22C3 is fun as long as you are inside BCC because its freezing cold here in Berlin. There are plenty talks and this time I managed to go to three talks on the first day. 1) Hacking Data Rentetion, which I didn't like too much for multiple reasons. 2) Die Technik im ePass, this was very interesting and well presented. 3) RFID - overview of protocols etc.., also very interesting but too much information in the short time.
