Abstract
A data collection device for reading barcodes, matrix codes, acoustical tags, radio frequency identifier (RFID) tags, and other data carriers. The data collection device includes components to determine an actual position of the data collection device with respect to a target data carrier. The data collection device further includes visual indicators to indicate the determined actual position relative to an optimal position of the data collection device relative to the target data carrier. The determined actual position can be at least one of an actual distance or an actual orientation of the data collection device relative to the target data carrier.
