BioUnlock is an upcoming jailbreak tweak that will let you unlock your mac by scanning your index finger on your iPhone 5s’s Touch ID. BioUnlock is developed by Eric Castor who was also behind Mewseek.
The current version will work over WiFi to communicate with your Mac from your iPhone. Eric has mentioned that the bluetooth support is also on the the todo list along with the windows support.
The tweak will cost between $1 to $2 when its released towards the end Jan 2014.

Support for Windows users is planned, but not for the first release.
