All you need to know about NFC tag

 

In this article, we'll be discussing everything you need to know about NFC tags. This includes an overview of what NFC tags are, how they work, and some of the potential applications for them.

By the end of this article, you should have a good understanding of what NFC tags are and how they can be used.

What is NFC tag and what are its uses

An NFC tag is a small chip that can be embedded in everyday objects like keycards, posters, or even your smartphone. When an NFC-enabled device, such as a smartphone, comes into close proximity with an NFC tag, the two devices can communicate with each other wirelessly. NFC tags can be used for a variety of applications, including contactless payment, data sharing, and simple automation tasks.

You could use an NFC tag to store your home WiFi password on your keychain. Then, when you get home, your phone could automatically connect to your WiFi network by reading the NFC tag. Or, you could use an NFC tag to launch a specific app on your phone when you tap it against a poster.

How do NFC tags work

NFC tags contain a small amount of memory that can be used to store information. This information can be read and written to by an NFC-enabled device. When an NFC-enabled device, such as a smartphone, comes into close proximity with an NFC tag, the two devices can communicate with each other wirelessly. The NFC-enabled device can read information from the NFC tag, or write information to the NFC tag.

NFC tags are passive devices, which means that they do not require a power source to work. They are powered by the electromagnetic field generated by the NFC-enabled device when it comes into close proximity with the NFC tag.

How to create an NFC tag

Creating an NFC tag is a simple process. All you need is an NFC-enabled device and an NFC tag. You can purchase NFC tags online or at some electronics stores.

To write information to an NFC tag, you will need to install an NFC writing app on your NFC-enabled device. Once the app is installed, you can write any desired information to the NFC tag.

Common uses for NFC tags

There are a variety of potential applications for NFC tags. Some common uses for NFC tags include:

• Contactless payment: NFC tags can be used to make contactless payments with your smartphone. All you need to do is tap your phone against an NFC-enabled payment terminal.

• Data sharing: NFC tags can be used to share data between two NFC-enabled devices. This is useful for sharing contact information, photos, or other files.

• Automation tasks: NFC tags can be used to automate simple tasks on your smartphone. You could use an NFC tag to launch a specific app, or to toggle your phone's WiFi on or off.

NFC tags are a versatile technology with a variety of potential applications. In the future, we may see NFC tags being used in even more innovative ways.

what does no supported app for this nfc tag mean

If you see the message "No supported app for this NFC tag" it means that your phone does not have an app that can read the information stored on the NFC tag.

In order to read the information on the NFC tag, you will need to install an NFC writing app on your phone. Once the app is installed, you should be able to read the information on the NFC tag.

If you are unable to find an NFC writing app, you can try searching for "NFC tag apps" in your app store.  There are a variety of NFC writing apps available for both Android and iOS devices.
