Introduce the rejection rate and false acceptance rate of the fingerprint

-

 With the popularity of Fingerprint Scanner equipment, we often encounter various problems when purchasing Fingerprint Scanner equipment, such as some professional terms about Fingerprint Recognition Time Attendance equipment that we cannot understand, such as what is fingerprint identification? rate and false recognition rate, the following Fingerprint Recognition Time Attendance manufacturers will introduce what is the false rejection rate and false recognition rate of fingerprints.

Fingerprint Scanner

To put it simply, the false rejection rate of Fingerprint Scanner with fingerprint head recognition is the same fingerprint, which is recognized as different by the algorithm; the false recognition rate of Fingerprint Recognition Time Attendance fingerprint recognition is different fingerprints, which are recognized as the same by the algorithm.
The Fingerprint Scanner has the rejection rate and false recognition rate of fingerprint recognition, which can also be called the rejection rate and false recognition rate. The rejection rate is FRR, which means that the real fingerprint image will be recognized as fake. The false recognition rate is FAR, which means that a fake fingerprint image is recognized as real. The rate of rejection and false recognition of fingerprint heads affecting Fingerprint Recognition Time Attendance tools is related to the resolution of the collection window of fingerprint heads and the method of obtaining fingerprints in fingerprint identification technology.
The rejection rate and false recognition rate of Fingerprint Scanner are important goals for identifying the quality of Fingerprint Recognition Time Attendance tools. The rejection rate and false recognition rate of Fingerprint Recognition Time Attendance directly affect Fingerprint Recognition Time Attendance. The response time of the tool and the accuracy of fingerprint identification will affect the user experience and the security performance of the Fingerprint Recognition Time Attendance tool.
At present, the resolution of fingerprint heads on the market is above 500DPI, that is, there are 500 pixels per inch, that is, theoretically, there can be 500 information points in the fingerprint image per inch for comparison and identification.
Previously, the Ministry of Public Security issued the standard of rejection rate and false recognition rate: the rejection rate should be =<3%, and the false recognition rate=<0.001%. According to the relevant regulations, the security level of Fingerprint Recognition Time Attendance tools for household entry doors should be level 3, that is, the rejection rate < 0.1%, and the false recognition rate = < 0.001%. Many Fingerprint Scanner brands advertise that the resolution of the fingerprint head used is roughly within this range. The specific indicators may vary, but as long as it is a brand manufacturer's product, the user experience will not be far behind.
There is a trade-off relationship between "rejection rate and false recognition rate". Fingerprint Scanner and fingerprint recognition are at the same level. The higher the rejection rate, the lower the false recognition rate, and vice versa. This is an inverse relationship. However, if the level of technology and technology is improved, these two indicators can be lowered, and the level of technology still needs to be improved in essence.

  Recently, the team from Chongqing Huifan Technology Co., Ltd.—a biometric technology enterprise operating under the international brand "HFSecurity"—arrived in Ghana immediately after attending the ID4Africa 2026 exhibition in Abidjan, Côte d'Ivoire. Without missing a beat, they embarked on a series of in-depth client visits and on-site project surveys, thereby fulfilling their market commitment to "take root in Africa and serve local communities" through concrete action. During their time in Ghana, the team visited numerous financial institutions, educational establishments, and partners involved in identity registration projects. At bank counters, real-name authentication terminals were operating with high efficiency; on university campuses, palm-vein recognition access gates were streamlining entry and exit management for students and faculty; and in remote regions, portable biometric data collection devices were shouldering the critical task of identity re...

  Cables are mainly composed of three basic structural elements: a conductive core, an insulation layer and a sheath layer. It is mainly composed of three basic structural elements: conductive core, insulating layer and sheath layer. There is no strict boundary between wires and cables, but in a broad sense, cables have complex structures and complex sheaths, while wires have relatively simple structures. Some only have a conductor and an insulating layer, and some only have a waxed light protective layer or a light soft protective layer. The conductive core of the wire and cable is used to transmit electric current. In order to reduce power loss and voltage drop, the conductive wire core is generally made of copper and aluminum with high conductivity. The function of the insulating layer is to prevent the current from leaking in the radial direction and ensure the safety of use. Therefore, the insulating layer is required to have good electrical insulation properties. Heat resista...
