Niesha looked up at the eager young girl, and smiled, "A jammer works at jamming things like cameras, alarms, things like that. If I could steal the alarm code, I would, but somethings that has a trigger in on itself. The jammer makes it so I can't be seen, I can get in and out easily without fear of being caught, or of leaving digital footprints of myself running around so the cops can find me. The trouble with some alarms is that the company will send out the cops, so this is the safest option"

She smiled, "You give me anything to do with technology, I can build it, take it apart, make it better"
