The term "Mobile ID" can conjure up several different interpretations. In the strictest sense, it may consist of an un-tethered device used to capture one or more biometric samples from a subject. The captured data sample(s) may then be compared to other samples contained in a database resident on that device. The data may also be transmitted to and compared to samples in a central repository or an onboard computer repository located in a nearby vehicle. Such vehicles may include jurisdictional police cars, border patrol vehicles, military combat vehicles such as Humvees1, etc. This scenario allows for comparison to larger databases than otherwise available on a handheld device or in a nearby vehicle. Additionally, a device physically attached to a computer located in a vehicle that acquires biometric samples may also be considered as a Mobile ID device.
