The Samsung Galaxy Watch 4 is a great smartwatch and you can do a lot of things with the watch. However, now you can also generate QC codes to store information on the watch and access it anytime later on. The QR code can be as basic as some text information or it can be also a payment app QR code. The best way to do this is to install an Android app on your smartwatch and also on your phone. The app is absolutely free and also can be installed on both your phone and watch.

Once you have installed you can add the QR codes by just connecting the app to the phone. On the phone, you need to just add the QR codes and then press the sync option so that the QR code can be synced to the watch directly which later can be accessed anytime. The best thing is all the QR codes can be later accessed on the watch itself. You just need to scan the QR codes with the QR code scanner to get the required info on the watch.
