Tempus is a time tracking system using an rfid cardreader to allow people to clock in and out. The time stamps can be associated with different projects, there will be some reporting, possible graphs, and most likely other things.

Currently working is a simple Twisted Python application that will read an rfid tag via a Innovations ID-12 (or such) card reader. The rfid value is made available through a websocket as a json structure.

The rfid reader is an Innovations ID-12 available from SparkFun.

Drivers for the rfid reader can be found on the FTDI website.
