Requirements

Governments, corporations and major payment networks can only implement systems usable for virtually all their citizens, employees and customers.

In such quality critical application segments, very high levels of security and convenience must consistently be achieved. All implementations require solid operational buffers for real life challenges like cut, worn, dry, wet, misplaced or feature poor fingers.

The core difficulty is to achieve acceptable levels of convenience (low number of false rejections) at uncompromised levels of security, in the most challenging quartile and decimile of the user segments. The following illustration show how false rejection rates using a medium sized senor will deteriorate in the most difficult user groups and environments.

 

 

Average FRRs of 2% or higher mean, that a significant part of a population is not able or willing to use the system.

For the reasons above, proper and realistic tests are mandatory. The various fingerprint sensor markets vary significantly in their requirements and complexity. The following illustration shows how performance and test requirements range from the easy and fault tolerant smart phone market to the quality critical governmental, payment and corporate markets.

 

 

Science, tests, certification requirements, industry experts, industry and government standards all confirm that quality critical applications segments all require large sized sensors with active capture areas of 169 mm² (ISO-minimum) or above.
