1. A method for actuating a perforating gun in a wellbore, comprising the steps of:

  • (a) providing a first downhole structure that comprises a non-acoustic identification transmitter unit that stores an identification code and transmits a non-acoustic signal corresponding to the identification code;

    (b) providing a perforating gun having a non-acoustic receiver unit that can receive the signal transmitted by the identification transmitter unit, decode the signal to determine the identification code corresponding thereto, and compare the identification code to a preset target identification code;

    (c) lowering the perforating gun in close enough proximity to the first downhole structure so that the non-acoustic receiver unit can receive the non-acoustic signal transmitted by the non-acoustic identification transmitter unit;

    (d) comparing the identification code determined by the non-acoustic receiver unit to the target identification code; and

    (e) if the determined identification code matches the target identification code, the perforating gun is fired.
