Smart phones will be able to communicate with smart cards via near field communication, which will enable them to authenticate a live biometric sample with a template stored on a smart card. Standards compliance will be a key driver of adoption of this technology.
But general-purpose mobile devices will never be able to fulfil all requirements for all biometric applications. Identification of a biometric sample within a large gallery will require capture of a lot of high-quality biometric data, and this won‟t ever be practical on a device designed to perform such a breadth of consumer-based applications. There will be a role for these devices in defence and military applications, but it will likely be limited to one-to-one verification for access control or humanitarian missions. Durability will remain a critical factor for many applications where reliability is required.
