Interpreting biometrics

We know that every biometric scheme has an error rate. But can the fingerprint and palm reading technology be used together to reduce the error rate?

A: Palm shape and fingerprint reading account for 80% of biometric access control applications. They are complementary because they meet different specific needs of the market. When using these two technologies on a single platform, dealers, integrators, and users can choose one of them to use appropriate and appropriate biometrics on each access point.

As a low-cost biometrics solution, fingerprint reading can be used as a supplement to palm reading, and is most suitable for access control systems with no more than 100 people. In these applications, the total number of transactions (transactions) is relatively small, so the problems caused by the higher error rate of fingerprint reading technology will only cause little inconvenience, and will not cause major problems. However, in any case, adding biometrics to the access control system using cards can greatly improve security.

For small applications, cost is a key issue, and fingerprint products can meet this demand. For example, fingerprint reading can be an ideal choice for laboratories visited by 10, 20 or 30 people. This has become the main field of fingerprint product growth. They can also be used in small places, such as medical cabinet doors. In addition, they are also suitable for indoor use.

Using these two biometric technologies at the same time, customers and integrators can mix and match palm prints and fingerprint readings in the same facility, ensuring the best combination of cost and technology on each portal.

How can the best use of fingerprint or palm reading?

A: With the rapid decline of false-rejection and failure-to-enroll, the price of palm reading also increases as the number of users and transaction volume increases. Palm reading not only keeps bad guys out of the door, but also ensures that good people can gain access to any size application. This flexibility is why they are more expensive.

Therefore, in small applications of 50 or even 100 people, the inconvenience caused by the higher error rate of fingerprint reading is not a big deal, which is not surprising. However, 100 or more people require a large amount of processing, such as the daily processing capacity of 50,000 to 250,000 at the San Francisco International Airport in the United States, which becomes a major event.

According to research, about 2% to 4% of people are not suitable for fingerprint recognition technology because of dry skin. This makes fingerprint scanning unsuitable for large-scale applications. If 1,000 people need to pass each day, you will not be able to provide solutions for the 40 people who cannot pass. Relatively speaking, iris recognition is accurate, but its disadvantage is that it is too slow. We need to let people pass in a reasonable time.

For the same reason, it is extremely easy to use palm reading, and its error rate is only 0.01%, which ensures that this system can be used by both large and small crowd applications. Low error rate is extremely important when registering 100 or more people. When there are constant exceptions that cannot be registered that need to be dealt with, the patience of users and administrators drops quickly, not to mention the potential security risks.

If installed outdoors or in harsh environments, palm reading is also the best choice. The core technology of the palm reading unit allows them to work in harsh environments, including high and low temperature environments. Special fences can resist damage and storm attacks, while providing users with convenient entrance control. Both palm reading and fingerprint reading work well in an office environment.
