Mobile phones have become ubiquitous and basic communications tools—now used not only for phone calls, but also for accessing the Internet, sending text messages, and documenting the world.

This could be used to investigate a crime, or to find out who was present at a particular protest.

Both of these kinds of wireless signals include a unique serial number for the device, called a MAC address, which can be seen by anybody who can receive the signal.

The device manufacturer chooses this address at the time the device is created and it cannot be changed using the software that comes with current smartphones.
