1. An indicia reader comprising:
a housing including:
a lower housing portion with a first surface facing a product scanning region, the first surface of the lower housing portion including a horizontal window positioned in a transverse plane; and
an upper housing portion extending above the lower housing portion, the upper housing portion having a second surface facing the product scanning region, the second surface including a upright window positioned in an upright plane;
a first imaging assembly having a first imaging sensor, the first imaging assembly configured to capture first image-data over a first field of view (FOV) extending through the upright window and directed at the product scanning region, the first FOV (FFOV) having a FFOV central axis, a FFOV upper boundary, a FFOV lower boundary, a first FFOV lateral boundary, and a second FFOV lateral boundary, the FFOV lower boundary being closer to the first surface of the lower housing than the FFOV upper boundary when extending over the first surface;
a second imaging assembly having a second imaging sensor, the second imaging assembly configured to capture second image-data over a second FOV extending through the horizontal window and directed at the product scanning region, the second FOV (SFOV) having an SFOV central axis, an SFOV proximal boundary, an SFOV distal boundary, a first SFOV lateral boundary, and a second SFOV lateral boundary, SFOV proximal boundary being closer to the second surface of the upper housing than the SFOV distal boundary when extending in front of the second surface; and
a decoder assembly configured to analyze at least one of the first image-data or the second image-data to decode a payload of an indicia appearing therein,
wherein no other imaging FOV passes through either of the horizontal window and the upright window, and
wherein at least one of:
the first imaging assembly is configured such that a first imaging sensor resolution and a spread angle of the FFOV enable the decoder assembly to decode a 13-mil indicia captured in the first image-data, the 13-mil indicia captured in the first image-data being presented to the FFOV in a first plane that is angled at least 80 degree to the upright plane, the 13-mil indicia captured in the first image-data being oriented such that at least some elements of the 13-mil indicia captured in the first image-data are closer to the upright plane than at least some other elements of the 13-mil indicia captured in the first image-data; or
the second imaging assembly is configured such that a second imaging sensor resolution and a spread angle of the SFOV enable the decoder assembly to decode a 13-mil indicia captured in the second image-data, the 13-mil indicia captured in the second image-data being presented to the SFOV in a second plane that is angled at least 80 degree to the transverse plane, the 13-mil indicia captured in the second image-data being oriented such that at least some elements of the 13-mil indicia captured in the second image-data are closer to the transverse plane than at least some other elements of the 13-mil indicia captured in the second image-data.
