Company introduction
Who we are and what we do: 
EMSi is a wireless design and technology integration partner supporting access control companies add smartphone access and mobile credentials to existing card-based systems – without ripping out what already works. Most of our customers already have deployed readers, panels, and infrastructure in the field. The challenge isn’t starting again. It’s moving forward without breaking what’s there. We design complete, end-to-end solutions: panel integration, NFC readers (supplied or co-developed if required), firmware, apps (white-labelled or integrated into an existing app), credential security, testing, and certification. Our focus is simple. Make mobile access work reliably in real buildings, across real phones, under real operating conditions. Because it’s not enough for it to work on the bench. It must work every day, on every door, on every phone.

What makes us unique:
We do not sell off-the-shelf Bluetooth products. Instead, we provide development hardware, firmware, and mobile apps needed to add Bluetooth Low Energy (BLE) to access control products – drawing on decades of experience in both Bluetooth and access control.

Access control companies specializing in RFID and biometrics are experts in their field. But introducing secure mobile credentials using Bluetooth presents a different level of engineering challenge. It requires deep understanding of RF behavior, smartphone interoperability, security architecture, and system integration to make everything work seamlessly.

EMSi brings that expertise and experience – helping customers move from prototype to certified, repeatable production across different phones, doors, and real-world operating environments.

EMSi covers the full integration path – reader hardware, firmware, mobile credentials, app integration, security architecture, testing, and certification – so nothing gets lost between suppliers. We understand legacy infrastructure. We understand open standards – including Bluetooth and PKOC. And we know how to make cards and smartphones work side by side without forcing a rip-and-replace strategy.

At EMSi, you deal with engineers who’ve built careers doing this work. Our focus isn’t selling parts. It’s getting your access control product from prototype to mass production – starting with selecting the right production grade components from day one. Our approach reduces redesign cycles, lowers engineering risk, and accelerates time to market. The result is a commercially and technologically viable product that is manufacturable at scale and operates reliably in the real world.

Working with Nordic Semiconductor:
We work closely with Nordic Semiconductor and build on their latest Bluetooth SoCs across our access control integrations. EMSi has deep experience with Nordic architecture, RF behavior, and development tools. That practical understanding allows us to design efficiently, avoid common pitfalls, and move from prototype to production with fewer surprises. For our customers, it means Nordic-based designs engineered correctly – from day one. Ready for real-world deployment and scalable manufacturing.

Which projects we focus on:
1. Mobile Credential Integration (BLE + NFC) Implementing secure smartphone credentials in access control systems using Nordic nRF53 and nRF54 Series SoCs, including PKOC support.

2. Mobile SDK Deployment Embedding BLE credential functionality into existing iOS and Android enterprise apps or supplying white-label mobile solutions.

3. Nordic-Based Reader Platforms Designing and optimizing NFC + BLE multi-function readers using nRF53 and nRF54 platforms with OSDP integration.

4. End-to-End Product Realization Supporting development from hardware architecture and firmware through certification and mass production.

5. Interoperable System Modernization Enabling legacy-to-mobile migration using open standards (BLE, PKOC, OSDP) while maintaining backward compatibility.
