Sign in with Google and name your door. The app generates a unique, cryptographically signed QR code linked to your account — instantly.
Print the QR code or show it on a screen at your entrance. Visitors scan with any phone camera — no app needed on their end, ever.
Instant push notification with the visitor's name, selfie, and message. Talk back via walkie-talkie or live chat — even if you're miles away.
Every detail designed for how people actually answer their door — at home, at work, and on the move.
The moment a visitor scans your QR, you get a push notification with their name, a selfie, and their message — before they've even knocked.
Sub-2 second deliveryInvite family or staff to your door. Everyone gets notified. When one answers, others see it immediately.
Require a selfie, name, or custom fields before the bell rings. Know who's there before you decide to answer.
Hold to talk, release to send. Crystal-clear two-way voice between you and your visitor — right in the browser, no app needed on their side.
Works in any browserEvery QR contains a cryptographic key. Guessing a door ID doesn't work — only valid scans ring through.
Complete searchable log of every visit — who came, when, what they said, and who handled it.
Darwaza is designed for any place where someone needs to reach someone else — replacing knocks, calls, and interruptions with a simple, controlled interaction.
Each room becomes a smart contact point. Visitors can reach guests directly without going through reception, while maintaining privacy and control. Royal Palace Hotel in Dubai replaced their traditional intercom system with Darwaza — faster response, zero maintenance, and every guest interaction is tracked and accountable.
Each bed becomes a communication node. When patients need support, they scan the code and all on-duty staff are notified instantly — improving response time and accountability. ARVA Hospital in Bangkok adopted Darwaza as their patient response system, eliminating missed calls and reducing nurse response time significantly.
When someone arrives, family members — whether inside the house or away — instantly see who it is, receive their details, and respond before the door is opened. Especially valuable for elderly parents or when children are home alone.
Replaces traditional intercom systems with a more flexible solution. A single scan notifies multiple team members at once, allowing whoever is available to respond. No missed visitors, no fixed hardware, streamlined communication.
QR codes on tables. Customers scan to request service or place an order — staff are instantly notified with the table number. Reduces wait times, improves efficiency, and creates a quieter, more organized environment.
No need to share personal phone numbers with delivery riders or unknown visitors. Each room has its own QR code — residents receive requests with identity and context, maintaining privacy and control.
Guests reach residents directly through a scan — reducing reliance on guards or manual coordination. Visitor management that actually works, without expensive infrastructure.
Stay connected even when the shop is unattended. A customer scans the code, sends a message, and receives guidance in real time. No missed sales due to temporary absence.
Every property becomes an interactive touchpoint. Interested visitors scan, ask questions, and connect instantly — generating qualified leads without requiring on-site staff at all times.
A respectful, non-intrusive way to communicate with management when needed. No loud intercoms, no disruptions during prayer or service — just a quiet scan and a notification.
A QR code on your car lets anyone reach you without exposing private contact details. Blocked parking, delivery drop-off, or emergencies — safer, more controlled interactions.
Wherever there is a need to "knock," there is an opportunity for Darwaza to replace it with something more efficient, secure, and intelligent.
Traditional doorbells cost $50–$300 and need an electrician. Darwaza is a QR code printed on paper. It just works.
No app to download. No account to create. Any smartphone camera is enough to ring your door.
Everything you need to know about the world's simplest smart doorbell.
