Abstract
A system may include a first security component configured to emanate a signal with an authorizing code, and may have a magnetic field generating device configured to generate a signaling magnetic field including the signal with the authorizing code. The system may also include a second security component configured to wirelessly receive the signal with the authoring code when the second security component is proximate to the signaling magnetic field of the first security component. The second security component may include a magnetic field sensor configured to sense the signal emanating from the magnetic field generating device, and the sensor may be changed between first and second states by a change in the signaling magnetic field.
