@ThereseLogeais , sorry for the delay. I was out on vacation. Insperity offers a number of time capture devices include biometrics.
As several have pointed out, there are drawbacks as well as benefits. Implementing biometric clocks can sometimes involve working around pushbacks. We have deployed hand sanitizer dispensers next to clocks in healthcare environments. In another instance, we had to create written policies and procedures to ensure that fingerprint data was kept secure to calm privacy concerns. You also need to make sure you use the right technologies in the right environments. Don't' deploy fingerprint readers where hand injuries or heavy dirt / grease is involved. We had a problem in a casino once with clocks that used two finger biometric readers. We would get dealers and waitstaff signed up and registered. A week later, the ladies would get a pedicure with porcelain nails and the clock would no longer recognize them. (Peoples nails don't typically grow by a inch or more over night.)
Regardless, be prepared for implementation issues that are unique to the technology.
