Systems and methods for enabling a picker to correctly identify and pick inventory items from a warehouse or storage facility are provided. An exemplary portable picking-assistance device comprises first and second communication devices. The first communication device is configured to electronically receive a first item list including one or more items to be retrieved by an operator from a predetermined storage area. The one or more items may be selected from a plurality of items stored in the predetermined storage area. The second communication device is configured to communicate radio frequency signals to a first radio frequency (RF) tag of a plurality of RF tags. The first RF tag is associated with a first item listed on the first item list. An indication is provided to the operator confirming an identification of the first item to be retrieved by the operator.
