Free pcd software for linux

OpenPCD is a free and open RFID reader reference design platform. The OpenPCD firmware is software that runs in OpenPCDs AT91SAM7 ARM controller, and connects the RFID reader hardware (CL RC632 ASIC) with the Host PC via USB. The Firmware includes a custom USB device stack and drivers for the various embedded AT91SAM7 components. The firmware itself does not run on Linux, but it only works with a Linux host PC talking to it.
OpenPCD is a free hardware design for Proximity Coupling Devices (PCD) based on 13,56MHz communication. This device is able to screen informations from Proximity Integrated Circuit Cards (PICC) conforming to vendor-independent standards such as ISO 14443, ISO 15693 as well as proprietary protocols such as Mifare Classic. Contactless cards like these are for example used in the new electronic passports.
The intention of the OpenPCD project is to offer the users full hardware control of the RFID signal and to provide different output signals for screening the communication. With already existing Free Software from the OpenMRTD project for implementing the PCD side protocol stack of various RFID protocols, this project will happily extend the free toolchain around RFID verification.
Enhancements:
- This is the initial version of the firmware.
- It supports basic RFID reader functionality for the ISO14443A.

Kat is an application for KDE designed to index files. Meta information, fulltext and thumbnails are extracted from documents, images, mp3 and other media allowing quick and accurate information retrieval.
Similar to the Windows application WhereIsIt, but also similar to Google Desktop Search, Kat is completely written in C++, using Qt3, KDE and KIO libraries.
The application is based on the extensible kfile plugin architecture of KDE in order to facilitate the creation of new media managers for emerging file formats.
Kat is the first KDE application using the new fulltext kfile plugins.
Information retrieval relies on the powerful SQLite3 embedded database engine.
