Today's event, part of National Missing Children's Day, will provide parents and caretakers with fingerprints and photo identification that can be used by law enforcement if the child is missing.
Lifetouch National School Studios will be available to take photographs and create identification cards, organizers said.
The event is hosted by the U.S. Parks Police, the Federal Law Enforcement Officers Association, and the Presidio Trust.
No personal information or fingerprints will be retained by law enforcement officials, organizers said.
"The child identification kits are an invaluable tool for law enforcement," U.S. Parks Police Sgt. David Williams in a statement.
"When combined with a Smile Safe Kids ID card from Lifetouch, we can get a child's picture, fingerprints, and other information to agencies across the state and have an Amber alert issued in as little as 15 minutes after a child is first reported missing."
The event will be held between 8 a.m. and 6 p.m. at the Walt Disney Family Museum at 104 Montgomery St. in the Presidio.
The museum will provide educational crafts and activities for kids and participants will receive discounted admission to the museum.
