The smartphone has become an essential item for most people now. From cheaper Android phones to top-of-the-line iPhones, the options are increasingly diverse and sophisticated.
The evolution of smartphones took them from handsets that simply received and made calls until they became warehouses for a lot of personal information, and even financial information. People use virtual wallets to recharge their mobile phone balances, or use their cell phone as credit or debit card when shopping. But how do you keep this information safe? How about a fingerprint reader?
Fingerprint reader for Android and iPhone
Passwords, PIN codes, patterns, and other types of codes are used for a certain degree of security in the use of smartphones. They are a single layer of security, simple, that can be overcome with a little guesswork, or a little social engineering.
Fingerprint sensors appear to give an extra layer of security to the devices. The use of fingerprint detection technology has taken off on cell phones because it allows convenient and reliable security of our data on the smartphone.
Fingerprint reader on mobile phone worth it?
When a phone with fingerprint sensor support is turned on, it initially prompts the user to enter the fingerprint data into his or her phone. The sensors track fingerprints and store them on the phone. A reader connected to the smartphone does the same thing.
The problems are that fingerprint readers are used by few applications. And they are not as safe as they seem. Fingerprint authorization processes, for example, still leave room for hackers to use process vulnerabilities. It is also very easy to copy a person’s fingerprint using relatively simple methods. Add to this the fact that few applications actually use the fingerprint reader, and we have a small white elephant, which is expensive.
Cell phone with biometric reader: still a little bit to be a good buy
We can assume that our fingerprints are not really safe. But if that’s the case, then are not they really worse than passwords? After all, we are warned several times to regularly change our passwords and PIN codes, and never use the same password for multiple devices or accounts. In the case of a fingerprint sensor, there is much less you can do to ensure variability. Once your fingerprint data is stored, your security is compromised on all devices at all times.
Apple and Google may bring more features to increase security, but the possibility of violating such security still remains. Fingerprints are not really a good solution. The same fingerprints will unlock your phone and your office computer, and any other point where biometrics is used.

Digital reader: by price, only valid for professional use
The average cost of a digital reader is 1/4 of the minimum wage. Cellular-embedded digital readers are only available in high-end devices or intermediaries, which cost between 1.5 times the minimum wage and up to more than 4 times the minimum wage. As the security of the biometric reader is not very advantageous in relation to a strong password, the reader should only be bought by those who really need it.
For example, companies where the point is made by biometric reading, medical offices where the reader is used to authorize consultations by health plan, banks and financial institutions that use such means.
The novelty is interesting. It’s just too expensive, and it’s not worth it. Soon, new password features such as self-use, and even cardiac scanning in conjunction with fingerprint can make biometric security more reliable. But we still have a few years to date.
