Did You Know You Can Add More Fingerprints to Your Phone?

Fingerprint Scanner – Essential Feature

Nowadays several of the sophisticated smartphones as well as the low-end models tend to come with a fingerprint scanner. The fingerprint sensor stopped being a device, last year and started being one of the most essential parts of a contemporary smartphone. Fingerprint scanners had been an option on some of the laptop models for a long time till the concept prevailed, though they seemed to be forgotten. Apple then came on the scene and perfected it as well as made it a must-have feature.


In 2013, Apple introduced the Touch ID with the iPhone 5S and it has now become an essential feature Besides keeping the phone secure from authenticating payments, the one-touch fingerprint sensor seems to have various benefits over a pin code, though only when it seems to work. However, what several of the users are not aware of is that the fingerprint scanners on most of the smartphones and tablets tend to recognise up to five fingers.

 In the early system of the phone, it tends to run through registering a digit and then you can register more now or skip. Most of them hit `skip’ trying to run through the setup routine quickly.

Register More than one Finger

However, registering more than one finger could make utilising the scanner a lot easier and much more convenient. You can register fingers on different hand in order to unlock the phone, if one finger tends to be wet or sticky; you have the option of using the other hand.

You could use a thumb to unlock it in your hand though an index finger could be used in unlocking it on your desk. You also have the option of registering on the fingerprint of someone else, for instance a partner though the terms and conditions for some submissions including Android Pay, specially tends to prohibit digits from others registered on your device for apparent reasons.

In order to register an additional finger or four, one could find the security settings for the fingerprint scanner and then run the setup routine for new finger which tends to take a few minutes. With Android device running Lollipop, Marshmallow or N, one can go to Settings> Security > Fingerprint and begin the routine of adding another fingerprint. Before registering a new fingerprint, one may be asked for your pin or passcode.

Registering Same Finger More than Once – Increases Accuracy

In case of iPhone or iPad, users could go to the Settings app > Touch ID & Passcode > Edit the pin or passcode > Add a Fingerprint which could start the Touch ID registration for another finger. Several of the devices, tapping the fingerprint sensor with a pre-registered finger while viewing the list of fingerprints that have been registered, would identify which fingerprint tends to correspond to a particular entry.

For older devices having early fingerprint scanners, like the Samsung Galaxy S5 or Galaxy Note 4, registering the same fingerprint more than once utilising various parts of the finger every time could help in increasing accuracy as well as reduce the number of times when the finger is not recognized. From 2015 onwards, this is not essential with the majority of the fingerprint scanners on smartphones, though it could be helpful in making the fingerprint scanners on older models less frustrating.

LG's new Fingerprint Reader Sits Under a Smartphone Screen

Fingerprint Readers – Abundant in Smartphone Designs

Fingerprint readers seem to be abundant in the designs of smartphone with queries like, whether they should include them or where to accommodate them. While some of the manufacturers have opted in adding readers in the button on the front or raised area on the back of the devices, LG Innotek has come up with a latest idea of putting it under the screen of the phone.

The LG associate had announced that it had created a new fingerprint sensor which has been inserted into a small 0.01 inch space cut in the underside of smartphone glass cover enabling the designers of the device to include fingerprint reader without committed button, pads or other exposed components. LG has stated that the fingerprint recognition rates on the under-glass module are comparable to button-kind sensor and could reduce any kind of smartphone malfunctions, together with bonus of enabling phone to be waterproof as well as scratch-resistant or only designed to appear sleeker.

No announcement has been made yet by the company whether it would be utilising this new module in any of the upcoming phone. However a spokesperson of LG had informed the Korea Times that the company is in talks with some smartphone manufacturers in order to commercialize the new sensors, within the year.

LG’s Fingerprint Sensor under the Display

Few years ago, Apple had begun pioneering smartphone fingerprint sensors in its smartphone with the iPhone 5s and since then various manufacturers had introduced fingerprint sensors on their smartphones. Presently, LG is pioneering and is touting its new fingerprint sensor which tends to sit under the display which means that when one tends to place their finger on the cover glass of the display, the under glass fingerprint sensor module seems to automatically identify your fingerprint.

As announced by Jongseok Park, CEO of LG Innotek, the under glass fingerprint sensor module will eliminate dedicated buttons, pad or other elements for fingerprint recognition and will also help in making the smartphone more water resistant by decreasing the number of openings. This could also be the cause of slimmer devices in the near future.

 LG Innotek has mentioned that it has cut 0.01-inch slot towards the back of the cover display glass and has set up a fingerprint sensor in it with `supreme precision and combination technology’.

Fingerprint Sensor Module – False Acceptance Rate – FAR

It has also been stated that the fingerprint sensor module tends to have a false acceptance rate – FAR of 0.002%. Besides this, LG also informs that the adherence side of the glass as well as the fingerprint sensor is 0.0098-inch thick, with the capability of resisting the impact of a 130 gram steel ball dropped from 7.9-inch. Changhwan Kim, Head of Research and Development Centre LG has mentioned that they are concentrating on all resources to the development of the differentiated technology based on the creation of customer value and will continue to provide convenient, safe and pleasant user experience by launching innovative product.

LG has not disclosed when precisely we would start seeing this technology in smartphone or the other devices. In December last year, the company had been tipped to supply Oled displays for their forthcoming iPhone models.
