If you're unable to make a payment at a store that accepts code payments, it may be due to one of the following reasons.
• You're connected to a Wi-Fi network.
You may get a security error if you're connected to a store's Wi-Fi network. Disconnect from the Wi-Fi network and try making the payment once again.
• Your Visa LINE Pay credit card was not registered to LINE Pay properly (for using Add & Pay as your payment method).
For information on how to register your Visa LINE Pay credit card, see this Help article
Note: If you want to use your LINE Pay balance as your payment method, tap Add & Pay at the top of the LINE Pay main menu and select LINE Pay balance.
• The code has expired.
Codes are only valid for five minutes. Tap Refresh and try making the payment again with a new code.
• You don't have enough money in your LINE Pay balance.
Try making the code payment again after adding money to your balance.
Note: You can check your balance from the My Code screen and the LINE Pay main menu.
• You didn't select a payment method.
You need to select a payment method the first time you make a code payment. Select LINE Pay balance or Add & Pay next to Payment method, read the important notes, then tap OK.
• Your screen is too dark or the code is not fully displayed.
Your code cannot be scanned if your screen's brightness is set too low. Make sure to increase the brightness before making a My Code payment. Also, your code may not fully appear depending on the size of your smartphone's screen. In this case, adjust the screen so your code is displayed completely.
• The cashier at the store didn't select LINE Pay or PayPay as the payment method.
At LINE Pay merchants, tell the cashier that you are paying with LINE Pay. If you're paying by scanning a PayPay QR code, tell the cashier that you are using PayPay.
Note: You may not be able to make code payments at some PayPay merchants, even if they accept making payments by scanning a QR code.
