Fingerprint is the dominant biometric technology in use at businesses. Chinese vendors are taking advantage of research from the Chinese Academy of Sciences as well as Texas Instrument's industry-leading DSP and analog technology to launch fingerprint recognition devices for use in door locks, access control devices, safes, keyboards, USB drives and time attendance machines. Fingerprint recognition access control products are available in wired and wireless versions. Some feature LCD screens with Chinese and English language interfaces and sliding covers as well as tampering and forcing alarms. They can store up to thousands of users with false rejection rates of less than 1 percent and false acceptance rates of less than 0.0001 percent. Other access control products feature RJ-45, RS-232, RS485 and TCP/ IP network communication. Combination products are equipped with optical sensors that support multiple access modes: fingerprint only, ID number+fingerprint, ID number+password, proximity card and Mifare card+fingerprint. Some door locks register up to 100 fingerprints. Registry takes about 0.5 seconds and comparison time is approximately one second. The locks read fingerprints from any angle and a digital display enables deletion of enrolled entries. Key-in passwords and mechanical access keys are supported. Simple fingerprint door locks can be used for a very long time with standard AA alkaline batteries. An alert is sent when power is low. Likewise, many safes work with four AA batteries.
