H4E series of compact finger vein authentication modules utilize vein patterns in fingers and achieve biometric authentication
with lower risk of forgery and less influence on privacy.
A compact module with a system to irradiate light beams from right and left onto the finger and capture a finger vein image. Support for outdoor use is enhanced, and authentication accuracy and usability are drastically enhanced, thus offering "empty-handed" authentication.

(Play the video to hear the "beep" sound indicating authentication.)
This function handles differences in finger vein patterns at authentication from the those at the time of registration due to finger placement and temperature changes, reducing authentication errors.
When an authentication error occurs due to a misaligned scanning position, the continuous authentication function performs minor adjustments to finger placement in real-time, reducing authentication errors.
This function detects dirt on the sensor and urges the user to clean it so that the module may be used outdoors with high reliability.
A three-colored LED indicator and beep sound have been added as a status notification function to indicate whether the finger has been correctly placed.
Through an enlarged scanning area and improved authentication algorithms, authentication accuracy has been improved by roughly 10 times* compared with previous models, offering enhanced security.
*For detailed specifications, refer to Specification Table No. 14 below.
With improved IP rating dust- and water-proofing, an expanded temperature range, and an outside light mode that facilitates authentication in environments with external light such as outdoors, the new specifications are suited to outdoor use.
*For detailed specifications, refer to Specification Tables Nos. 19 to 24 below.
Batteries can be used by reducing required power (in authentication/stand-by mode*) and widening operating supply voltage range*.
*For detailed specifications, refer to Specification Tables Nos. 5 to 7 below.
To conform to the new normal, the module features an antibacterial coating* that allows regular sterilization with alcohol.
*Antibacterial coating: Compliant with JIS Z2801 5.2/ISO 22196.
The modules, when incorporated in existing products in various fields, enhance security and convenience.
Application examples are provided below.
The module can be used in place of a lock of the front door of a house or apartment and ensuring safety and convenience.
When attached to shop or office entranceways where a number of people have keys, the modules replace the locks to prevent lost or forgotten keys. This requires no key duty and avoids unauthorized duplication, thus eliminating burden on management and enhancing security.
IC cards may frequently be forgotten, go missing, or be faked.
Reliable personal authentication can prevent impersonation and reduce running costs, since IC cards are no longer necessary.
When a number of people frequently use a safe for storage, use records can be precisely managed. Even when it is not used for a long time, there is no concern about a lost key or forgotten PIN.
The modules may be used as a control switch of a device in a factory and set to allow access only by permitted operators. When incorporated into the work record management system of the equipment or warehouses, they can also be used for confidentiality control.
The modules can be used to ensure security of equipment connected via Internet or related devices, thus preventing loss of access due to forgetfulness, going missing, and impersonation and ensuring safety, security, and convenience.
