Biometric Time Clocks and Data Collection Devices

FingerScan technology has improved significantly over the last decade with the immergence of "Active Capacitive” Sensor technology. This technology allows measurements of the finger's ridges and valleys without capturing the actual fingerprint. It is this breakthrough that assures employees their unique finger patterns are not being tracked, stored, or compared to other fingerprint capturing methods, such as Law Enforcement finger print databases, while allowing employers to validate the actual identity of employees at work sites.

Competing technologies have also been developed, but often require the use of optical devices, such as cameras or scanners, to perform measurements on fingerprint lines or ridges. Unitime has chosen a Capacitive Sensor technology from Accu-Time Systems (ATS) as the most reliable and universally acceptable technology when gathering employee’s finger identification.

Active Capacitance

Active Capacitance sensors apply low level cycling voltage charges to the skin prior to performing measurements. These charges then activate the effective capacitor, and are harmless. The resulting electric field between the finger and the sensor allow the pattern of ridges and valleys of the subdermal layer of the finger to be measured in distances. The distance values are then calculated through an algorithm to store a template of each individual. Active capacitance sensors measure the ridge patterns of the subdermal layer similar to ultrasonic methods. This eliminates the need for clean, undamaged epidermal skin and a clean sensing surface that other optical fingerprint technologies may require.

Non Optical Superiority
Environments where poor lighting exist or where fingers may become particularly dirty create problems for optical devices when pictures must be taken and compared to stored templates of the finger. This is how Capacitance technology greatly differs and is superior to traditional "Finger Print" technology. Employees may also be hesitant to embrace a technology where they feel their privacy may be compromised. Traditional fingerprint technology, as used by the FBI or other law enforcement organizations, uses a much different methodology for measuring the optical differences in fingerprint patterns. These methods, such as the FBI's AFIS technology, require a 500 dpi image to be captured. FingerScan devices merely store a template derived from a mathematical algorithm for comparison of identity. Since Unitime's biometric clock options do not employ imaging methodologies, employees can be assured their privacy is not at risk, or otherwise feel they are being tracked by law enforcement organizations.

Additional Features

* Multiple fingers per employee can be enrolled to provide a backup in case of injury.
* Up to 9000 finger templates can be stored on some clock models
* False Acceptance Rates (FAR) range between 0.01% to 0.0001% based on configurable tolerances.
* "One to Many" Scanning technology allows employees to simply place their finger and walk away to begin the tracking of their time.

Unitime's Cyber Series biometric time clocks are installed at convenient locations throughout a facility to make it easy for employees to clock in. Punching is performed using finger scans, and the resulting transactions are uploaded to the host PC running the UNITIME Automated Timekeeping System in near real time.
