Summary of the Features

The PQI Mini USB Fingerprint Reader is a very portable fingerprint scanner. It is a cut above the rest if we are going to judge it solely by its size. You can practically take it anywhere, and it is very easy to set up. At the same time, it is compatible with the operating systems of Windows 7, 8, and 10.

When you have Windows 10 Hello, the installation process is a breeze, because once you plug in the device, your computer or laptop will do the rest. However, if you have older operating systems, you have to search for the appropriate drivers, which you have to download for the device to work.

Its best feature is the fact that not a lot of its components are exposed once it is plugged into the computer. Further, the fingerprint scanner itself does not take too much space. People with huge fingers will most definitely find out that they cannot fit one whole finger on the scanner.

Comparison with the iDOO Mini USB Fingerprint Reader

The iDOO Mini USB Fingerprint Reader and the PQI Mini USB Fingerprint Reader have the same design and the same interface. However, the former falls short in terms of its software. Now, this is a huge problem because the software of the fingerprint scanner should be flawless since it is the only barrier between the computer and human access.

If you have software that has a lot of bugs, then how else will you unlock your computer or laptop? Type on your keyboard? If you do so, then why use a fingerprint scanner in the first place? These and more are the questions that you are going to ask yourself when you are using the iDOO Mini USB Fingerprint Reader since it still has a long way to go in terms of perfecting its software.

The PQI Mini USB Fingerprint Reader, on the other hand, has been tried and tested for a long time. Even though it is not perfect, it is still a functional and reliable fingerprint scanner. These two qualities are very important if you want to switch to a fingerprint scanning method when it comes to logging in to your computer and laptop.


The PQI Mini USB Fingerprint Reader is the best fingerprint scanner if you are going to use it as a backup. Its best feature, which is its size, eventually led to its downfall, which is durability. Do not get us wrong; it can still do its job. However, as time goes by, the device breaks down and will be useless.

This device will be perfect for those people who tend to not close their computers or laptops often because this means that the fingerprint reader will not be used often. Then again, if you are someone who will keep on scanning your fingerprint, five times or more, in a day, then this is not for you.
