Do the CX4438-3627 and CX4440-3629 differ in scan engine capability or supported symbologies?
Both models are specified as 1D/2D camera-based scan engines and both list UPC among supported symbologies. The CX4438-3627 spec explicitly notes '1D/2D barcode symbologies' in its enriched attributes, while the CX4440-3629 similarly lists '1D/2D (UPC, linear codes)' in its enriched data. Neither model's provided specification sheet enumerates a complete symbology decode list beyond UPC. No decode-depth or resolution specification (e.g., minimum element width, scan angle, or motion tolerance rating) is present for either unit. Buyers requiring confirmation of specific symbologies such as PDF417, QR Code, Data Matrix, or GS1 composite codes should request the full decode specification from Socket Mobile before committing to either SKU.
How do the two scanners compare on wireless connectivity, interfaces, and pairing architecture?
Both scanners share an identical connectivity profile as specified: Bluetooth LE as the wireless protocol plus USB as a wired interface. Neither specification discloses the Bluetooth version number (e.g., 4.0, 5.0), Bluetooth profiles supported (HID, SPP, MFi), or USB connector type (Micro-B, USB-C). The CX4438-3627 specification includes a charging dock in the package contents, which has practical implications for multi-shift deployments — the dock provides a defined charging station and cradle for the scanner. The CX4440-3629 specification does not list a charging dock in package contents; no equivalent accessory is noted in the provided data. This is a concrete differentiator for infrastructure planning.
Are there meaningful differences in physical build, weight, or environmental ratings between the two units?
Both models carry an IP67 rating, meaning full dust ingress protection and water immersion resistance to 1 meter for 30 minutes under IEC 60529. Both comply with RoHS standard EN 50581. The CX4440-3629 specification provides a weight value of 0.05 (unit not stated in the provided data — likely kg, equating to approximately 50 g or roughly 1.76 oz), which is an unusually low figure for a handheld barcode scanner and may reflect the scanner body only, excluding dock or battery. No weight figure is provided for the CX4438-3627. No drop-resistance rating, operating temperature range, or humidity specification is present for either model in the provided data, despite 'Storage: Temperature' and 'Battery Life: Information' appearing as placeholder fields in both spec sets.
Which should you choose: the CX4438-3627 or the CX4440-3629?
Our take: The CX4438-3627 is the stronger choice when a bundled charging dock is operationally required at point of sale or shift-change environments, as it is the only model confirmed to include a charging dock in the package contents per the provided specifications. Beyond that single concrete differentiator, the two scanners are specification-equivalent across every other disclosed dimension: both deliver a 1D/2D camera-based scan engine with UPC support, Bluetooth LE and USB connectivity, IP67 dust and water sealing, EN 50581 RoHS compliance, and a one-year warranty. The CX4440-3629 discloses a weight figure (0.05, unit unstated) while the CX4438-3627 does not, which is the only additional data point favoring the CX4440-3629. Buyers whose deployment already includes charging infrastructure or who are cost-optimizing on accessories should evaluate whether the CX4440-3629 meets their needs at a potentially lower bundle price — but that price delta is not confirmed in the provided specs.

Frequently Asked Questions
Which should you choose: the CX4438-3627 or the CX4440-3629?
The CX4438-3627 is the stronger choice when a bundled charging dock is operationally required at point of sale or shift-change environments, as it is the only model confirmed to include a charging dock in the package contents per the provided specifications. Beyond that single concrete differentiator, the two scanners are specification-equivalent across every other disclosed dimension: both deliver a 1D/2D camera-based scan engine with UPC support, Bluetooth LE and USB connectivity, IP67 dust and water sealing, EN 50581 RoHS compliance, and a one-year warranty. The CX4440-3629 discloses a weight figure (0.05, unit unstated) while the CX4438-3627 does not, which is the only additional data point favoring the CX4440-3629. Buyers whose deployment already includes charging infrastructure or who are cost-optimizing on accessories should evaluate whether the CX4440-3629 meets their needs at a potentially lower bundle price — but that price delta is not confirmed in the provided specs.
Is the CX4438-3627 or CX4440-3629 better for a multi-shift retail environment where scanners need overnight charging?
Based on the provided specifications, the CX4438-3627 is the only model confirmed to include a charging dock in its package contents. For multi-shift environments where a dedicated charging station per scanner is required out of the box, the CX4438-3627 has a specification-confirmed advantage. The CX4440-3629 does not list a charging dock in its provided spec data; whether a compatible dock is available separately is not addressed in the specifications provided.
Do both scanners work with standard Bluetooth POS terminals and wireless warehouse management systems?
Both the CX4438-3627 and CX4440-3629 specify Bluetooth LE and USB as their interfaces, and both enriched attribute sets reference compatibility with POS terminals and inventory or warehouse management platforms. However, neither specification discloses the Bluetooth profile (HID, SPP, or MFi) or lists specific certified host systems. Buyers should verify Bluetooth profile compatibility with their specific POS or WMS platform with Socket Mobile before purchase.
Can either scanner read QR codes, Data Matrix, or PDF417 in addition to UPC?
Both scanners are specified as 1D/2D scan engines, which in the industry typically implies support for 2D symbologies such as QR Code, Data Matrix, and PDF417 in addition to linear 1D codes like UPC. However, the provided specifications for both models only explicitly confirm UPC by name. A complete decode list is not included in the spec data provided. Buyers with mandatory 2D symbology requirements should obtain Socket Mobile's full decode specification sheet for each SKU before committing to an order.
