Hi Eddie! I have no first-hand experience, but I wonder if . . . You could limit the size of the items to be scanned so that the laser scanner could be mounted -- facing down -- about 4" or 6" above a counter, not leaving enough room for a child to (a) squish their head underneath or (b) have a direct line of sight at the laser? Other thoughts? Best wishes, sincerely, Jay Heuman Visitor & Volunteer Services Coordinator Joslyn Art Museum 2200 Dodge Street, Omaha, NE, 68102 342-3300 (telephone) 342-2376 (fax) "You can’t lock up art in a vault and keep it frozen for posterity.

In our discussions with staff we have some with concerns about using actual laser scanners because of an eye safety issue. Some feel if children look at the scanner laser light it may cause eye damage. I have been to a couple of museums that use scanners in the Grocery Store exhibits. How have other museums addressed this issue? Thanks, Eddie Lott Director of Education and Exhibits The Children's Museum of South Carolina 843-946-9469 [log in to unmask]
