If you're unable to make a payment at a store that accepts My Code payments, it may be because:
• You're connecting 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.
• The code is old
Codes are only valid for five minutes. Tap Refresh and try making the payment once again with a new code.
• You don't have enough money in your LINE Pay balance
Try making a My 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 My Code payment. Select LINE Pay balance as your payment method, read the important notes, and 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 and it can be scanned.
• The cashier at the store didn't select LINE Pay
Tell the cashier again that you are paying with LINE Pay.
