About Our Client
NexKey is a modern security technology company dedicated to transforming physical access. They focus on replacing traditional, cumbersome mechanical keys with a streamlined, digital-first approach. Their target audience includes property managers, office administrators, and individuals seeking a more secure and flexible way to manage access to buildings, offices, and shared spaces.
Challenge
Conventional access control systems often suffer from several pain points:
- Physical Limitations: Traditional keys and fobs are easily lost, stolen, or duplicated without authorization.
- Management Overhead: Managing physical access for a large number of people or multiple locations is complex and time-consuming.
- Inflexibility: Existing systems (like standard MVVM or MVC architectures) often lack the scalability needed to integrate new hardware or features rapidly.
- Security Gaps: Standard systems may not offer real-time monitoring or robust encryption for data in transit and at rest.
Solution
NexKey developed a highly sophisticated Android application built on a Modular-Based Architecture. This design prioritizes:
- Modularity: Encapsulating distinct functionalities (Unlock, Key Sharing, Authentication) into independent modules for enhanced flexibility and reusability.
- Hybrid Unlocking: Supporting both Nearby Unlock via Bluetooth Low Energy (BLE) and Remote Unlock via WiFi to provide seamless access regardless of location.
- Digital Key Management: A centralized Key Sharing Module that allows users to share digital keys with customizable permissions and expiration dates.
- Security First: Implementation of Encrypted SharedPreferences, HTTPS enforcement with certificate pinning, and Role-Based Access Control (RBAC).
