Hey guys today I just got an RFID Reader module from Parallax! I tried it out and made this program which identifies cards and other RFID products! All you need is a computer, an Arduino, a breadboard, and the Parallax RFID Reader Module! Please share your experiences, I am in wonder of what may have happened to you while building it or something like that! Thanks.

Step 1: The Circuit!

This is a very simple circuit which only needs four wires! (besides the usb) Down below is a diagram!
<p>would this dump every credit card info? 3:) im thinking about something bad jk</p>
<p>Not this specific sensor, but a sensor with a different frequency can pick up the Credit Card information. (dependant on which technology)</p>
Hey guys I made a second version feel free to check it out :D and thanks for your comments :D
hi i got the rfid going on my arduino uno. but i cant figure out how to make a led on pin 13 turn on when a specific card is read.also how wold i Chang the name of the card so when it reads a2r128 a1r120 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a0r-1 a1r248 a4r128 a6r128 a10r120 a13r0 a17r120 a19r128 a18r0 a17r128 a16r128 a15r0 a14r120 a13r120 a12r120 a11r248 a10r128 a11r120 a16r128 a19r248 a23r0 a26r120 TAG: and change that to: joe hudy. and with that name &quot;joe hudy&quot; i cold put it on my lcd.
I'm publishing a newer version of this instructable soon, it is going to incorporate the card code comparing.
You cannot change the name of the card because this is only a reader, but you can assign a name and value for the card. For Example lets say you want to have a vending Machine account, you can enable a card on the system when you buy it. You could set the name and when you scan it it goes into the system. Under the Name there could be a value which could be changed like subtracted when you spend money or added when you put money in the account.
i was wondering how can you add a display to this code? maybe one of the touch screen LCD's? i have one of those i wanted to view on that. and my <br>C++ is at a beginners hello world basically...
Well can you please specify which LCD you are talking about?
it says HY-tft320_262k under, it has a SD card slot also.
can you give me the product page, then I should be able to help you, Thanks Simon
DB0-DB16 to pin D0-D13, pin A0-A1 of Arduino<br>RESET to A2<br>CS to A3<br>WR to A4<br>RS to A<br>this should take up most of the pins on the Arduino UNO, so you would need an Arduino Mega for this to function.
i have uno and mega<br>
Ok then, you will need to edit the code then. You will need to use multi-serial on the mega and change the Enable port to 50. Or something like it. <br>Then programming the LCD is necessary. I will try to make a sample code for you of the RFID and everything when I get a chance. That should be soon
thank you so much =)<br>
did you already buy this? I have something similar but I like it better.
what did you have by the way?
well I bought a few products for <a href="http://4dsystems.com.au" rel="nofollow">4D systems</a>&nbsp;and they work well with Arduino. I love their products. I am trying during my free time from school to work on your problem.
I yes i have it in possession now. Was so curious what i can do with this thing.
