The up-to-date List of all NFC-enabled Smartphones and Tablets, and their Compatibility with .
Tags can be read-only or read-write, where data can be added by the reader or existing data overwritten. The read range for RFID tags varies based on factors including type of tag, type of reader, RFID frequency, and interference in the surrounding environment or from . A simple introduction to how RF and RFID tags are used in smart cards, toll collection, shop security, and other everyday applications. The main function of an RFID reader is to send an electromagnetic signal to the RFID tag and receive the data stored within it. Unlike traditional barcode systems, which require line-of-sight scanning, RFID readers can capture data .Data stored within an RFID tag's microchip waits to be read. The tag's antenna receives electromagnetic energy from an RFID reader's antenna. Using power from its internal battery or power harvested from the reader's electromagnetic field, the tag sends radio waves back to .
Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object.
The working principle of RFID tags is based on the propagation of radio waves. Here are the detailed steps of how they operate: Data Storage: The microchip inside the RFID tag stores the tag’s unique identifier and any additional data. This data is transmitted during communication between the tag and the reader.

Data transfer: When energized by an RFID reader’s radio waves, the tag’s antenna receives power and activates the IC. The IC then modulates the radio waves and backscatters them to the reader, transmitting the stored data (UID and additional information).A basic guide to getting started with the RFID Tag Reader breakout and how to read and write multiple RFID tags over multiple feet!
RFID readers communicate with tags through radio waves. It first emits a radio frequency signal. When the tag enters the signal range of the reader, the tag’s antenna captures the signal and activates the chip. The tag then sends the data in the chip to the reader through the antenna.Tags can be read-only or read-write, where data can be added by the reader or existing data overwritten.

The NFC Reader Mode is a powerfull way to communicate with NFC tags. For most use cases it is more reliable and more easy to use, compared to the (older) Intent-based way.
