With high-tech guns, users could disable remotely

A high-tech startup is wading into the gun control debate with a cellphone controller that would allow gun owners to know when their weapon is being moved—and disable it remotely.

There's no actual gun yet, but the technology from Yardarm Technologies LLC comes at a time when lawmakers around the U.S. are considering contentious smart gun laws that would require new guns to include high-tech devices that limit who can fire them.

The Yardarm system would add about $50 to the cost of a gun, and about $12 a year for the service.

The National Rifle Association says it is concerned about added costs and the reliability of smart guns in general. Officials at the organization said they weren't familiar with Yardarm.
