Fingerprint Dominates Biometric Applications

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.

Time and Attendance

The iClock2500/2800 multimedia fingerprint time attendance terminal developed by ZKSoftware is based on the ZEM500 multimedia platform. It is the first fingerprint time attendance terminal in the world with an eight-inch TFT, 65,000 vivid colors and 800-pixel by 600-pixel resolution.

The embedded Linux system ensures stable network transmission, while top European technology provides for long-term operation. It is particularly suitable for companies that require long-distance, standalone fingerprint recognition time and attendance. It supports T9 input (English-language alphabet) by keyboard. It also edits user names and sends SMS.

Each iClock has one legally authorized MAC address, making it perfect for sophisticated Internet environments. It also supports U-disk so users can upload individualized background pictures. In addition, it has a user-friendly interface, which facilitates navigation. HID, electromagnetic and Mifare cards are optional, making multiple applications more convenient. Users can also opt to embed an advanced web server system for easier telnet browsing.

Anviz Biometric Tech has a tabletop fingerprint time attendance recorder that requires no installation. The OA101 is a standalone system with a blue LCD panel, RS-232 communi-cation and ID+password, ID+fingerprint and fingerprint only verification. The unit has a template storage capacity of 1,760 fingerprints, and image scans take less than a second. In addition, it has a 30,000-transaction storage capacity, less than 0.00001 percent false acceptance rate and less than 0.001 percent false rejection rate.

Door Locks

Adel AD-E7F4 fingerprint and keypad locks have optical sensors with high resolutions of 500 dpi. They feature three opening methods: fingerprint, code or key. A maximum of 120 fingerprints can be divided into four groups, and the locks have a built-in infrared detector, allowing users to erase individual or group users. Fingerprints can be enrolled or erased directly on the locks with no PC software required. They operate on four AA alkaline batteries and have external sockets for nine-volt batteries for use during an emergency.

Then, the Sunneo Biometrics M32a fingerprint door lock with a capacity of 100 fingerprintsfeatures high-precision semiconductor sensors that allow quicker responses at lower voltage levels. It has a false rejection rate of less than 0.02 percent and false acceptance rate of 0.0003 percent. The capture area is 18.2 millimeters by 12.8 millimeters with a sensor acceptance angle of about 30 degrees.

The unit can make 5,000 scans with standard AA alkaline batteries. The door lock also issues an alarm when power is low. The door has an electromechanical clutch that prevents forcing of the lock. It has solid heavy-duty construction (durable zinc alloy) but with a stylish design. No external wiring is required; the product weighs 2.7 kilograms.

Access Control

Dit Digital Technology's F-104L fingerprint access control stores up to 80,000 records for up to three years with the power off. It allows users to register up to 10 fingerprints each and grants user groups access at different time slots.

The F-104L also has indoor and outdoor components with the latter functioning independently as a wireless doorbell (24-chord music.) The system includes an outdoor and indoor machine for greater convenience and safety. Auto power shutdown is triggered when the product is not in use. Connection ports include USB, RS-232, RS-485 and RJ-45.

Meanwhile, Stronger Technology has released its STR68 fingerprint access control reader with three-grade management access control, error operation alarm and protective slip-on cover for fingerprint modules and keypads. The unit has a fingerprint capacity of 2,000 with a false acceptance rate of 0.0001 percent; recognition takes less than 0.7 seconds. Power consumption is less than 10 watts. It measures 195 millimeters by 130 millimeters by 55 millimeters.

The ZK Software F4+ is a combination fingerprint access control and time attendance system with card reader. It has an optical sensor, 1,500-fingerprint storage capacity, expandable memory and 50,000 time attendance record storage capacity. Multiple access modes are fingerprint only, ID number+fingerprint, ID number+password, proximity card and Mifare card+fingerprint.

It features two-second fingerprint parameter identification, 0.0001 percent false acceptance rate and 1 percent false rejection rate. In addition, it has TCP/IP or RS485 communication ports, blue LCD and two-color LED indicator, and 12-volt DC power. Product dimensions are 225 millimeters by 22 millimeters by 185 millimeters, and it weighs 2.5 kilograms. The model is CE, FCC and MIC certified and carries a 12-month warranty.


The Miaxis Biometrics FU-20 combines the company's concepts and experience in fingerprint algorithm research, security verification technology, chip design technology and customized design. The accessory with fingerprint protection ensures security and privacy of important data. It is easy to operate and there is no need to install software. Reliable hardware encryption with login, lock, screen saver, document and favorite list encryption and decryption, auto web login, and multi-user management are included as is a complete software development kit (SDK) with Windows API.

The MXFB300 fingerprint safe developed by Miaxis features Korean de s ign, s tyl i sh whi t e LCD and optical sensor; it is scratch-proof and unbreakable. It has accurate, fast identification; standard storage capacity is eight fingerprints. Stable, low-power circuits ensure long lifespan. LCD operation is prompt, easy to use; it comes with a low-power alarm and emergency door open function. The dimensions are 400 millimeters by 250 millimeters by 240 millimeters.

Final ly, Pinewave Biomet r ics Technology's EJT-01-B fingerprint safe makes use of refined materials. The robust product works more than 1 million times to detect fingerprints (false acceptance rate is 0.00001 percent; false rejection rate is 0.01 percent). It can be used up to 10 years. No residue occurs thanks to the loose slide fingerprint acquisition design. It is easy to use and has a six-volt DC power supply (four AA batteries). The memory system supports a maximum of 10 fingerprints. Customers can choose from different sizes, cases and colors to personalize their fingerprint safe.
