Due to different technologies of biometrics such as fingerprint, face, iris recognition etc. Users have many questions when purchasing a biometric access control system, making it impossible to determine which technology is really suitable for their project. Below are 7 key points to consider when choosing a biometric access control system based on different situations. It is worth noting that these elements are only general criteria, as there is no single best model for different projects. It is necessary to fully consider factors such as location, environment, and application population in order to select the most suitable system.
Accuracy is the primary consideration
The accuracy of biometrics is improving as the technology matures, but it remains one of the most fundamental needs of customers. To measure the accuracy of a product, there are usually indicators such as false positive acceptance rate (FRR), false positive rate, recognition rate, and false rejection rate (FAR). Taking face recognition as an example, although it has high convenience, its recognition accuracy is affected by factors such as ambient light and recognition distance. When the user changes the face by means of makeup and plastic surgery, it will also affect the accuracy of the recognition.
User friendliness cannot be ignored
A biometric system’s success depends greatly on how well it is accepted by the users. The fingerprint sensor, for instance, will be rejected by many consumers due to its unhygienic nature. In addition, the sensor requires certain characteristics from the user’s finger when scanning .At the same time, the sensor also has certain requirements for the user’s finger when scanning. In this context, contactless technology has developed rapidly. At the level of user acceptance, cultural factors are the biggest key. Face recognition and fingerprint recognition, for example, are considered negative practices in some countries. Therefore, understanding which patterns are acceptable to users is the key to deploying biometric systems.
High security is the core
Like cybersecurity concerns, the popularity of biometric systems has also become a target for criminals trying to sabotage. At present, many criminals around the world have become a serious problem by entering interactive commands to access restricted areas or directly attack. Therefore, when choosing a biometric system, the security of the system should be considered. For example, the current AI imitates faces or fingerprints, etc. In this case, the recognition method of multi-technology fusion in the future. For example, turnstile gate + face will further improve the security of the solution. To learn more about turnstile gates, please visit Macrosafe.
Choose an affordable price
Cost is a common concern for users. Cost is often the deciding factor, especially when choosing the best and most efficient identification hardware. But users must also be clearly aware that based on advanced technology and hardware foundation, biometric access control will no longer be a traditional closed system. Its openness may generate new benefits (such as giving access control system video surveillance, building intercom, security prediction, emergency alarm and other extended application functions). Such investment will also see a return on investment in the short term.
Environmental impact recognition effect
The environment in which the access control solution is installed plays an important role in the accuracy of product identification. As mentioned above, neither facial recognition nor iris recognition will work properly in ground-light environments. These factors must be considered before deciding on the modality of the product, and the environment can be modified if required. Such as adding extra lights to enhance the light.
Whether the supporting application meets the needs
There is also the size of the application to consider when choosing a solution. It’s not only the number of devices that need to be installed, it’s not only about cost, but also about experience.
The development trend of biometrics
Due to early cost and technical limitations, fingerprint identification is the most popular form on the market. But in recent years, especially in the financial and prison industries, biometrics have become popular. Among them, iris recognition is popular in some high-end projects due to its relatively high accuracy. In addition, global users are becoming more and more interested in the identification methods of the fusion of various technologies.
