1. A computer-implemented method, comprising:
- instructing a mobile drive unit to move a holder to a first position relative a reading structure, the holder detachably coupled to the mobile drive unit and including a plurality of items stowed in the holder;
initiating an antenna attached to the reading structure;
reading, via the antenna, a first identifying tag associated with a first item when the mobile drive unit and the holder are located at the first position, the first item stowed in the holder;
responsive to reading the first identifying tag, instructing the mobile drive unit to move the holder to a second position relative to the antenna; and
reading, via the antenna, a second identifying tag associated with a second item when the mobile drive unit and the holder are located at the second position, the second item stowed in the holder.

Abstract
In some examples, a reader system is provided for managing inventory items in an inventory system. The reader system may be configured to read tags associated with items stowed in an inventory holder. The inventory holder may be detachably coupled to a mobile drive unit. The mobile drive unit may move the inventory holder to a first position near an antenna of the reader system and the tags may begin to be read. While reading or at other times in the reading process, the mobile drive unit may move the inventory holder relative to the antenna. The identified tags may be compared to a manifest list of items expected to be stowed in the inventory holder.
