If you have the need to read the data from an 125 kHz RFID from a short distance, then the project published by security consultants Bishop Fox may be of interest. They've demonstrated how to make a device that can read the cards using a commercial RFID reader commonly found in fixed, in-building installations (which is instead mounted in a briefcase) and then connected to an Arduino to receive the card data and write it to an SD card for later analysis.
The purpose for such a project is to demonstrate the weaknesses of RFID systems, and how simple it is to create your own snooping devices. For more information including the required hardware and Arduino sketch, check out the Bishop Fox website. You might also find this article of interest. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you're looking for a fast way to interface RFID readers with your Arduino or compatible board, check out our new DLOCK RFID Door Lock Shield. It's a fantastic and simple method of interfacing a variety of RFID readers and an electric door strike to your Arduino-compatible board. The design is based on the circuit described in the "RFID Access Control System" project in the book "Practical Arduino", and the shield arrives in assembled form to save time and effort:
With the DLOCK shield you can easily interface common RFID readers such as ID12, ID20, RDM630, RDM880 and HF MultiTag readers. Furthermore there's status LEDs, power jumpers for door strike power and plenty of space for extra on-shield circuitry. For more information and to order, please visit the DLOCK page.
