How do NFC tags work?
NFC (Near Field Communication) tags utilize electromagnetic induction to facilitate communication between devices.
NFC tags contain a small chip and an antenna, which work together to store and transmit data.
There are two main modes of operation in NFC: read/write mode and card emulation mode.
This mode is commonly used for applications like contactless payment and information sharing.
When an NFC-enabled unit approaches an NFC tag, an electromagnetic field is generated by the devices NFC antenna.
The NFC tags antenna picks up this electromagnetic field and converts it into electrical energy.
The tag then uses this energy to power its chip and start communicating with the machine.
The reader sends out a signal containing specific commands to the tag, and the tag responds accordingly.
The data transmission between the reader and the tag occurs through modulation of the electromagnetic field.
This is known as load modulation.
NFC tags can store various types of data, such as URLs, contact information, or text messages.
In addition to the read/write mode, NFC tags can also operate in card emulation mode.
Their versatility and ease of use make them a valuable tool in various industries and applications.
Understanding the different types of NFC tags can help you choose the most suitable one for your specific tool.
