Two laser tools make moves on foodservice. I n school cafeterias where students normally must present their meal-plan ID cards, backups and lines are common.
Bar codes allow products to be quickly identified and moved.
It would help if people came equipped with such individualized codes. As it happens, they do. Operations such as the University of Georgia in Athens keep lines moving by identifying students with high-tech equipment that scans their palms. In the 1970s, the university began searching for alternatives to ID cards, which can be misplaced or misused, says J. Michael Floyd, who heads its foodservice department. Additionally, college students are prone to change their appearance frequently and sometimes radically.
