Data Capture 4 - 5
Imaging
MC9500-K with an integrated imager have the following features:
•
Omnidirectional (360°) reading of a variety of bar code symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
•
The ability to capture and download images to a host for a variety of imaging applications.
•
Advanced intuitive laser aiming for easy point-and-shoot operation.
The imager uses digital camera technology to take a digital picture of a bar code, stores the resulting image in its
memory, and executes state-of-the-art software decoding algorithms to extract the data from the image.
