EDISON - German company Armatix says it has come up with ways to ensure only a designated user can fire a gun.

The company claims it has created the first gun equipped with a user recognition system - a so-called smart gun. The technology will only allow the gun to fire when it is within range of a wristwatch transmitting a signal.

A law was passed in New Jersey 10 years ago stating that all guns sold in the state would need to have this technology attached as soon as the technology is available. The law cannot take effect until three years after the smart guns are readily available.

Firearms advocate Latief Dickerson says there is nothing safe or smart about the newly designed feature. Dickerson says the more technology you put on something the more that can go wrong.

Armatix says it will introduce the smart gun technology within the next 45 days.
