The Jemulpo District Facility Management Corporation provides detailed schedules and application methods through QR codes on the Jemulpo Cultural Foundation’s website or promotional posters. At agricultural product distribution and price awareness campaign sites, scanning a QR code provides comprehensive guidance on freshness, quality, origin, and seasonal availability via short-form videos. All of these allow you to obtain information instantly without separate searches, saving time.

3. How to Apply for a Mobile ID or eSIM via QR Code?

To obtain a mobile resident registration card, present your physical ID at a nearby neighborhood office, fill out the application form, and then visit the issuing agency to scan the QR code to apply. In Bali, when using an eSIM, you can activate it immediately by scanning the QR code in your device settings without replacing the physical SIM card. Similarly, in Shanghai and Qingdao, China, eSIMs can be easily installed via QR code scanning without the need for a VPN. All these processes can be completed with just an internet connection, minimizing the need for additional paperwork.

5. What Should You Be Cautious About When Using QR Codes?

Before scanning a QR code, check your internet connection status, as unstable connections may cause information loading failures. Some events or services do not allow duplicate participation, so it is best to check the conditions in advance. Coupons or events with expiration dates must be used within the specified period to receive benefits. For security, only scan QR codes from trusted sources, and if personal information entry is required, always verify if it is an official channel. Keeping these points in mind will allow you to enjoy QR code benefits without inconvenience.

💡 Key Point
You should check internet status, duplicate participation restrictions, expiration dates, and security in advance.
