Successful Project Case Study:
Zafe Connect Smart Lock and IoT Security Platform

Zafe Connect Smart Lock

Client: European Smart Security Provider

Product: Zafe Connect (iOS & Android)

Region: Denmark, Sweden, Norway, Germany, Netherlands (Expanding Across Europe & USA, UK)

Adequate Infosoft partnered with a European security company to design and deliver Zafe Connect, a fully integrated Smart Lock & IoT Security ecosystem, we created Zafe Connect, an integrated Smart Lock and Internet of Things (IoT) based Security ecosystem.

The intention was to develop a comprehensive solution that would provide a platform to support many different types of smart locks as well as large installations throughout Europe, which can be transformed into a scalable, secure, and simple-to-use platform.

Adequate worked with the full life cycle of the product's creation (i.e., designing the hardware, engineering the firmware, providing the cloud infrastructure for the mobile applications, and designing the backend software).

Use of the Zafe Connect solution will not be limited to prototype or pilot projects, it has been developed for deployment into actual use in the marketplace on a large scale.

Today, Zafe Connect is a live production system, actively used by 1,000+ users with 5,000+ smart locks installed across multiple European countries.

End-to-End Smart Door Lock Development Services

Unlike vendors who handle only hardware or only software, Adequate Infosoft delivers complete end-to-end solutions under one roof. From PCB design to cloud deployment and mobile apps, we take full ownership of your product lifecycle.

PCB Design & Hardware Engineering

Our hardware engineers design custom, power-efficient, and compact PCBs optimized for smart door lock and security applications. We focus on:

  1. Microcontroller and SoC selection
  2. BLE, Wi-Fi, Zigbee, Thread, and NFC integration
  3. Secure element and encryption chip integration
  4. Battery optimization and low-power design
  5. EMI/EMC-compliant layouts for certifications

Each PCB is designed with real-world usage and mass manufacturing in mind.

Embedded Firmware Development

Firmware is the brain of any smart lock. Our embedded engineers develop secure, real-time, and OTA-enabled firmware that ensures reliable operation in all conditions.

We cover:

  1. RTOS-based firmware architecture
  2. Secure boot and encrypted firmware updates
  3. Bluetooth & Wi-Fi provisioning
  4. Sensor integration (fingerprint, keypad, RFID, door sensors)
  5. Offline and fail-safe operation modes

Our firmware is designed for long-term stability, not quick demos.

Smart Lock Casing & Industrial Design

Smart lock requirements include the need for a weighted, attractive design with ease of use. We support clients in designing the casing and enclosure of the smart lock so that the final product provides a great mix of durability and aesthetic qualities.

  1. Material selection (aluminum, high strength plastic)
  2. Weather resistant and tamper resistant
  3. Heat dissipation planning
  4. Manufacturing ready with 3D design

The result is a premium product that performs dependably.

Manufacturing & Production Support

Building hardware is not complete until it’s ready for mass production. Adequate Infosoft provides manufacturing-ready designs and production support, including:

  1. BOM optimization for cost efficiency
  2. Vendor and component selection guidance
  3. DFM (Design for Manufacturing) review
  4. Testing procedures and quality benchmarks

This helps you move confidently from prototype to market launch.

Cloud & Backend Setup for IoT Security Systems

A smart door lock is only as powerful as the cloud behind it. We design secure, scalable cloud architectures tailored for IoT security products.

Our cloud services include:

  1. Device authentication and identity management
  2. Real-time event logging and alerts
  3. Role-based access control
  4. Audit trails and access history
