What are NFC tags?

NFC (Near Field Communication) technology utilizes wireless radio frequency signals to enable short-range communication between smartphones and NFC tags.

The main type of NFC tags commonly used is based on the ISO 14443A standard.

These tags have the capability to be both read and rewritten by users, but can also be configured as read-only if desired.

They typically possess a basic memory size of 144 bytes for Ntag213, but you can have a maximum of 4K for Desfire. The communication speed for NFC tags is generally around 106K bit/s.

Some notable chip types frequently used in NFC tags include Ultralight, Ultralight C, and NTag213/215/216, Desfire 1K, and Desfire 4K.

How does NFC work?

When an NFC device, like an NFC smartphone, tablet, or reader, comes into proximity with an NFC tag, the tag receives a signal and transmits the information stored in its chip to the NFC device.

The NFC device then processes the received information and performs the appropriate actions based on the instructions provided.

Is NFC tag safe?

NFC tags are generally considered to be safe and secure. They have a unique UID (Unique Identifier) that cannot be easily duplicated, ensuring their authenticity. 

Additionally, NFC communication operates at a close proximity range, which reduces the risk of data being intercepted or accessed without authorization from a distance. As a result, users can have confidence that their information is protected when using NFC tags.

How to program NFC tags?

To program NFC tags, you will need to follow these steps:

  • Purchase NFC tags that are suitable for your project. These can include NFC stickers, NFC cards, or custom-made tags based on your requirements.

 

  • Ensure you have an NFC-enabled device, such as a smartphone, that supports NFC functionality.

 

  • Visit your smartphone’s app store and search for the NFC Tools App. Download and install it on your device.

 

  • Open the NFC Tools App and input the desired content or information that you want to program onto the NFC tag.

 

  • Bring the NFC tag close to the NFC reader/writer of your smartphone. The NFC Tools App will detect the tag and prompt you to write the programmed content onto the tag.

 

  • 6. Follow the on-screen instructions to complete the programming process. Place the NFC tag on the designated part of the smartphone where the NFC reader/writer is located until the writing process is complete.
