There are a growing number of companies offering biometric scanners as a security option.  If you are going to have biometric scanner security, it makes sense to explore your options.  While biometric security is still thought of as science fiction by many, it is becoming increasingly common to have a biometric security option on things like laptops, for example.  A laptop (Thinkpads had them at one point, I believe) is generally secured by an access password, which could conceivably be guessed or even read over a person’s shoulder.  If the laptop is used in a crowded place, such as an airport or cafe, a person could watch the owner of the laptop enter his or her password, wait until they are not looking, then steal the laptop and have access to the information contained inside it.  With many high profile cases of confidential data being stolen off of corporate laptops, companies would do well do research offerings from companies like apc biometric scanner to see if they can use biometric technology instead of passwords for their security needs.
