Fingerprint sensor

– Fingerprint sensor को हार्सेल जी ने 28 अगस्त सन् 1858 को बनाया था अर्थात उस का अविष्कार किया था। – हार्सल जी का जन्म यूके के slough में हुआ था।

– 1858 की शुरुआती दौर में भारत के बंगाल क्षेत्र के जानगीरपुर में भारतीय सिविल सेना के लिए एक ब्रिटिश अधिकारी के रूप में काम करते हुए उन्होंने contrectact पर फिंगर प्रिंट लगाना शुरू किया था।

ऑप्टिकल फिंगरप्रिंट सेंसर में विजिबल लाइट का इस्तेमाल होता है। इसमें स्क्रीन के नीचे कैमरे की तरह छोटे-छोटे सेंसर्स लगे होते हैं फिंगरप्रिंट रखने पर सेंसर आपकी इमेज दे रही होती है। Learn more
