don't we already do this?
The National Instant Criminal Background Check System, or NICS, is all about saving lives and protecting people from harm—by not letting guns and explosives fall into the wrong hands. It also ensures the timely transfer of firearms to eligible gun buyers.
Mandated by the Brady Handgun Violence Prevention Act of 1993 and launched by the FBI on November 30, 1998, NICS is used by Federal Firearms Licensees (FFLs) to instantly determine whether a prospective buyer is eligible to buy firearms or explosives. Before ringing up the sale, cashiers call in a check to the FBI or to other designated agencies to ensure that each customer does not have a criminal record or isn’t otherwise ineligible to make a purchase. More than 100 million such checks have been made in the last decade, leading to more than 700,000 denials.http://www.fbi.gov/about-us/cjis/nics

How can I walk into a gun shop, which I have, and be gone in 10 minutes if they do a background check?
