MT682 2D Scan Engine

Wide Angle Optics for Contact Scanning

MT682 is a 2D scan engine designed to scan mobile barcode in the easiest way. MT682 has a compact enclosure with an extra wide angle optics for contact scanning and captures all major 1D and 2D barcodes on mobile display. Its ready-to-use design accelerates the developing of mobile barcode scanning platform.

Omnidirectional, Snappy Scanning

Built with highly sensitive image sensor, MT682 not only automatically captures any moving barcode at close range, but also delivers omnidirectional scanning in any direction, eliminating the need to align barcode. As a result lines are kept moving and wait time is minimized.

Largest Field of View

With the largest field of view, 62° horizontal degrees and 48° of vertical degrees of wide scan angle, MT682 is capable of scanning the widest barcode from 10mm to 100mm away. As a result MT682 is suitable to be integrated into device with very limited reading distance in a constraint space.

Mobile-Friendly Scanning

With enhanced optical design and latest decode algorithm, MT682 virtually scans all 1D and 2D barcodes printed on any surface, either paper-based label with matte or glossy surface, or mobile phone display and LCD screen. As a result users may expand their business into many new applications such as eCoupon, eTicket, Digital ID cards and mobile payments.
