Democrats are looking to place new restrictions on who can use handguns.
The Handgun Trigger Safety Act introduced Tuesday by Sen. Edward Markey (D-Mass.) and Rep. Carolyn Maloney (D-N.Y.) aims to block criminals and children from using guns that do not belong to them.
Gun dealers would be required to install smart gun technology that fires only if it recognizes the shooter, such as the person who purchased the gun or someone they designate as an authorized user.
Some smart gun technologies use fingerprints, while others require the shooter to wear a bluetooth bracelet or receive a microchip implant that unlocks the gun.
