RFID | Radio Frequency Identification and Detection

Table of Contents:

RFID is a tracking technology used to identify and authenticate tags that are applied to any product, individual or animal. Radio frequency Identification and Detection is a general term used for technologies that make use of radio waves in order to identify objects and people.
 
Introduction to RFID
Purpose of Radio frequency Identification and Detection system is to facilitate data transmission through the portable device known as tag that is read with the help of RFID reader; and process it as per the needs of an application. Information transmitted with the help of tag offers location or identification along with other specifics of product tagged – purchase date, color, and price. Typical RFID tag includes microchip with radio antenna, mounted on substrate.
 
The RFID tags are configured to respond and receive signals from an RFID transceiver. This allows tags to be read from a distance, unlike other forms of authentication technology. The RFID system has gained wide acceptance in businesses, and is gradually replacing the barcode system.
How RFID Works
Basic RFID consists of an antenna, transceiver and transponder. To understand the working of a typical RFID system, check the following animation.
Antenna emits the radio signals to activate tag and to read as well as write information to it. Reader emits the radio waves, ranging from one to 100 inches, on the basis of used radio frequency and power output. While passing through electronic magnetic zone, RFID tag detects activation signals of readers.
  
                              
 
Powered by its internal battery or by the reader signals, the tag sends radio waves back to the reader. Reader receives these waves and identifies the frequency to generate a unique ID. Reader then decodes data encoded in integrated circuit of tags and transmits it to the computers for use.

this information very good; I

this information very good; I need more...

Its like you read my mind!

Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something. I think that you could do with some pics to drive the message home a bit, but other than that, this is great blog. A great read. Ill definitely be back. Regards, Felton

 u know m beginner in

 u know m beginner in embedded system..nd i love the circuits and also programing on hardware..when i found this site m shocking dat it is great for me as a beginner..thanks for making such a informative website..gud keep it up i think dat plz update about the latest updates in embedded system..

 thnx man

 hi all,     Am doin a

 hi all,

 

  Am doin a project based on rfid to detect staff and students in a college. So am using a rfid reader module, pc and PIC16F8777A to complete my prjct. Bt am confused about the database to be created.. can any one please help me regarding the software 2 b used....and my intension is to display the position of a particular person  via pc..

hello..... i just saw ur msgs

hello..... i just saw ur msgs on a wbsite regarding rfid based projects.......... if u havnt complte ur projct yet........ then i can help u as much as i have.......... so u can reply me whn evr u needed.......tcz 

best regards

saeed

I HAV DONE SUCH DESIGN BEFOR

I HAV DONE SUCH DESIGN BEFOR USING JAVA AND  MYSQL FOR D DATABASE , AND ALSO I DID DAT RECENTLY USING C#.NET AND ACCESS. THEY ARE APIs IN JAVA DAT ALOWS U TO READ YOUR RFID READER BCOS IS AN HID DEVICES. ALL YOU HAV TO DO IS TO FIRST REGISTER ALL D CODES FROM EACH TAGS , TRHEN MAP THEM TO EACH STAFF AND POSITION IN A TABLE OT FLAT FILE OR IN XML FORMAT.

SO WHENEVA A TAG IS BROUGHT CLOSE TO  THE READER , CODE IS TAKEN TO THE APPLICATION  AND D APP WIL COMPARE THE RED CODE WITH THE POSITION MAPPED IN D DATABASE OR THE FLAT FILE. SIMILARLY  , I DID IT WITH C SHARP DOT NET . PRETTY SIMPLE AND EASY

thanks .......... it's good

thanks .......... it's good information about rfid system ........also require some more about program.........n circuit diagram.......

its very useful........

Can any one help me..

my project is on 8051(RFID based auto toll plaza).I am not able to understand how tag is read serially using RFID.I am not able to write C code for this.

I am doing a project based on

I am doing a project based on application of rfid.

I just want the interconnection diagram between rfid and pic 18f4520 controller.Also if possible some help is required in coding.

I am using Micro C for coding purpose...I just want to compare the recieved data of tag with the data inside the controller and make a particular pin high.

Thank you..!!!
