There are a number of choices available to firms seeking support for their order picking operations. Solutions such as RF scanning, pick to light, and paper picking are used by many firms; but none allow workers to do what they can with a voice-directed solution: pick with optimal levels of productivity and accuracy. Following are some comparisons of the various systems that will be helpful in evaluating voice picking.
RF scanning directed picking achieves neither optimal speed nor accuracy. While holding an RF scanning device, pickers have only one hand free. To free their hands to make a pick, workers have to waste time putting the device down and then picking it up again. Some workers try to continue to hold or balance the device against their body as they make the pick. This makes them are more prone to drop and damage the product and or the device.
