Palm print recognition camera module, small body big role
In recent years, "palm print payment" continues to be hot, Tencent and Alipay two payment giants have launched "brush palm payment" function and terminal, and fast market, brush palm payment has been widely landed in the Daxue canteen, large stadiums, concert venues, convenience stores, Railway metro lines, such as brush the palm of the metro line through the gate ride and other industry scenarios.
How are palm prints recognised?
From the technical principle, the core logic of palm print recognition is the same as face recognition and fingerprint recognition, which all make use of the uniqueness of certain aspects of the human body. No matter how similar a person's face looks, there will always be slight differences in structure. The same is true for palm prints, which are made up of thousands of lines randomly arranged and combined, which constitutes the uniqueness and uniqueness of palm prints.
Palmprint recognition technology first uses image sensors to capture palm lines, then preprocesses the image according to an algorithm to extract the characteristics of the palm lines, and then establishes a palmprint database. When the user is brushing the palm print, the current palm print will be compared with the data in the database to achieve accurate recognition. In order to ensure that palm print payment is safe enough, palm vein recognition is also added to achieve a double guarantee of security.
From the perspective of specific technical details, the core of palm print recognition products are AI algorithms and perception chips. At present, these two technologies are mature in China.
From the perception chip point of view, whether it is palm print recognition, fingerprint recognition or face recognition, the core sensors required are CIS chips and camera modules.
Palmprint recognition can be used in the payment field, but also in what areas:

Palmprint recognition can be used in the payment field, but also in what areas:
- Security access control system: for the management of access rights in restricted areas.
- Financial transaction equipment: to enhance the security of financial transactions.
- Smart phones: Provide convenient identity verification.
- Computer login system: to increase the security of login.
- Public facility entrances: such as airports and underground stations.
- Government agencies and military facilities: Ensure highly secure access control.
- High resolution: able to clearly capture palm print details.
- Wide viewing angle: to cover a sufficient area of the palm print.
- High-quality images: reduce image blurring and noise.
- Fast response: Capture palmprint images in real time.
- Ability to work in different lighting conditions: Adapts to a variety of ambient lighting.
- Miniaturisation: for easy integration into devices.
- Low cost: to enable a wide range of applications.
- Reliability and stability: to ensure long-term stable operation.
