Socket Mobile CX4238-3326 vs Socket Mobile CX3982-3039: Specification Comparison
Both the Socket Mobile CX4238-3326 (SocketScan S320) and CX3982-3039 (SocketScan S720) are handheld, Bluetooth-wireless 2D barcode scanners from the same manufacturer, positioned for mobile retail, inventory, and field use. Both pair wirelessly with iOS and Android devices and share a one-year warranty. This comparison evaluates where the two models diverge across symbology breadth, platform compatibility, and specialized features to help buyers select the right scanner for their deployment environment.

Which scanner reads a broader range of barcode types?
The CX4238-3326 (S320) explicitly lists five confirmed symbologies across both 1D and 2D tiers: Code 128, Code 39 (1D), and QR Code, Data Matrix, and PDF417 (2D). This makes it well-suited for environments requiring Data Matrix codes — common in healthcare, electronics, and industrial part tracking — as well as PDF417, used on government IDs, boarding passes, and shipping labels.
The CX3982-3039 (S720) lists QR Code (2D) and UPC (1D) in its structured specs. Supplemental descriptions mention Code 128 and EAN as additional symbologies, but these do not appear in the verified spec fields. Buyers who depend on Code 128, EAN, Data Matrix, or PDF417 should note that these are not confirmed in the S720's structured specification data. If those symbologies are mission-critical, the S320 provides explicit confirmation.
Which platforms and pairing protocols does each scanner support?
The CX4238-3326 (S320) specifies compatibility with iOS, Android, and Windows, supporting both Bluetooth HID and SPP profiles. The HID profile allows keyboard-emulation input with no custom drivers required, while SPP (Serial Port Profile) enables deeper integration with custom applications. The 50-foot Bluetooth range is explicitly stated in the supplemental data.
The CX3982-3039 (S720) specifies iOS and Android compatibility. Windows is not listed in any spec field for this model. The data output methods noted are keyboard emulation and standard serial protocols, which aligns with HID and SPP functionality, but Bluetooth profiles are not explicitly named. The wireless range is not specified for the S720. Deployments requiring Windows workstation pairing should rely on the S320's confirmed Windows support rather than assuming S720 compatibility.
What differentiating features and operating conditions separate these two models?
The CX4238-3326 (S320) includes an Integrated Secure Pad, described as enabling on-device PIN entry and cryptographic transaction signing. This is a meaningful differentiator for payments, age verification, or any workflow requiring authenticated input at the point of scan. Operating temperature is explicitly documented: 0° to 45°C (32° to 113°F), covering standard indoor commercial environments.
The CX3982-3039 (S720) carries no equivalent secure input feature in its specifications. No operating temperature range is provided for this model. The S720's supplemental description emphasizes ergonomic comfort for high-volume inventory sessions, and its compact white handheld form factor is noted, but no quantified environmental or physical durability ratings are present in the available spec data. Buyers operating in known temperature ranges or requiring secure transaction capability cannot confirm S720 suitability from the provided specifications.
Which should you choose: the CX4238-3326 or the CX3982-3039?
Our take: The CX4238-3326 (S320) is the stronger choice when breadth of symbology support, Windows compatibility, or secure transaction capability is required. On symbologies, the S320 confirms five types including Data Matrix and PDF417 versus two confirmed types (QR Code, UPC) for the S720. On platform reach, the S320 explicitly adds Windows to iOS and Android, while the S720 lists only iOS and Android. The S320 also provides a stated 50-foot Bluetooth range and a documented operating range of 0°–45°C, neither of which is confirmed for the S720. Additionally, the S320's Integrated Secure Pad has no equivalent in the S720 specs. The CX3982-3039 (S720) may suit simpler iOS/Android QR and UPC workflows where ergonomic comfort during high-volume scanning is the primary concern, but its spec record leaves several common evaluation criteria unanswered.

Additionally, the S320's Integrated Secure Pad has no equivalent in the S720 specs. The CX3982-3039 (S720) may suit simpler iOS/Android QR and UPC workflows where ergonomic comfort during high-volume scanning is the primary concern, but its spec record leaves several common evaluation criteria unanswered.
Is the CX4238-3326 or CX3982-3039 compatible with Windows POS systems?
Only the CX4238-3326 (S320) explicitly lists Windows as a supported platform alongside iOS and Android. The CX3982-3039 (S720) specifies iOS and Android only — Windows compatibility is not confirmed in its available specifications.
Can either scanner read Data Matrix or PDF417 codes used in healthcare or shipping labels?
The CX4238-3326 (S320) explicitly confirms Data Matrix and PDF417 in its verified symbology list. The CX3982-3039 (S720) does not list Data Matrix or PDF417 in its structured specs; those symbologies are absent from its confirmed specification data.
Does either scanner support secure PIN entry for payment or age-verification workflows?
Yes — the CX4238-3326 (S320) includes an Integrated Secure Pad for on-device PIN entry and cryptographic transaction signing, as stated in its specifications. The CX3982-3039 (S720) has no equivalent secure input feature listed in its available spec data.
