart your device and try registering again.
4. When the 3D Secure authentication screen appears, instead of closing the tab/window, press "Close" at the top-left of the authentication screen to return to the app properly.
5. Try entering the card number manually (avoid auto-fill or camera scanning), and try re-registering the card from scratch.

If the error (Ref:2 / "Authentication failed") still appears after these steps, please contact us by phone or via the web inquiry form with the following information so we can investigate with the relevant department and call you back:

- Whether a button is visible at the bottom of the card registration screen, and if so, its color (if the button is gray, the entered details may not be accepted)
- A screenshot of the error and the type of card(s) you tried to register (e.g., Rakuten VISA, Amex)

Regarding account deletion: if you would still like to delete the account, you can do it yourself in the app under Account > Settings > Delete Account (per https://support-evcs.power-x.jp/hc/ja/articles/22879527604249). Please note that simply uninstalling the app does not delete the account, and choosing account deletion erases all registered information. Since you are a new registrant, there is no PowerX First membership to cancel beforehand.

We recommend trying the iOS update first, as it resolves this exact symptom in many cases. If it doesn't, please reach out with the details above and we will follow up.

Sorry for the trouble — this is a known pattern with card registration during new sign-up, and there are a couple of specific things to try before we escalate.

**Most likely cause on iOS**
The official Help Center article "クレジットカードが登録できません" (I cannot register my credit card) lists an iOS-specific issue: on iOS 15, credit card registration can fail. The fix is to update the iPhone to the latest iOS version and try again. This fits your case well, since it happens with several different cards (Rakuten VISA, Amex), which points to the device/app/payment session rather than the cards themselves.
/sources/ja/public-help/articles/24904289203097.md:26-29

**Steps to try (in this order)**
1. Update iOS to the latest version, then restart the iPhone.
2. Re-check the card number, expiry date and security code (CVC). Note that prepaid credit cards and debit cards cannot be used.
/sources/ja/public-help/articles/24904289203097.md:26-27
3. Enter the card number manually rather than using autofill / saved card data.
/sources/en/runbooks/billing.md:120
4. On the authentication (3D Secure) screen, when it shows "Authentication complete," press "Close" (閉じる) at the **top-left** to return to the app, instead of swiping the tab away. Dismissing the tab that way is what produces "Card registration failed (Ref:2)" / "Authentication failed."
/sources/en/runbooks/billing.md:120
5. If 3D Secure (本人認証サービス) is not yet set up on the card, complete the setup with the card issuer and retry.
/sources/ja/runbooks/billing.md:272

**If it still fails — what we need from you**
Please reply with:
- A screenshot of the app screen showing the error.
- The type/brand of the card you are trying to register.
- Whether the button at the bottom of the card-registration screen is visible, and if so, its colour (a grey button usually means an input mismatch; black means the form is accepted).
/sources/en/runbooks/billing.md:175-178
/sources/ja/public-help/articles/24904289203097.md:35-37

With that, we will hand it to the responsible department for internal investigation and arrange a call-back. I can't confirm any fix or system-side action until that team responds.

**If you would rather delete the account**
You can delete it yourself in the app: Account → Settings → Delete Account. If you are a PowerX First member, first go to Account → PowerX First management → Stop automatic renewal. Uninstalling the app does not delete the account, and deletion erases your registered information.
/sources/en/runbooks/membership.md:234
/sources/en/runbooks/corporate.md:97
/sources/en/runbooks/membership.md:27

If the in-app deletion option is not reachable because registration never completed, tell us and we will route the deletion request to the responsible department.

ご不便をおかけしており申し訳ございません。公式FAQと社内ランブックの内容に沿ってご案内いたします。

【原因として確認されている事項】
・カード番号・セキュリティコード（CVC）の入力誤り。あわせて、プリペイド式クレジットカードとデビットカードはご利用いただけません（楽天VISA・アメックスなどの通常のクレジット機能付きカードは対象です）。
・iOSをご利用の場合、iOSのバージョンが15だとクレジットカードを利用できないケースが確認されています。この事象はカード側ではなく端末・OS側に原因があることがあり、複数枚のカードで同じエラーが出るという状況とも整合します。まずはiOSを最新バージョンへ更新のうえ、お試しいただけますでしょうか。

【お試しいただきたい手順】
1. iOSを最新に更新し、端末を再起動する
2. カード情報を再登録する（自動入力ではなく、カード番号・有効期限・セキュリティコードを手入力する）
3. 認証画面が開いた後は、左上の「閉じる」を押してアプリに戻り、登録完了の状態を確認する

【それでも登録できない場合】
公式FAQでは、以下の2点をご連絡いただくようお願いしています。
1. クレジットカード登録画面下部にボタンが見えているか
2. 見えている場合、そのボタンの色（ボタンがグレーの場合は入力内容に相違がある可能性があります）
加えて、エラー表示が確認できるアプリ画面のスクリーンショットと、登録をご希望のカードの種類（例：楽天VISA、アメックス）をお送りください。社内でも確認のうえ担当部署へ連携し、折り返しご連絡いたします。お電話またはメールフォームからお問い合わせください。

【アカウント削除をご希望の場合】
アプリの「アカウント」→「設定」→「アカウントの削除」からご自身で削除いただけます。アプリをアンインストールしただけではアカウントやクレジットカード情報は削除されませんのでご注意ください。PowerX Firstにご加入中の場合は、先に「アカウント」→「PowerX First管理画面」で自動更新を停止してください。アカウント削除を選ぶと登録情報はすべて消去されます。
なお、登録が完了しておらずアプリ内で削除画面に到達できない場合は、担当部署にて削除対応が可能ですので、登録に使用されたメールアドレスとお名前を添えてお問い合わせください。
