Automated Smartphones

But let’s start from the beginning. What exactly is NFC? NFC stands for Near Field Communication and describes the technology of communication between smartphones, which can be carried out in the close environment around the smartphone via a small sensor. Either the NFC chips of two smartphones can communicate with each other and start a file transfer, for example, or, as with this gadget, communication via an NFC tag is possible. The NFC tags are available in different forms, such as key fobs or stickers. In this video you can see how the parts work:

In this offer you get a set of 10 NFC Tags, which are equipped with an adhesive backside. You can simply stick them on wherever you need them and then hold your mobile phone to the tag for communication. With a diameter of 27mm the tags are relatively small and inconspicuous. They offer you 144 bytes of memory, which can be rewritten up to 100,000 times. For this you need a suitable app, of which there are also many free variants, such as the NFC Tasks Launcher. To read it you just have to hold the NFC sensor of your mobile phone to the day and this can happen as often as you like. All phones with NFC are supported. So the best thing to do is to check if your mobile phone can support NFC.

If you’re wondering why you need it all, here are a few more scenarios: Whenever you go to bed in the evening, you set your phone to silent because you don’t want to be thrown out of bed. But since you’ll have to get up at some point, the alarm will go off quickly. With an NFC tag you can save yourself these steps. Just hold the phone to the tag and the steps will be executed on your phone. Another example is calling up a profile when you are on the road with your smartphone in your car. The WLAN can then be switched off automatically and a connection to the radio established via Bluetooth. It would also be possible to start a navigation app automatically. There are loads of different uses for the tags.
