What is an IoT-based smart lock?
An IoT (Internet of Things)-based smart lock is a lock that is connected to the internet. This means you can control it from your smartphone or computer.
With our smart lock solution, you can lock or unlock doors, monitor who enters or exits, and grant temporary access — all without handing over physical keys. It’s all managed effortlessly through a simple mobile app or web interface.
What do we do?
We use IoT (Internet of Things) technology to create smart lock systems that connect to devices in real-time. The mobile app, web app, and hardware work together in real-time to provide smooth, connected access control.
No need to carry a physical key — simply log in through the app, and the door unlocks instantly.
Smart Lock Feature
Online check-in and check-out
Users get an entry pass on the app. No keys are needed.
Role-based access
Each user gets access according to their roles — such as staff, visitor, manager, or maintenance team.
Real-time access logs
You can see exactly who entered or exited when it happened, and which door was used — all within the app.
Remote lock/unlock
The door can be opened or closed from anywhere via a mobile or web app.
Group access control
You can add users to a group — such as ‘security team’ or ‘housekeeping’. Then you can give access to that group.
Weekly access schedule
You can give some users access only every Monday to Friday, from 9 am to 6 pm.
Monthly Schedule Access
You can give an employee access only from the 1st to the 10th of each month.
One-Time Access Pass
If you have a visitor, you can generate access for just one time — that access will expire once it is used.
Revolutionize Access Control Across Industries with Smart Lock Integration
Airbnb and Hospitality
Integration is very useful for Airbnb hosts, hotels, and guest houses. When a guest books a property, the system automatically creates a limited-time digital key that is valid for the duration of their stay. This eliminates the need for manual check-in and provides convenience to guests.
Healthcare
In nursing homes or care facilities, Smart Lock can be used to secure and control access for patients or staff. Remote door unlocking proves especially useful during emergencies, enabling instant access when it matters most.
Hostels
The check-in process for guests in hostels can be automated. A temporary digital key can be issued for each bed or room, increasing both security and convenience.
Real Estate
Real estate agents can use Smart Key to showcase properties. They can provide limited-time access to potential buyers or tenants without requiring them to be present in person.
Rentals and more
Smart Lock integration is very effective for car rentals, equipment rentals, or any place where temporary access is needed.
