Why buy an off the shelf product if you can make it yourself. That is what some guys at Cornell University decided to do when they needed an RFID reader. |

Hi,
I’m thinking of making 1 of this RFID security system. Can any1 provide me with the required Components and circuits diagrams to build them?

Hi Neo,
Click on the link within the article. There are schematics provided there.

hello!
your project is interesting, i plan to make one,can i get the shcematic diagram of your RFID reader?
June 9th, 2007
Hmmm…nice project. I should try to build this…
July 24th, 2007
can i have some explanation or the project description of this??
October 20th, 2007
we r doing a project on RFID .Quite inspired by ur homemade reader ckt n we would like
to make own reader ckt.actually requesting u to help us in our things. can u please
provide us with the basic reader circuit with components, becoz we tried at our level
n could do nothing much than just random search.or at least provide us with the
required information (reader circuit with comp,from where to avail the tag,) and any
more information if u can.
hoping a positive responce

Hi Veena,
The RFID project was featured here but created by someone else. Please click on the link in the article for more details. Let us know how the project turns out.

i have made the reader they have shown but im not still successful. the modulation from the rfid cards shows up but i have some problem with the later part of the circuit ingetting the modulation to be converted intostudents.also if someone has made this ckt and nice logic levels. anyways i m trying to sort it out . i think its some problem in my connections or ICs. good work cornell university students. also if someone has made this ckt and it works plz reply. the programming in the microcontroller atmga 32 is very cool and i have added many other facilities such as PIN code and LCD.

i doin project in airport for airbourn bags wat type of questions thy will ask. give me full details about rfid regarding airport
April 4th, 2009
Hi Karthi,
Looks like there are lots of large airports using RFID to track bags. Heathrow Airport is currently doing it.

Hi,
I wanted to know what type of rfid tag and reader could be used for the following two uses.
1. Employee login as the person passes through the door or gates
2. Tagging all the books in a library and using a reader finding on which row,shelf and distance the book is at.
Since I’m new to the concept of rfid,I dont know what frequency,type or memory is required and I really needed these details for a project.
HELP
May 25th, 2009
hii eby u can use passive tags for both purpose, for employee login the above project with tags in card form is best
. for library book tracking you will have to use smaller tags may be in sticker forms, if u just want to implement rfid and not get into deeper electronics u can buy modules from various companies like hid ,atmel, microchip & many more you can find the one nearest to you

Hi
I wanted to know whats the diiference between a 125KHz and 13.56MHz tag or reader.
What is the significance of these frequencies? Does it determine what read range it can achieve?
May 28th, 2009
you can use either 125khz lowFID or 13.56mhz hiFID both have almost same read range. they are only the standards fixed by the industry , also read range depends on reader module power in case of passive tags, in both the frequencies you can achieve a read range of max, 6 inches, (plz check with reader module you are using), if you require more read range (12-18 inches) you can use active tags. there are many types of tags available, also different coding and modulation techniques..in reader modules also many types are available with different interfaces serial, LAN wigeand wifi etc.. so you hav to select the tag and reader accoring to the application , the frequency standard does not matter

hello to all!
i have been trying to understand some specific RFID characteristics that i just can’t seem to grasp.
can specific location details be acquired ou are the location details determined by the reader and it’s position. put in other words: does the signal actually tell you where the tagged object is or do you know because of where the reader is and so you can deduce that it is somewhere in that range…
can an ID be redirected to a processor wirelessly? For example you have [ID1], [ID2] and [ID3] and 1=image, 2=sound and 3=video. can this ID be retrieved wirelessly so that it can be reproduced by a projector ou speakers?
thanx for any help in advance.
respect
–never let your curiosity wilt–
July 2nd, 2009
ok
practical and commercial applications of rfid detect the tag’s location according to its reader’s location , if u want location based identification u must use gps or some other wireless application
RFID is purely for identification and its range is less then 1 foot in most cases.
u can transmit wirelessly ID for images or audio etc but processing must be done in at the reciving end most tag consider data as raw binary..
but in case of rfid range is less if u want long distance communication use some other system as wi fi or bluetooth etc

salam.i want to make RFID reader as shown above,but along with this we have to implement as a whole a office based security system…as u have already done with the Reader can u tell me atleast the minimum time required to work on RFID reader making n also guide me about some components,i really need some help as i have very little time …really appriciate ur assistance….
July 17th, 2009
hii
ok the minimum time required is about 1 week, based on whwther the components are available and you want to make mior modifications and how well u master the compiler ,, the time can go up to 1 month,, if u want i can give u my report and also make u as many pieces u want,,.. plz reply with ur email id and where r u from..
August 3rd, 2009
hello,
i’ll be thankfull to you if u really provide me all the details regarding this whole project.plz send the block diagrams n some theory data…i am from pakistan if need pieces from u i’ll inform me.can u get me ur email id…i am from pakistan.i really need ur help….really appricate ur gesture.
thanks n waiting for ur reply.

Hi,
This is a passive RFID rite? Does anyone has an active RFID reader design?
July 22nd, 2010
hi,
Hi I would like to make a RFID reader which i can carry and scan different passive RFID tags fixed at different location and which stores the information eg. the Tag ID and the time it was scanned can you pls help me with this
August 5th, 2010
I am also interested in doing such kind of projects. please send me the appropriate materials.

I know that no one has posted here in awhile but I must say something. I love all the foreigners who has a horrible grasp of the English Language who are requesting schematics and code for this project.

Hi Sir,
I m doing b.tech final year project on rfid based attendance system.Can u suggest me about circuit diagrams and details of rfid reader and rfid passive tag.
i m waiting for ur reply.
January 25th, 2012
hello sir,
i am having a proj. using rfid’s on library system to replace barcodes. our existing module for passive rfid has a range of 10cm…is it possible to boost up the range up to 1 meter with my existing rfid reader?how will i do it is it necessary to use other devices so that the range would reach up to 1 meter? hopin for ur kind advice….tnx…
