RFID basics and RFID module interfacing with Arduino

RFID stands for Radio Frequency Identification and is already in use in many industries. For example, RFID labels can be used to attach or implant into almost any item, which can then be used for identification and tracking purposes.

Today, through today's blog, we will discuss information about RFID and arduino RFID reader. You can find more information on our product detail page.

This passage is going to talk about the followings of the arduino RFID reader:

1) RFID Basics

2) RFID components

3) How do an RFID reader work?

1) RFID Basics

RFID stands for Radio Frequency Identification, which basically uses radio waves to read the information on a tag. RFID labels contain embedded transmitters and receivers that are attached to the object.

RFID is fast, does not require any contact between the reader and the tag, and can read them from a distance.

Radio Frequency Identification (RFID) technology is used to transmit information wirelessly via radio waves for data identification and tracking. It consists of an antenna, a transceiver and a transponder (called a tag or smart label).RFID systems also require appropriate software. Today, we typically see antennas and transceivers combined into a reader (also known as a scanner or interrogator.) The advantage of RFID is that it does not require physical contact or field connection wires.

2) RFID components

RFID systems consist of two parts: the tag and the reader

RFID labels

RFID labels contain a chip to store information about the physical object and an antenna to receive and transmit the signal. RFID labels can typically store 1 KB of data, but are sufficient to store names, credit card numbers, unique identification numbers, dates of birth and more.

RFID labels can be passive or active

A passive tag does not have a battery, it uses energy transmitted by a reader.

An active tag contains a built-in battery, which allows it to emit a stronger signal and increase the distance to 100 feet. Other features are the same as for passive tags.

RFID readers

An RFID reader performs two functions: transmitting and receiving. Therefore, you can also say that it is a transceiver. RFID readers contain an antenna, an RF module, and a control unit.

3) How do an RFID reader work?

The RFID reader generates a high frequency electromagnetic field, and when the tag is close to the tag, a voltage is induced in the tag antenna coil due to induction. This induced voltage is used as the power of the tag. In turn, the tag converts the signal into power and responds to the reader.

The last thing is to do the programming and debugging work. If you have questions, you can contact us for advice, we have professional staff to help you. If you need anything, you can contact us. You can also search for information about programming on the Internet. We hope you find this article helpful.

Different models of RFID readers have different connections, and I am not very professional, so you may need a professional to provide you with answers, please don't hesitate to contact us directly. We will give you the most perfect solution.

Hecere was founded in 2008. At beginning, our main business was smart cards, such as magnetic stripe cord, contact chip cord and RFID card.

In 2015, our company started to manufacture BFID label We gradually expanded our business rom smart cards to RFID labels.

In 2017. we integrated resources of RFID wristbands RFID keyfobs RFID anti-metol tag RFID reader RFID lock and so on, which bunt a powerful supply BEID products cham to meet our client's various requirements.
