The increasingly common requirement to acquire all ten fingerprints means that with existing technology the officer needs to capture at least three separate images per user, four fingers on the left hand, four fingers on the right hand and the two thumbs. One of the key criteria when selecting a fingerprint authentication system for border control or law enforcement is the speed of acquisition of the subjectвЂ™s fingerprints. Flexible fingerprint sensors enable faster authentication Flexible sensors are also easier to integrate into smartcards, which is another emerging market for biometric applications. Moreover, flexible sensors can be seamlessly integrated around tight curves like automotive steering wheels, door handles and other consumer electronics devices, opening the door to new markets and use cases. Apart from being thin, light and shatterproof, a flexible fingerprint sensor can enable curved large area sensors that can image five fingers in a single acquisition without requiring the floor space of a palm sensor they offer cost reduction benefits too.

These arrays can be manufactured on existing FPD (flat panel display) manufacturing lines, but like a display, the resulting large area sensor is glass-based, limiting the robustness, flexibility and light-weight attributes of the sensor module.ДЇlexible fingerprint sensors can add value to biometric applications by providing solutions that arenвЂ™t possible with amorphous silicon sensors.

More recently, some companies have created a new generation optical fingerprint sensors that are built from large area amorphous silicon transistor arrays on glass that donвЂ™t need the bulky optics, because no demagnification is required. Rouzet Agaiby, Senior Business Development EngineerДЄ large percentage of existing fingerprint sensors on the market use silicon technology due to its maturity as well as its established supply chain.Д¬apacitive sensors have been the dominant technology because they allow compact fingerprint sensors in comparison to the main alternative approach of optical fingerprint sensors, which have been more bulky due to the optics used to de-magnify and focus the image.
