Identity card issued by the employer is the typical mechanism to identify an employee. However, verifying each and every card presented by personnel requires a dedicated person or an automated system. Credentials, such as an identity card, are more effectively verified using an automated system. However, most of the verification systems are incapable of verifying if the person who presented the credential is actually its owner. Similar is the case where passwords or PINs are used as credentials.
Buddy punching, otherwise known as ghost punching or proxy punching, is an activity where tardy and absent employees will have their co-workers “punch” the time clock for them. This activity alone will significantly impact the profitability of a company that ends up paying wages of employees who never showed up for work. The company not only get ripped off, but the entire operation may be degraded by a shortage of personnel.
There is always a chance of sharing any type of information or material, which the employee is required to know or carry, granting unauthorized access to employer facilities. Use of biometrics will avoid such chances as the verification of the credential is what the employee is – not on what they know or have. Fingerprint, hand print, face, and eye are some of the popular biometrics used for personnel identification.
