MT84G 2D Mini Scan Engine

Ideal for Space-Constrained Applications

MT84G is an extremely miniaturized 2D scan engine that is designed to fit into the most space-constrained applications including mobile device, wearable device and smartphone. With 3.3V low voltage power supply and power consumption of a few micro amps during sleep mode, MT84G barcode scan engine is also ideal for host device with limited battery.

The Smallest in the Industry

MT84G scan engine is by far the smallest 2D barcode scan engine in the AIDC industry. With extraordinarily small size of W14 x L9.5 x H9.3 mm and the weight of less than 1 gram, MT84G can fit into the most space-constrained products, providing unparalleled flexibility for product design.

Mobile-Friendly Scanning

MT84G, with enhanced optical design and latest decode algorithm, virtually scans all 2D barcodes on any surface, either paper-based label or mobile phone display. With MT84G scan engine integrated into mobile device, users may expand their business into many new applications such as eCoupon, eTicket, Digital ID cards and mobile payments.

Reliable and Flexible Operations

With golden fingers for connection, MT84G scan engine can be firmly mounted on the host PCB with soldering, which not only increases mechanical reliability but reduces cost and risk incurred in installing flex cable and connector. The flash memory of MT84G serves as a flexible and upgradeable provision for additional requirements or performance enhancement and extends the product's lifecycle as well.

Ambient Light Immunity

MT84G scan engine automatically adjusts its parameters for optimal scanning performance which provides the freedom to scan barcodes from under complete darkness to direct sunlight. With configurable scan rate between auto-adaptive mode and fixed mode, MT84G is ideal for both high-speed scanning applications and smart devices which require more motion tolerance and ambient light immunity.

Useful Demo Kit

MB100 Demo Kit (sold separately) provides the software and hardware tools required for testing MT84G before integrating it into the host device. The kit contains software utility, interface cables and MB100 Multi I/O board. Due to its small size, MB100 is also suitable for being installed inside the host system as an interface board connecting MT84G scan engine to the host device.
