The described mobile device for optically reading a machine- interpretable code, used for example in an order picking system for consumer and/or consumable goods, includes a head-mountable scanner (12) with a code reader (24) and a control unit (42) controlling the head-mounted scanner to switch the code reader between a detection mode and a reading mode. In the detection mode, the code reader operates in a low power mode sufficient to detect the presence of a machine-interpretable code. The control unit switches the code reader into the higher-powered reading mode when the code is detected to optically read the code. A wireless communication device may also be provided to wirelessly transmit information corresponding to the scanned code to a remote receiving unit for storage and/or data processing. |
