RFID READER HELP

Hello, can anyone help me design an RFID reader which can tell me when something is missing. I would like to build a reader for my file cabinet. I know this is hard but the reader will have to keep reading the files by maybe pinging and when a file is missing from the cabinet an LED will light up and maybe a small readout telling me what file is gone. Cabinet is small only 300mm so if anything is more than 300mm away from the reader it will light up. Can anyone help?

I just want a cheap multi card reader to put in one of my bays, here is my motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131874.

Please keep the price under $25 I am only going to be doing this for things like plugging in SD cards and such but if I will have the option to get a 75-in-1 card reader for the same price, I am taking that one. Thanks!

How to reprogram this NFC reader?

So I've got this NFC mobile banking from work (we've shut down the system because of lack of users) and we were left with a few hundred of these "read-write" NFC things. As you can see from the photos they have 2 SIM-card holders (probably that is the way they were connecting to the network) 2 USB mini ports, a RGB screen, a small speaker, and the board which is made of 2 easily disconnected parts. If I try to connect it to my PC it gets stuck on "Time and date set" and after a minute it writes a "Failed" on the screen. What i want to do is to make it able to read/write NFC chips and to display text on the display. Please help me because I have no idea hot to do this.

Use an USB fingerprint reader to log in Answered

Interfacing the arduino with the parallax RFID reader? Answered

I want to interface the parallax RFID reader with the arduino.  I have done some research and found some programs, but I can't quite understand what is going on it the programs.  Here is one that I found on the arduino playground: www.arduino.cc/playground/Learning/PRFID I couldn't paste the code, because when I did it just went on one line, but the program I looked is the first one. The questions I have are: char code[10] ---- what does the 10 mean? Also how does the program read each byte individually, and then combine them into the whole byte string for the rfid tag. I am just learning about using serial with the arduino so not much in the program made sense to me and the programs didn't say how they worked. Thanks in advance!

Creating a 433.92MHz receiver to read active RFID tags.

For my senior project I am using an active RFID tag and I need to be able to read it from a range of distances, ideally it can be read from 200ft away. I've been able to find active tags for a reasonable price, but I can't find active readers for less than $500. I am hoping there is a way to create my own reader. The frequency active tags use is 433.92MHz do you think I could use a RF receiver or transceiver to read the tags? I'm going to be using the Arduino Uno.

Laptop's fingerprint reader, is it possible to reuse it on desktop?

The dead laptop is a HP Pavillion dv3 4010sl, the sensor is a Validity VFS301 (cdk1071_r04_hf) as written on the sensor itself. if i remember correctly it was shown as a USB peripheral. maybe is simple and it need just some resoldering to a USB cable, the problem is that the flat cable connecting it to the motherboard has 6 pins/lines and my knowledge in electronics is quite limited... I've found online what seems like a motherboard schematics (pg.48) and the vendor's sensor's manual. Does Anyone knows if is possible, If yes how?

cassette/tape deck sensors/readers; what can I do with them?

So, I was at my girlfriend's apartment when I came across a busted tape/cd deck underneath the porch and immediately though "FREE parts!" like any self respecting modder would. The circuit board, in pieces, has been subject to the elements for quite some time, the device made in 2002, I've no idea though how long it has actually been under there.  ("new" place) So two questions. 1) Are any of the components (capacitors, diodes, resistors) safe to use, assuming they were not short circuited by rain/humidity and rust hasn't set in?  (On some parts it has, the motor turning the tape deck being the main and most unfortunate one.) 2) WHAT could I possibly use the sensors/readers that read the tape of the tape deck besides reading the magnetic tape inside cassettes?!  I came to the conclusion that reconstructing a tapedeck with these sensors would be impractical, if not stupid.  Can they sense any magnetic field?  Would it be hard to write an arduino library? I tried looking up a datasheet and get nothing that resembles these, much less something that might belong inside a tape deck. 15RSA0 J2 K1520 Is how it appears on the side of the part, the 0s might be Os.  But the rest is pretty clear (I love a nice font).
