Currently, fingerprint sensors have become one of the familiar technologies on phones and tablets. So what exactly is this technology? How does it work and what are the advantages and disadvantages? Find out with TechtipsNReview.com in the article below.
1. What is a fingerprint sensor? On what principle does it work?
Fingerprint sensor – fingerprint recognition technology works on the following principle: When you place your finger on a fingerprint reader, the device scans an image of that finger and enters it into the system. The system will process the fingerprint, convert it to digital data, and then compare the characteristics of that fingerprint with the data stored in the system. If this fingerprint matches the system data then further functions will be performed.
Apple has integrated this technology on its Home button called Touch ID technology. Instead of having to enter a password for unlocking the device or application, now with just a light touch, you can quickly open the device. The Home key is designed with a Sapphire stone surface that both protects and supports the sensor to “capture” the fingerprint image on the fingertip. The metal rim around the Home key is the part that lets you know if the user’s finger has been placed in place to start the scanner.
Similar in functionality to Touch ID, other brands like Samsung phone or OPPO, Nokia, … also develop their own fingerprint sensor technology on the latest high-end devices to its affordable line. Just a light touch is that the system will recognize your fingerprint and open the device quickly.
2. Pros and cons of fingerprint sensor technology
Advantages
+ Unlock devices or apps quickly with a single tap or swipe
+ High authenticity because each person’s fingerprint is unique
+ The system will recognize many different fingers. Capacitive sensor technology will ensure that the fingerprint image must be taken from a “alive” finger (not cut off).
Defect
The fingerprint sensor is only an authentication system, not protecting the data on the user’s phone. Fingerprint security will not be effective when you yourself are in an “unconscious” state, that is, while you are sleeping or drunk… others can use your own finger to unlock the lock. easy.
In general, now fingerprint sensor technology has gradually become a criterion for high-end to low-cost product lines because of the convenience it brings.
