NFC Tags What They Are How They Work And 21 Amazing Uses

What are NFC tags

NFC tags are devices that can be set to perform certain functions automatically when read with a smartphone. These tags have an NFC chip inside, on which you can write to program-specific tasks, such as activating the phone’s do not disturb mode or going directly to a website. By the way, it should be mentioned that these tiny devices get their power from the mobile phone that reads them.

Their types can differentiate the NFC chips present in the tags, NTAG being the most common of them, but the essential characteristic is the memory capacity. The data stored in them will depend on this specification, which is measured in bytes. For example, this depends on whether you can keep 100 or 400 character text, including URLs. The size is also essential because the bigger they are, the greater the distance you can read them.

NFC tags typically have an adhesive back so that you can stick them on before use. For example, you can stick them on the bedside table and configure them so that, just by bringing the mobile closer, it becomes silent before sleeping.

In short, they are handy devices that allow you to save time by automating activities. Of course, when you buy a new one, it’s up to you to configure it, something that we will learn to do right now.

How to set up an NFC tag

Well, you bought an NFC tag to automate tasks with your smartphone, but how can you configure it? When you buy a label with this connectivity, it comes without information, completely blank, so you are the one who must write on it to tell it what to do when it reads it with your mobile.

Fortunately, you don’t have to have advanced knowledge to do this, as there are free Android apps specifically designed to set up NFC tags. The best is NFC Tools, as it allows you to write text, links to web pages, email addresses, phone numbers, addresses of an exact location, a configuration of the WiFi connection, and even a GPS location on those labels.

To do this, the first thing you should do is download the NFC Tools app on your smartphone, which has to have an NFC chip. Once installed, open it and follow these steps:

  1. Click on the “Write” tab.
  2. Tap on “Add a record” to start choosing the action to automate.
  3. Select whether to add text, URL, custom URL, a link from a specific search, a social media profile, a link to a video, file or app, an email address, a contact, a phone number … Finally, one of the many options available in NFC Tools.
  4. Configure the registry, in our case, by entering a URL. Click on “Validate” when you are done.
  5. Now, click on the option “Write / X bytes” to write this action in the NFC tag. This same option informs you about the size of the action that you are going to report on the label, very useful to know if it will have space or not.
  6. Bring the phone closer to the NFC tag to finish the process.

When you have finished the configuration, you will only have to put the NFC tag in the place where you will use it and bring your smartphone close to it so that the programmed action is carried out automatically.
