Description

Technical Field

[0001] This utility model relates to the field of palmprint recognition technology, and more specifically, to a simple palmprint recognition device. Background Technology

[0002] Thanks to the continuous development of electronic information technology, palmprint recognition, as a relatively new biometric identification technology, has gradually entered the public eye.

[0003] Current palmprint recognition devices mostly employ complex mechanical and electronic structures, resulting in a large overall size and weight. This design not only increases the device's footprint but also limits its portability and adaptability to various scenarios. Furthermore, due to the lack of inexpensive and reliable solutions, the hardware design and manufacturing costs of existing palmprint recognition devices are generally high, hindering large-scale market promotion and widespread adoption, particularly limiting their application among small and medium-sized enterprises and individual users.

[0004] The core modules of palmprint recognition devices (camera and processing chip) are prone to generating high temperatures during long-term operation. However, in order to save internal space, many existing devices do not adequately consider heat dissipation in their design, relying solely on natural convection for cooling, resulting in low heat dissipation efficiency. This heat accumulation not only affects the operational stability of the device but may also accelerate the aging of electronic components, shorten the device's lifespan, and thus increase maintenance and replacement costs.
