The goal of any access control system is to let authorized people, not just their credentials, into specific places. Only with the use of a biometric device can this goal be achieved.
A card-based access system will control the access of authorized pieces of plastic, but not who is in possession of the card. Systems using PINs require an individual only know a specific number to gain entry; but who actually entered the code cannot be determined. On the contrary, biometric devices verify who people are by what they are, whether by hand, eye, fingerprint, or voice recognition.
Biometric reductions in errors have lowered the capital costs of ID cards in recent years and the true benefit of eliminating them is realized through reduced administrative efforts. For example, a lost card must be replaced and reissued by someone. Just as there is a price associated with the time spent to complete this seemingly simple task, when added together, the overall administration of a card system is costly. Contrary to using badges, sign-ins or other ways of tracking employees, a biometric time clock assures that no employee can punch in for another, eliminating time fraud and reducing payroll costs. Because every person’s biometric characteristic (hand, fingerprint, eyes, face, etc.) is unique, a biometric time clock provides a quick, accurate, and reliable way to record in-punches and out-punches for each employee. That’s why so many companies now employ biometrics.
Benefits of Biometric Access Control & Payroll
Biometrics are fast, easy-to-use, accurate, reliable and suitable for both access control and attendance applications:
- Biometrics cannot be shared, borrowed, stolen, copied, forged or guessed
- Biometrics cannot be lost and do not need to be stored safely
- Biometric identification protects the individual from identity theft
- Biometric identification protects the employer
- Employees or sub-contractors can be deleted in seconds so there is no risk of an ex-employee using an old card or duplicating a key
Which biometric characteristic is best? There is no one "perfect" biometric that fits all needs. All biometric systems have their own advantages and disadvantages. The “best” system is the one that suits your infrastructure, culture and performance requirements.
- Hand geometry readers function in extreme temperatures and dusty environments
- Fingerprint recognition ranks high in accuracy and has the lowest cost
- Fingerprint and hand geometry systems are fast and therefore suitable for large organisations
- In medical or industrial environments where fingertips are easily injured or dirtied, hand geometry is practical
- Where hygiene is important or where religious traditions make touching offensive, facial geometry is a good choice
Biometrics are practical to use Using biometrics for identifying individuals offers some unique advantages. Tokens such as smart cards, RFID cards, photo IDs or physical keys can be lost, stolen, duplicated or left at home. Passwords can be forgotten, shared, or observed. In today's electronic world people must remember numerous passwords and PIN numbers - the result is that most people either write them down or use the same password for multiple applications - neither approach maintains security. Return on Investment
An automated system gives a quick return on investment through reduced fraud and "buddy-punching", faster payroll processing, accurate calculation of time worked and reduced management time. It simultaneously offers the benefits of improved security and consistent application of policies and procedures. An unbiased, reliable system benefits every employee level. Terminals are inexpensive, and can easily be added to extend the automated network. Data on the terminal can be transferred via a USB stick, or by linking it to a standard TCP/IP computer network. The data can then be importing into a current HR/Payroll software package, or analysed in MS Excel. Although low capital outlay is important, the initial cost of the sensor is not the only factor. With a large workforce, a complex and slow enrolment procedure can increase ongoing costs. If payroll must be imported often, good (or preferably automated) importing will be important for productivity. Good local support and the availability of an upgrade path should also be taken into account. Convenient & User-Friendly
User-friendliness is a key aspect of a successful implementation. The process should be quick and easy, such as having a picture taken by a video camera or touching a fingerprint scanner. The advantage biometric authentication provides is the ability to require more instances of authentication in such a quick and easy manner that users are not bothered by the additional requirements.
