XCOUI SF047 Smart Fingerprint Door Knob: 5 ways to unlock
Available Options
Ever locked yourself out? Not with the Smart Fingerprint Door Knob from XCOUI. This little marvel doesn’t just open doors—it opens them in five different ways: swipe your finger, tap in a code, wave an IC card, use the app (because why not?), or good old-fashioned keys for those ‘just in case’ moments. And with room for 100 fingerprints and passwords (even temporary ones for your forgetful friends), it’s like having a bouncer who never sleeps.
The high-sensitivity chip is quicker than your morning coffee ritual, recognizing you in a flash. Plus, it’s got this nifty auto-lock feature—because remembering to lock the door is so last century. Installation? A breeze. Fits standard US doors without any fuss or fancy tools. Hosting a party? Switch to passage mode and let the good times roll without fumbling for keys. And if the battery’s dead (we’ve all been there), a quick charge via Type-C saves the day. Backed by a 12-month exchange and lifetime support, it’s not just smart; it’s got your back.
