The MS120-A Bar Code Wand is targeted towards low reading volume and cost effective solutions. The advanced optics and electronic design converts Bar Code labels into a high quality digital signal. Able to read color, faded and low contrast Bar Codes quickly and accurately, the MS120-A is a proven solution. Its shape gives the MS120-A the comfort and handling of a normal ink pen. Just sweep the tip of the wand across the bar code in either direction and listen for the "good read" beep that lets you know the data has been successfully captured. It doesn't get any easier than that.
