Benefits of Biometric Attendance System
Biometric attendance used to record employee’s start and end times, is popular in organizations where security is an issue or where employees might falsely record time worked. Because biometric technology is more costly than other forms of time clock identification, it is important to evaluate the return on investment biometric devices provided based on two key benefits: eliminating buddy punching and establishing security access.
- With buddy punching, an employee either types a tardy employee’s PIN or swipes the employee’s badge earlier than he arrives to work or after he leaves work. The organizational costs of this kind of time theft can be enormous. The company loses money a few minutes at a time compounded across departments and locations. Biometrics makes it almost impossible for employees to defraud a time and attendance system.
- With establishing security access, the biometric system works as a security access monitor to grant or deny access to restricted areas. The cost of purchasing and maintaining magnetic or proximity identification cards, which do not prevent fraudulent access, can be eliminated.
According to Biometrics Research Group, Inc. analysts, the market for worldwide workforce management software was US$10 billion in 2010 and is forecast to reach US$18 billion by the end of 2015. The market for all biometric workforce management solutions such as cloud-, software- and hardware-based will reach US$600 million in sales by 2018.
Fingerprint versus Iris Recognition in Biometric Attendance
Fingerprint is widely accepted by civil law enforcement and forensic government applications and provides a relatively low false rejection rate and false acceptance rate when used in populations with a low incidence of “outliers” groups. Besides, fingerprint has a wide range of vendors and solutions and ability to enroll multiple fingers. However, comparing to iris, fingerprint is not as accurate as iris recognition.
Fingerprint false accept rate varies by vendor, and is approximately 1 in 100,000 while iris recognition false accept rate is 1 in 1.2 million statistically. Iris recognition had no false matches in over two million cross-comparisons, according to Biometric Product Testing Final Report. Furthermore, the large number of players means no fingerprint standards exist whereas iris recognition has one core standard, which is flexible and open to all partners, and has been the foundation for Oki, Panasonic and LG hardware solutions.
Additionally, based on occupation, trauma or disease, individual fingerprints may be obscured, damaged or changed. This means some people may need to enroll multiple times over the course of their lives. In contrast, the iris itself is stable throughout a person’s life, approximately from the age of one; the physical characteristics of the iris don’t change with age. Moreover, when using iris recognition system, the users do not have to directly expose to equipment; hence, it doesn’t contain the risk of disease transmission which has become a serious concern in Africa where the Ebola epidemic broke out for the past year.
Moreover, iris scanning has been proved totally safe to human as it does not use any lasers, bright lights or hazardous technology. Taking an example from mining industry in China where the working environment is really dirty and harsh, with iris scanning, the employees can easily integrate with attendance equipment just by looking into a camera for a few seconds and then, a video image is taken, which is non-invasive and inherently safe. Finally, iris recognition carries extremely low maintenance costs and offers seamless interoperability between different hardware vendors; the technology also has the ability to work well with other applications.
The possibilities of biometrics for employee authentication are endless. Experts attest that biometric technology is likely to be used increasingly in transactions requiring identity authentication since it virtually eliminates the ability to duplicate biometric characteristics. In time and attendance, biometrics improves the ease-of-use and accuracy of timekeeping systems while bolstering corporate security and enhancing employee privacy. Iris recognition, in particular, is moving from a niche component of high-end security systems to broader commercial and consumer applications. Technology advances in processing power, camera resolution, and illumination are making iris biometrics viable for a wide range of used cases.
