You cannot use the "QR Check-in" feature in KakaoTalk when the "Block internet search in KakaoTalk" function is enabled, as this feature also connects to internet pages.

If you disable the "Block internet search in KakaoTalk" function to use QR check-in, internet searching via the # (sharp) search within the KakaoTalk app will become possible, and visits to websites will not be monitored, nor will harmful sites be blocked. Additionally, even if you use features like KakaoTV, games, or internet search within the app, it will only be aggregated as KakaoTalk usage time; therefore, it is recommended to keep the "Block internet search in KakaoTalk" function enabled by default.

If you need "QR Check-in," you can perform QR authentication using the following two methods instead of KakaoTalk.

1. Using the carrier's PASS app

If you enable the "Display immediately upon app launch" feature, the QR screen will appear immediately after logging into the PASS app, allowing for convenient authentication.

2. Using the Naver site in the Chrome browser

Since websites accessed using apps other than Chrome, such as Naver, Daum, or Samsung Internet, are not monitored, it is highly recommended to enable the "Block browsers other than Chrome" feature to ensure harmful content blocking and website monitoring are effective.
