Since October 2024, the CBM-E4 has officially succeeded the MorphoSmart CBM V3 / E3 modules. This new version, offered by IDEMIA, maintains the form factor and performance of the previous models while introducing notable technical improvements. This change directly affects OEM integrators and end users looking to ensure service continuity and optimized software compatibility.

A biometric sensor that preserves the fundamentals of the CBM V3 / E3

The MorphoSmart CBM E4 module retains the mechanical dimensions and functional architecture of the CBM V3 / E3 range, thereby facilitating the transition for integrators. It remains a 500 dpi optical sensor designed for reliable fingerprint capture in demanding environments.

Biometric performance remains consistent: recognition rate, acquisition speed, and authentication accuracy are comparable to the previous generation. The module still relies on the proven technology used in MSO devices, while introducing a significant upgrade in embedded security.

A discreet but strategic technical upgrade for OEM integrators

The CBM-E4 introduces several changes that require careful consideration during integration:

• LED positioning: now placed on the sides instead of the top of the module.
• Diffuser removed: which may affect aesthetic integration into certain enclosures.
• New PID/VID configuration: driver updates are required, along with the use of MSO SDK version 6.49.1 or higher.

A “Legacy_USB_ID” version is available to maintain compatibility with previous PID/VID values (E3), but no backward compatibility with E2 versions is planned. The module also implements enhanced security algorithms (AES256, SHA-2), with configuration now handled via the SDK instead of the MKMS tool.

A structured transition for CBM V3 / E3 users

The end-of-life schedule for the CBM V3 / E3 modules is clear:

• Last order date: January 30, 2025
• Last shipment date: March 31, 2025
• End of technical support: March 31, 2027

For ongoing or maintenance projects, it is recommended to switch to the CBM-E4 version now to benefit from the latest updates and ensure compatibility with future software developments. The module remains suitable for a wide range of applications: access control, embedded terminals, identification kiosks, and secure mobile devices.

Migration to the CBM-E4 thus allows OEM integrators to preserve their existing architecture while ensuring the longevity of their biometric solutions.
