You’ve probably heard of Xperia SmartTags or Samsung TecTiles, which are small pendants and stickers that activate your device to perform defined actions using Near Field Communication technology. Extremely useful for recent devices that have NFC built in, older devices without this technology may miss out on such practicality. But fear not, because Smart(QR)Tags seek to emulate this same experience for everyone.
Independently developed by XDA Senior Member inteks, Smart(QR)Tags essentially emulates the same functionality as NFC SmartTags and TecTiles by utilizing your device’s camera rather than NFC technology. By scanning a QR code, which can be easily generated on the Internet, the app activates your device to perform user-defined actions such as switching profiles, launching an app, playing music, and activating WiFi tethering, among many other actions.
Now, you may wonder, why go to a QR scanning app, open it, aim it, and wait for the action when you can just perform the action yourself? The answer is, you don’t. Inteks has allowed users to activate the actions just by unlocking the device, shaking it, and aim. The shake sensitivity and duration can easily be adjusted with simple horizontal scales in the app settings. So for all you who stare longingly at your friends and colleagues who just love to show off their SmartTags or TecTiles, you too, can have fun with these tags. Generate a code, set it up with the app, and put it up on the door or the car dashboard. It’s simple.
