When Clear Lake Bank and Trust was planning to use biometrics for internal security, one employee asked if they'd have to access their computer by spitting in a cup.

The employee was joking. Mostly.

"Training was the most difficult piece," Matt Ritter, senior vice president and chief information officer at the Clear Lake, Iowa bank said. "We didn't think it would be as hard to get people used to the concept."

The $337.7 million-asset Clear Lake said it has had success with its new fingerprint scanners from DigitalPersona, a California-based company that merged late last year with international security firm Crossmatch.

After Ritter and another employee spent about twelve hours installing the software, the second most time-consuming aspect of adopting the technology was training the employees on how to use it. That took about eight hours, but Ritter said it has saved the bank time on lost passwords and lockouts.

Despite some initial hesitancy, Clear Lake's employees have embraced the technology and now enjoy not having to constantly reset passwords. Some occasionally forget they need to change their login information in the DigitalPersona software instead of online, but overall Ritter said he has to field fewer calls due to lockout problems.

"The biggest value we see from it is an increase in overall productivity," Ritter said.
