FEATURES

Effortless Integration, Faster Development

The low-profile design of MT685 allows seamless integration into space-constrained devices, while the built-in protective window eliminates the need for additional shielding. This streamlined design reduces development time and simplifies assembly, making it ideal for compact scanning solutions in retail, logistics, and access control applications.


Easy and Flexible Operations

MT685 embedded scan engine enhances design flexibility by offering various output interfaces with USB HID, USB VCP, and UART, fulfilling diverse industrial needs of communication methods as well as enabling users to easily configure the reading modes and scanner settings according to preference.


Optimized for Mobile Barcodes

With an enhanced optical design and advanced decoding algorithm, MT685 seamlessly scans all 1D and 2D barcodes on paper labels (matte or glossy), mobile screens, and LCD displays. This capability enables businesses to expand into eCoupons, eTickets, digital IDs, and mobile payment applications with ease.


Bi-directional Communication

A set of commands is supported to enable the host device to configure all the functions of MT685 thereby fulfilling dynamic configurations demand. With multiple interfaces (USB HID, USB VCP, UART) available, MT685 fulfills diverse industrial needs of communication methods as well as enabling users to easily configure the reading modes and scanner settings according to preference.
