Fingerprint reading is a very useful feature when it works properly.
However, in some cases, placing fingers on the sensor can be difficult, such as for people who perform manual labor.
If, for example, someone works outdoors or as a technician or engineer, using Touch ID is difficult, as well as when they have a demanding hobby, such as climbing or weight training.
Additionally, if you are someone who works with your hands, there is a high chance that your hands are not always clean. Various residues on your fingers can confuse the reading, which will not unlock with your touch.
So what can you do to avoid the above problems?
Start by using your middle finger for your fingerprint. It may feel a bit awkward at first, but middle fingers are used less than our index fingers and are less likely to get dirty. They are also still among our most dexterous fingers.
Using the middle finger is more convenient on Android smartphones that have the fingerprint reader on the back or the Touch ID keyboard on a Mac .
Another trick that can work well is to use the same finger multiple times over a period of time. This way, the device learns to read your fingerprint even if it has scratches and scars.
This is useful for those who don't want to change the finger they use to unlock smartphone .
Also, instead of using the front of your fingers, use the sides, especially on the thumb.
This practice works best on smartphones with side-mounted fingerprint readers.
Register your fingerprint in the system in the way you hold or use the device most often. Use the device for a few days to find out how it works best for you. This way, you will always have accuracy and will not have difficulty unlocking your device.
