Fujitsu demonstrates a high-speed checkout scan tunnel developed as a prototype for Kroger grocery stores. The tunnel has 12 cameras that scan barcodes from any direction, including below the high-speed belt. Kroger has tested the device at a store in Ohio, calling it "Advantage Checkout." The device is said to match the throughput of two to three conventional checkout lines. Customers can quickly dump items on the belt (without careful placement) and then complete the transaction in self-service fashion.
