Product Overview
The HW-6680D is a 2D Bluetooth wireless back-clip barcode scanner engineered for organizations that want professional-grade data capture on the smartphones their teams already use. It mounts directly to the rear of a 5–7 inch handset, turning the phone into a compact scanning terminal without the bulk, cost, and maintenance overhead of a conventional PDA fleet.
Back-clip design for 5–7" smartphones · 1D/2D CMOS scanning on paper and screen · Bluetooth 4.0 + 2.4GHz RF · 3000mAh battery · Optional 860–915MHz UHF RFID reader and pistol grip.
Scanning Engine Built for Mixed Media
At the core is a 752×480 pixel CMOS global shutter sensor. The HW-6680D decodes 1D symbologies — UPC, EAN, Code 128, Code 39, and related formats — alongside 2D QR codes, PDF417, and Data Matrix. Critically, it reads from both printed labels and digital screens, so the same device handles a carton label, a patient wristband printout, and a QR code displayed on a phone or tablet.
Dual Wireless Paths, One Workflow
The connectivity design separates mobile scanning from fixed-station scanning. Bluetooth 4.0 handles pairing to Android and iOS phones and tablets at a range of approximately 20 meters. A 2.4GHz RF dongle shifts the link to a PC or workstation at a range of up to 100 meters, which is useful in receiving bays and packing desks where phone pairing is impractical. Storage mode adds an offline buffer of roughly 10K records at Code128, so scans captured without a live connection can be uploaded later.
Battery Capacity That Changes the Shift Plan
The 3000mAh lithium battery is the specification that separates the HW-6680D from much of the back-clip category, where 1,000–1,200mAh is common. Rated working time is at least 15 hours. In practice, that supports a full shift of intermittent scanning without a mid-day charge — relevant for warehouse cycle counts, courier sorting, and retail stocktaking where charging windows are short and downtime is expensive.
UHF Option: 860–915MHz, 1–27dBm
The platform can be configured with a UHF RFID reader module covering the 860–915MHz band, with RF output adjustable from 1 to 27dBm. This adds tag-based inventory and asset-reading capability to the same phone-mounted scanner, allowing a single deployment to cover both barcode-driven and RFID-driven workflows where required.
Mounting and Ergonomics
The back-clip format keeps the phone's camera and screen accessible during normal use, and the optional pistol grip attaches via a four-screw lock for a more controlled hold during high-frequency scanning. The grip is an optional accessory rather than a fixed part of the body, so the device can be deployed as a compact phone-back unit or a more traditional handheld depending on the task.

Deployment Profile
The HW-6680D is suited to warehouse and logistics operations, medical supply and device tracking, retail shelf and inventory management, and field data collection where a phone-based terminal is preferred over a dedicated PDA. For buyers comparing back-clip barcode scanners, the differentiators concentrate in three places: the 3000mAh battery, the dual Bluetooth/2.4G path, and the optional UHF band at 860–915MHz with adjustable 1–27dBm output.
