This App can scan QR code and display those contents. You can also send and share this information to others via SMS, E-Mail, Kakao , etc. Especially, in case of QR code including GPS information, it can be shown in the map with PIN point of it, and you can tap Navigation app with destination setting automatically. So you don't have to type and search your destination. Also, If you select QR code from photo album stored in your phone, it can be shown by scan photo and also you can send contents to others you want, and you can set the location at map and start navigation app with those coordination values as destination.
It is difficult(even dangerous!!) to search destination with small virtual keyboard in the car. so this can easily help you out. You can select which kind of map to be sent when sending GPS information via messenger. This feature can support sharing those with other phone as well as iPhone. User can select favorite navigation apps, but should be installed previously for normal operation before use. Not only destination scanned via QR code but also you can send GPS location information of current position as destination. This feature is very useful in situation of sudden change of meeting place.
