WOWPASS Card Is Not Working

If your WOWPASS card is not working, this WOWPASS Troubleshooting Guide will help you find the cause and choose the right solution.

Possible Reasons

Your WOWPASS card may not work because:

• The WOWPASS payment balance is too low for a store purchase.
• The separate transportation balance is too low for subway or bus travel.
• The payment terminal has a temporary problem.
• The card was not used as required by the merchant terminal.
• The card is damaged or cannot be read.

How to Fix It

Try these steps in order:

1. Check the balance that matches the problem: WOWPASS payment balance for store purchases or transportation balance for subway and bus travel.
2. Confirm that the correct balance is available for the action you are trying to complete.
3. Follow the current reader or terminal instruction before trying the card again.
4. If the device appears to be the problem, ask staff or use another available terminal or gate.
5. Restart the WOWPASS app and check for any notifications.

If the card still does not work, check the current card status in the official WOWPASS app and use official WOWPASS support when needed.

When to Contact WOWPASS Support

Contact WOWPASS Support if:

• Your card cannot be recognized.
• Your balance is correct, but every payment fails.
• Your card appears to be damaged.
• The problem continues after trying all of the steps above.

WOWPASS App Is Not Working

If the WOWPASS app is not working, separate the app problem from the physical card problem. The card may still work even when the app has a connection or login issue.

Common App Problems

You may experience one of these problems:

• The WOWPASS app does not open.
• You cannot log in to your account.
• The app keeps loading.
• The app shows a network error.
• The app closes unexpectedly.

How to Fix It

Try these steps in order:

1. Check that your phone is connected to the internet.
2. Close the WOWPASS app and open it again.
3. Make sure you are using the latest version of the app.
4. Check your login information and try again.
5. Restart your phone if the app still does not respond.

If the problem continues, check current WOWPASS service information and contact official support if you still cannot access the app.

Cannot Register the WOWPASS Card

If you cannot register or connect your WOWPASS card in the app, follow the current on-screen process first. Menu names and registration steps can change after an app update.

Possible Reasons

You may not be able to register your card because:

• The card information was entered incorrectly.
• The internet connection is unstable.
• The WOWPASS app needs to be updated.
• The card has already been registered.
• A temporary server error has occurred.

How to Fix It

Try these steps in order:

1. Check that you entered the correct card information.
2. Make sure your internet connection is stable.
3. Update the WOWPASS app to the latest version.
4. Close the app and try the registration again.
5. If you suspect a temporary service problem, check current WOWPASS service information before repeating the same registration step.

If you still cannot register your WOWPASS card, contact WOWPASS Support for further assistance.

Balance Is Incorrect

If a balance looks incorrect, first confirm which balance you are checking. WOWPASS payment balance and transportation balance are separate.

Possible Causes

Your balance may appear incorrect because:

• A recent transaction has not been updated yet.
• The app has not refreshed your latest balance.
• Your internet connection is unstable.
• A temporary system delay has occurred.

Check Recent Activity First

Review recent payment or top-up activity before assuming that the balance itself is wrong.

Refresh the relevant screen and compare the balance with recent activity. If you still cannot explain the amount, use official WOWPASS support.

Refresh the Balance

Try these steps:

1. Make sure your phone is connected to the internet.
2. Open the WOWPASS app again.
3. Refresh the balance or reopen the card screen.
4. Check your recent transaction history.

When to Contact WOWPASS Support

Contact WOWPASS Support if:

• Your balance still looks incorrect after refreshing and reviewing recent activity.
• A completed payment is missing.
• The balance does not match your recent transactions.

Payment Was Declined

If a store payment is declined, check the WOWPASS payment balance, card status, and merchant terminal before deciding what to do next.

Possible Reasons

Your payment may be declined because:

• Your WOWPASS balance is too low.
• The store’s payment terminal has a temporary problem.
• A temporary system error has occurred.
• The card was not used as required by the merchant terminal.
• The merchant does not accept the payment at that time.

What to Do Next

Try these steps in order:

1. Check your WOWPASS balance in the app.
2. For a normal store payment, follow the current merchant terminal instruction and insert the card’s IC chip when required.
3. Ask the store staff whether the transaction can be tried again.
4. Try another payment terminal if one is available.
5. Use another payment method if the problem continues.

If your payment is still declined after trying these steps, contact WOWPASS Support for further assistance.

Cannot Top Up the Card

If a top-up does not work, first identify whether the problem involves payment balance top-up, transportation balance top-up, the app, or a kiosk. These can use different current methods.

Possible Reasons

You may not be able to top up your card because:

• The cash was not accepted by the kiosk.
• Your payment card was declined.
• The WOWPASS kiosk is temporarily unavailable.
• A temporary machine error has occurred.
• Your internet connection is unstable if you are using the app.

How to Fix It

Try these steps in order:

1. Check that your cash or payment card is accepted.
2. Read the current error message before retrying the top-up.
3. If the kiosk appears to be the problem, check the official WOWPASS app or guide for another current supported method.
4. Restart the WOWPASS app if you are using it.
5. Contact WOWPASS Support if the problem continues.

Do not repeat the same transaction when the kiosk shows an error. Follow the current screen message and check official WOWPASS information for another supported option if needed.

WOWPASS Does Not Work on the Subway

If WOWPASS does not work at a subway fare gate, check the separate transportation balance first. The WOWPASS payment balance cannot replace the transportation balance.

Common Reasons

Your WOWPASS card may not work because:

• Your transportation balance is too low.
• The card was not used as required by the merchant terminal.
• The ticket gate has a temporary problem.
• The card could not be read properly.

How to Fix It

Try these steps in order:

1. Check your transportation balance in the WOWPASS app.
2. Tap only the WOWPASS card once and wait for the fare gate to respond before trying again.
3. Try a different ticket gate if one is available.
4. If the transportation balance is low, follow the current top-up option shown in the official WOWPASS app or guide.
5. Ask a station staff member for assistance if the problem continues.

If your WOWPASS card still does not work after trying these steps, contact WOWPASS Support for further assistance.

Kiosk Is Not Working

If a WOWPASS kiosk is not working, read the message on the screen first. Kiosk availability and supported services can change, so do not assume that the same service must be available at every kiosk.

Possible Problems

The WOWPASS kiosk may not be available because:

• The kiosk is out of service.
• Temporary maintenance is in progress.
• A payment error has occurred.
• The kiosk cannot connect to the network.
• The kiosk is temporarily unavailable.

How to Fix It

Try these steps in order:

1. Read the message shown on the kiosk screen.
2. If the kiosk is restarting or under maintenance, check another current service option instead of repeatedly starting the same transaction.
3. Check the official WOWPASS app or website for another current kiosk or supported method.
4. Make sure your payment method is accepted.
5. Contact WOWPASS Support if you cannot complete your transaction.

If another current option is available, use the one that matches the service you need.

Lost Your WOWPASS Card

If you lose your WOWPASS card, protect the card balance first and then check the current replacement process.

What to Do Immediately

Act as soon as possible.

1. Open the official WOWPASS app and go to the current card security or management area.
2. Use the current card pause function to protect the card if it is available for your account.
3. Follow the current lost-card instructions shown by WOWPASS and contact official support when required.
4. Follow the instructions from WOWPASS Support for your account.

Get a Replacement Card

If you need another card, follow the current official replacement process. Replacement eligibility and steps can depend on card and account status.

If your account is eligible, you may be able to register a replacement card and continue using your WOWPASS services.

Forgot Your Account Information

If you cannot access your WOWPASS account, use only the current official account-recovery process shown in the app or by WOWPASS support.

Common Problems

You may not be able to sign in because:

• You forgot your password.
• You entered the wrong login information.
