Socket Mobile SocketScan S720 | Bluetooth 1D/2D Barcode Scanner + Charging Dock | Apple MFi | Auto Scan Mode | Blue + Black Dock
Overview
The Socket Mobile SocketScan S720 Blue + Black Dock kit (CX3985-3042) bundles the S720 Bluetooth 1D/2D barcode scanner with a dedicated charging dock — creating a complete mobile scanning station out of the box. The scanner reads all popular 1D and 2D barcode types, including QR codes, DataMatrix, and PDF417, from printed labels and mobile screens. It is Apple MFi certified and integrates natively into over 700 applications via Socket Mobile's CaptureSDK.
The included charging dock adds important functionality beyond simple charging:
- Auto Scan (presentation) mode — when the scanner is placed in the dock, it automatically switches to hands-free continuous scanning, decoding any barcode brought within range without pressing the trigger
- Always-charged — dock it when not scanning; the scanner is always at full charge when picked up for mobile use
- Fixed scanning station — mount the dock on a counter for a dedicated scanning position while keeping the option to detach for handheld use

Use Cases
Retail Counter Station: Mount the dock on the checkout counter — scanner sits in Auto Scan mode for hands-free loyalty card and product scanning. When a cashier needs to scan a large item, they pick up the scanner for handheld use and return it to the dock when done.
Hospitality & Events: Blue high-visibility colour makes the scanner easy to locate. Dock at the desk when not in use; pick up for ticket scanning, check-in, or tableside ordering.
Mobile POS with Fixed Base: iPhone/iPad mPOS setups where the scanner needs to work both as a handheld and as a fixed station. The dock handles both roles.
Asset Tracking & Delivery: 16-hour battery with dock charging means the scanner is always ready at shift start — charge overnight in dock, scan all day in the field.
Frequently Asked Questions
What does the charging dock add vs just the scanner alone?
The dock has two functions: it charges the scanner when placed in it, and it activates Auto Scan (presentation) mode — the scanner continuously reads any barcode presented within range without pressing the trigger. This turns the S720 into a hands-free counter scanner. Without the dock, the scanner charges via USB cable only and Auto Scan mode can be configured via software.
Can the dock be used with other S720 colour variants?
Yes. The charging dock is compatible with all S720 variants regardless of colour — it is not colour-specific. If you already have a scanner from another S720 kit, the dock can be purchased separately as Socket Mobile accessory AC4064-1498 (charging stand/dock).
Does the S720 Blue work with the same apps as the other S720 colours?
Yes, completely identical. All S720 variants share the same scanning engine, Bluetooth implementation, and CaptureSDK integration — colour is purely cosmetic. Any app that works with the Black S720 will work identically with the Blue variant.
Is there a white dock version available?
Yes. The CX3991-3048 variant provides the same Blue S720 scanner with a White charging dock — suitable for environments where the black dock does not match the counter aesthetic (e.g., Apple retail-style environments or white POS setups).
