Kroger was the first retail chain to develop automated tunnel scanning. It did so in its labs and then tested the technology on a sales floor at its store in Hebron, Ohio, last spring. The tunnel uses optics and conveyers moving twice as fast as current belts, scans double the number of products in the same period and obviates manpower. The company is now negotiating with Fujitsu to refine the tunnel and then mass-produce it.
