QR Codes provide valuable services in many areas. It is therefore not surprising that they have also found their place in smart home devices and IoT applications. IoT stands for the "Internet of Things" and describes the networking of devices via the internet, enabling automation and remote control.
A few years ago, it was almost unimaginable that everyday objects could be controlled via an internet connection. Today, however, we are fully connected - a smart home system can centrally control lighting, heating and household appliances, and a doorbell can send live images directly to our smartphone if we wish. Many of these possibilities work thanks to QR Codes, which enable a quick and easy connection.
