A bill that mandates antitheft technology to come pre-installed on all smartphones sold in California is headed to the governor after passing a final California Senate vote on Monday.

The bill, introduced by state Sen. Mark Leno and sponsored by San Francisco District Attorney George Gascon, asks that device makers put so-called "kill-switch" technology on every smartphone, though users could choose to opt-out of the security services. The software lets users lock the phone if it is stolen, making it inoperable.

The bill passed with a 27 to 8 vote.

The proposed legislation, formally named SB962, addresses what government officials have called an "epidemic." One in 10 smartphone owners in the US has had a phone stolen, according to the mobile security firm Lookout. In 2013, more than 3 million Americans were the victims of smartphone theft -- nearly twice as many as the year before, according to Consumer Reports. On Gascon's home turf of San Francisco, more than 65 percent of robberies in 2013 involved a mobile device. The rate jumps up to more than 75 percent across the bay in Oakland.

"Our goal is to swiftly take the wind out of the sails of thieves who have made the theft of smartphones one of the most prevalent street crimes in California's biggest cities," said Leno, in a statement.

The kill-switch bill passed the California State Assembly last week. Introduced during a press conference in February by Leno and Gascon, the bill narrowly failed its first vote in the state Senate in April, but passed two weeks later in early May.
