Technology is evolving day by day. We have seen a period from password to pin code and now fingerprint and face unlock for device protection. Companies are still working to enhance security and provide a safe environment to their users.<\/span> The in-display fingerprint sensor is the latest technology being added to mobile phones with custom <\/span>OLED<\/span><\/a> displays. It was available on very few smartphones until last year, but now there is a larger market for the technology. Soon, we may see improvements in this technology and watch it become more common in mobile phones.<\/span><\/p>\n

Mobile Phones & Security Evolution:<\/strong><\/h3>\n

Physical Fingerprint Scanner:<\/strong><\/h4>\n

Before in-display fingerprint scanner technology, mobile devices were using both front and rear-mounted fingerprint scanners. Both in-display and physical fingerprint sensors are continuing to develop and grow. They provide a secure and efficient way to unlock a user\u2019s phone which is why many phone manufacturers started opting for this feature on new smartphones over a password or pin unlock. <\/span><\/p>\n

Face Unlock Technology:<\/strong><\/h4>\n

We were then introduced to the face unlock feature, which is another security feature added to smartphones, along with a fingerprint scanner. The security in face unlock compared to a fingerprint scanner is not as good since someone who looks very similar to you can easily unlock your mobile phone.<\/span> The reason is that there is an algorithm behind face unlock technology that creates and matches facial features. So, when the algorithm runs, it unlocks the phone if it finds a similar face pattern saved in the memory.  Major tech companies quickly found that Face ID was not as secured as manufacturers were claiming. <\/span> \u201cAlthough face recognition is better than no protection at all, it\u2019s not relatively more secure than Touch ID,\u201d written by <\/span>Forbes<\/span><\/a>.<\/span><\/p>\n

In-Display Fingerprint Technology:<\/strong><\/h4>\n

In-display Fingerprint technology only works with a custom OLED display. The first mobile phone that came with an in-display fingerprint sensor was Vivo X21. Vivo became the first company that took the risk and introduced this technology to the world. The device came with a custom OLED display which allowed the use of in-display technology. <\/span> Initially, Apple was supposed to use this technology on their iPhone X, but they went with Face ID. Later, Samsung also postponed using this technology to Samsung S10. After Vivo\u2019s first in-display device, this technology is being used by many mobile phone companies, and demand for this technology is growing day by day.<\/span> We are now seeing the use of this technology even in mid-range smartphones coming from Samsung, Vivo, Xiaomi, Oppo, and many others. There are still some issues with the technology like slow scanning process etc. that we are hopeful will be resolved soon in the coming devices. <\/span> Today, we are going to discuss in-display technology in detail. We will see how it works, its advantages and disadvantages, and more importantly, its role in helping people and making their lives easy. First, let\u2019s have a glance at the history of fingerprint readers and how it all started.<\/span><\/p>\n

History:<\/strong><\/h4>\n

The story of fingerprint readers all started in 2004 when Pantech GI100 introduced this technology. It was the first kind of mobile phone which came with a fingerprint reader. In 2007, Toshiba launched G900 and G500, which followed the same trend. Later, other manufacturers, including HTC, Motorola, and Acer, also joined the party, which Pantech GI100 started. In 2013, Apple used a fingerprint reader for the first time on iPhone 5S. They called it Touch ID. <\/span><\/p>\n

How Do In-Display Fingerprint Sensors Work?<\/strong><\/h4>\n

The basic working and scanning process between the physical fingerprint and in-display fingerprint scanner is the same. In simple words, we can say that there is a specific position under the custom touch screens where you can place your finger for the scanning process. It will unlock the device only if it matches with the saved biometric data.<\/span> There are three types of fingerprint scanners. They are the following:<\/span><\/p>\n
