Although fingerprint time clocks provide greater security, are they worth the investment? It all depends on who you ask. Asking the owner of a motor vehicle workshop or building company will most likely result in a no. The answer could be yes if you ask the owner of a hotel or finance company.

In essence, fingerprint time clocks can only be as accurate as of the application. A impression time clock can quickly become problematic in applications that have employees with damaged or dirty fingers. It is possible for fingerprint recognition to fail for up to 5 percent of employees. 

If you have employees who are having problems, the best solution is to give them alternative methods of clocking in like a PIN number. This can lead to other employees having problems as the system's reliability is questioned.

This can be solved. But there's a downside. The fingerprint clock suppliers have set the rejection rate of the readers so that it is easy to misuse. 

Fingerprint time clocks are usually chosen to address the concern that employees might be clocking in for one another, which is possible with swipe cards or punch clock systems. Although this sounds great in theory, it is not unusual for fingerprint systems to cause more disruption or cost than the time theft losses it was created to save.

Other biometric options worth considering include vein scans and hand scans, which are less likely to fail. If you prefer biometric time clocks, then it is worth considering other time and attendance software as well as hardware technologies.
