Abstract

A barcode reader and a docking station for charging the barcode reader are disclosed. The barcode reader may be an elongated pen-shaped device that includes a capacitive tip for use as a stylus against a capacitive touch screen and a barcode reader for reading a barcode. The barcode reader may be docked in the docking station for charging. The docking station may include a magnetic structure for holding the barcode reader to the docking station, and a positioning structure for aligning the charging contacts of the barcode reader and the docking station. The docking station may include a battery such that the barcode reader may be charged from the battery while being docked in the docking station.
