Using the Scan Image Engine
Overview
The Dolphin 70e Black 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.
