XCOUI SF047 Smart Fingerprint Door Knob: 5 ways to unlock
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.
