This article provides information about the Elo M60 Pay Mobile Imager Engine / Barcode Reader.

Elo mobile POS uses a sub-miniature imager engine. The sub-miniature area imager engine optimized for bar code reading. The engine captures digital images of a bar code for transmission to a decoder to decode a 1D or 2D bar code of any format supported by the decoding software. The imager engine includes an LED aiming system, and an LED illumination system.

Aiming System
A 610 nm LED is used to generate a circular aiming pattern which indicates the center of the imager’s field of view.

Aiming Error
The aiming pattern is rotated by 2º relative to the imaging axis in the horizontal plane to minimize parallax between the aiming axis and the imaging axis at 195 mm (7.7 in.) from the engine. See Aiming Element below.

Aiming Control
Can capture images with both the aiming subsystem turned on during exposure (the image of the aiming pattern is visible in the digital image) or off. If the aiming system is turned off during exposure, brightness of the aiming pattern decreases as exposure increases. The aiming subsystem can also be turned off completely. Elo recommends shutting aiming off three frames prior to capturing documents to prevent the aiming 

Illumination System
The illumination system consists of one red LED and a sophisticated drive system that allows image capture and decoding throughout a full range of lighting conditions (total darkness to full sunlight).

Illumination Control
The imager engine can capture images with the illumination subsystem turned on or off. LED illumination can be turned off when taking images of documents printed on semi-glossy or glossy paper or on a substrate with security marks. In this case, ensure ambient illumination provides a minimum of 30fcd on the document surface.
