RFID induction question and frequency

In summary, passive RFID tags require induction to function. They are powered when the induction reaches the tag and then a microcontroller sends an RF signal to the reader with the product ID. The type of induction used, how the induction frequency does not affect the tag's frequency, and the standard protocol for sending product IDs vary and can be found on the RFID Wikipedia page.

Well, passive RFID tags has to be inducted to work. When the induction reaches the tag, it powers itself and then the microcontroler sends a RF signal to the reader, with the product ID, rigth?

What I want to know is: what type of induction does it use? How the induction radio frequency doesn't affect the frequency generated by the tag? What's the standard protocol used by the passive RFID tags to send the product ID of themselves?

Thanks :)

What is RFID induction?

RFID (Radio Frequency Identification) induction is a technology that uses radio waves to automatically identify and track objects or people. It involves using small electronic devices called RFID tags or transponders, which contain a unique identification number and can communicate with a reader through electromagnetic induction.

How does RFID induction work?

RFID induction works by using a reader or scanner to send out a radio signal and power the RFID tag. The tag then responds by transmitting its unique identification number back to the reader. This process is known as backscatter and allows the reader to identify and track the tagged object or person.

What is the frequency used in RFID induction?

The frequency used in RFID induction varies depending on the application and the type of RFID technology being used. The most common frequencies used are low frequency (LF), high frequency (HF), and ultra-high frequency (UHF). LF operates at 125-134 kHz, HF at 13.56 MHz, and UHF at 860-960 MHz.

What are the advantages of RFID induction?

RFID induction offers several advantages over traditional identification and tracking methods. It allows for automatic and contactless identification, reducing the need for manual scanning and data entry. It also enables real-time tracking and monitoring, improving inventory management and supply chain efficiency. Additionally, RFID tags can be read from a distance and through materials, making them suitable for various environments and applications.

What are the potential concerns or limitations of RFID induction?

Some of the concerns or limitations of RFID induction include potential privacy issues, as the technology can be used for tracking individuals without their knowledge or consent. There are also concerns about the security of the data transmitted and stored on RFID tags, as well as the potential for interference or collisions in highly populated RFID environments. Additionally, the cost of implementing RFID technology can be a barrier for some businesses or industries.
