FAQs
Do small fingerprint sensors create security issues?
Yes, because small fingerprint sensors fundamentally work on smaller amounts of biometric data for authentication. Also, for a first-time match to be possible, a high-quality biometric template must be created in the initial enrolment process – and to achieve this a larger sensor is critical. Larger sensors require less touches to enrol the fingerprint – the smaller the sensor the more times an enrollee needs to touch the sensor to capture an image of the whole surface of the finger.
