If you’ve done a more expensive one, I’d like to hear it!

Today I had to get to the center of Geneva from the airport, and in a bit of a hurry as the meeting I had to attend was getting close. I decided to take a taxi, which would also allow me to do a quick wardrive using my Qtek and a Bluetooth GPS. Finding almost 80 WiFi access points on the way was great, but the bill was painful! In all, the round trip from and back to the airport cost me 60 euros, some quick math makes each AP cost 75 cents (around $0.96).

Tomorrow, I will post some stats and a quick map of the captured APs. The stats will of course go to WiGLE, and the map will be made using an updated version of StumbVerter I’m working on – this will use MapPoint as usual, but you will also have the option of creating maps in Google Earth format. However, they will not look like the usual 2D icon maps that can be made using existing scripts, but will feature the traditional Netstumbler towers in 3D. How to show the signal strenght is being worked on, any suggestions?

RFID, which stands for Radio Frequency Identification, is ubiquitous in our lives. We find RFID tags in our library books, grocery, consumer goods, printer cartridges, and are even implanted into people’s bodies.

The basic principle behind RFID is that a simple, passive device responds to a burst of RF with a unique number, which can be used to identify the object to which the device is attached. There are many types of tags, some of them can even be written to. When I have the time, I will write an in-depth article on this subject.

RenderMan, Thorn and Audit have written a book on this topic, titled RFID Security. You can get this book at Amazon.com. RenderMan is very active in the Church of WiFi, Thorn has participated in other books, such as Wardriving: Drive, Detect, Defend. Audit is a very active moderator of the Netstumbler forums, hosts personalwireless.org, and also participates in many WiFi-related projects.
