When I first heard about biometrics, I thought it was something out of a futuristic movie, like the scanners reading eyes, machines analyzing fingerprints, and doors opening like in sci-fi thrillers. But the more I’ve lived with it in real life, the more I’ve realized biometrics isn’t just technology, it goes beyond that, it’s deeply personal. It’s literally you, your body, your identity being turned into access.

Biometrics is about using our unique biological features like fingerprints, facial recognition, iris scans, or even voice patterns to verify who we are. Unlike a password you can forget or a card you can misplace, your fingerprint is always with you. Your eyes, your face, your voice, they are yours alone, impossible to duplicate with absolute perfection. That’s what makes biometrics both fascinating and a little scary.
I remember the first time I placed my finger on a biometric scanner in school during qaec examination, It felt weird. The small machine beeped, a green light flashed, and I was signed in for the day. I didn’t need to sign a sheet or carry an ID card anymore. At that moment, it felt convenient, but it also hit me, “This machine just recognized me by my body.” That’s powerful.
Today, biometrics has moved from being a novelty to becoming part of everyday life. I use my fingerprint to unlock my phone, I look at my device and it scans my face in milliseconds to grant me access. At airports, iris and facial scans are slowly replacing boarding passes. In banks, biometrics is now tied to transactions, making fraud harder. It’s not just about convenience, it’s about security, trust, and proof of identity.
But let’s be honest. With every amazing leap, there’s always a catch. What if the system gets hacked? You can reset a password, but you can’t change your fingerprint or grow a new iris. That’s where my mixed feelings about biometrics come in. It’s so personal, so intimate, that the idea of it being stored somewhere in a database makes me wonder, Who else has access to “me”?
This concern became very real to me when I first registered for a national ID. The officials didn’t just take my picture, they took my fingerprints, scanned my eyes, and stored everything in a central system. I remember thinking, “So, somewhere out there, there’s a digital copy of me in the government’s database.” On one hand, it feels safe, my identity is tied to something no one else can fake. On the other, it feels like I’ve handed over pieces of myself that I can never take back.
And that brings me to the link between biometrics and blockchain. Combining biometric authentication with blockchain technology is fascinating because blockchain is decentralized and tamper proof. Instead of worrying about one central server being hacked and my fingerprint being stolen, blockchain spreads the risk and builds accountability. It’s like locking your identity inside a safe that no single person or institution controls.
Thinking about it, biometrics is no longer optional, it’s the present and the future. It’s changing how we think about identity. For me, it’s personal because it has become part of my daily routine. I use biometrics without thinking when unlocking my phone, accessing apps, or even authenticating payments. But beneath the convenience, I never forget the responsibility it carries.
Biometrics tells me one thing clearly, your body is your key. That makes you both powerful and vulnerable at the same time. It’s amazing to live in a world where my face can replace a password, but it’s also a reminder to always ask the harder questions like who has my data?, how is it being stored?, and how safe is it really?
Biometrics has blurred the line between human identity and digital security. It has made me more aware of myself, more conscious of the uniqueness I carry in my very biology. It makes me think of my fingerprints not just as ridges on my skin, but as proof of my existence, my individuality.
And in a way, that’s beautiful.
