This comes after the school massacre in Newtown, Connecticut, last month.
The SouthtownStar reports that Frankfort School District 157-C will scan visitors' driver's licenses and do a background check right away beginning Tuesday.
If there is a threat, the system will alert officials.
Doors to all district schools will now be locked and visitors will be buzzed in.
To get a head start, parent organization volunteers can have their IDs scanned into the system Friday, from 1 to 3 p.m at the district office.
