Fingerprint scanner is currently very popular in the smartphone industry. Even many budget phones comes with this features. But the debut of iris scanner in Galaxy Note 7 has somehow hinted the end of the fingerprint era. In today’s article, we’ll show you which one is better for phone security.

The pros and cons of fingerprint scanner and iris scanner

First of all let’s talk about fingerprint scanner. This kind of scanning technology is considered a more efficient security method. It allows users to unlock the phone just by tapping their finger on the scanner, even when the phone is in the pocket. But this technology also has some drawbacks. Fingerprint is easy to copy. We leave our fingerprint on almost everything we touch. Moreover, there are many bad scanners (often in budget phones) that may encounter errors or fail to recognize the fingerprint when there’s too much moist on the finger.

As for iris scanner, the good thing about this technology is that eyeprint is very difficult to copy. That’s why having your phone locked by eyeprint is one of the best security method in the world. However, it’s quite not efficient, as you have to hold your phone in front of your face to unlock it. Moreover, some scanners do not work well in intense sunlights.

So iris scanner or fingerprint scanner?

When putting these two technologies together, we can see that both iris scanner and fingerprint scanner are ideal for smartphone security. This is because everybody has their own biometric data. Some passwords can be found out, but fingerprint and eyeprint can’t! They are sometimes a little too much for common smartphones users but it’s better than nothing right?

If we give priority to the security, iris scanner is the better one because as mentioned above, eyeprint is very hard to copy. But when it comes to efficiency, fingerprint scanner is the better choice because all you need to do is tapping on the sensor of your phone. Smartphones with fingerprint reader are also more affordable. So, which one do you prefer?
