HARFO Smart Fingerprint Door Lock: Advanced App Control
Say goodbye to fumbling for keys with the Harfo Smart Fingerprint Door Lock—it's like having a bouncer for your front door, minus the intimidating glare. This sleek gadget doesn't just keep unwanted guests out; it lets you control who gets in, right from your phone. Imagine adding your buddy to the guest list for game night without even getting off the couch. Or checking who came by while you were out (because let's be honest, we're all a little nosy).
And the ways to unlock it? There's a method for everyone: swipe your finger, tap a card, punch in a code, or go old-school with a key. Because sometimes, technology fails, and you just need a backup plan.
Here's the lowdown on what makes it tick:
- It locks itself—because we all forget sometimes—and you can decide how long it waits before doing its thing.
- Fits right into most American doors, no PhD in engineering required to install it.
- Chats nicely with Alexa and Google Assistant, though you'll need to grab a gateway separately to make that magic happen.
- Room for 50 fingerprints (because who doesn't have that many friends?), 250 passcodes, and a whopping 1000 IC cards. Party at your place?
No wires, no fuss—just a smarter way to secure your space. It's the upgrade your home didn't know it needed.

Smart Fingerprint Door Lock

before i got this, i was always fumbling for keys after a long day at work, and it felt outdated. now, it's like having a personal assistant for my door—super smooth and modern. i use it every day, and it's held up well over the couple of weeks i've had it. the self-locking feature is a lifesaver, and i appreciate the backup key option for peace of mind. it integrates well with my smart home setup, though i haven't splurged on the extra device for voice control yet. overall, it's made my life easier and my home feel more secure, which is exactly what i wanted without breaking the bank.
- Pros: incredibly easy to install and fits perfectly on my door without any hassle, which was a relief. i love that it locks itself automatically, so i never worry about forgetting. having multiple ways to unlock it, like with my finger or a code, makes it super convenient for me and my friends. being able to add or remove access from my phone is a game-changer, especially for impromptu gaming sessions.
- Cons: from what i feel, it's a bit annoying that i had to buy a separate gadget to make it work with voice assistants, which adds to the cost. the initial setup took a little longer than expected, but nothing too bad. also, while it holds a lot of fingerprints, i wish it was a bit more responsive in recognizing them every time, though it's mostly reliable.
