Using the Scan Image Engine
Overview
The Dolphin 75e terminal houses a compact image engine that instantly reads popular 1D and 2D bar codes and supports
omni-directional aiming and decoding for greater flexibility in real-world settings. The image engine can also capture black and
white digital images, such as signatures and pictures of damaged inventory.
With the latest CMOS-based technology, the engine works like a digital camera and enables black and white digital image
capture, signature capture, and reading of OCR characters.
