Buzzin | Touchless visitor management solution

The client wanted to build a system for access and entry tracking of different people in various buildings in a contactless manner. The main challenges were: using of NFC to open doors and sending data between iOS and Android devices, using of short-period QR codes, building a tracking algorithm that allowed us to safely give, take away and control access to the buildings, creating an NDEF message algorithm to create inquiries in Java language for Mifare Ultralight and Felica-type cards.

We started with mockups taking into account user experience, and then our clients’ designer provided the User Interface project. Based on them, we developed front-end and backend solutions for every kind of device and conducted quality assurance testing. When we were confident the system worked as planned, the client received the system for testing. We are creating new functionalities and implementing new features in Buzzin.

“The solution developed by TeaCode.io is bug-free, and everything works well. We’ve only had one incident, but it was caused by third-party integration. Still, whenever they find issues, they quickly solve them.” Founder & CEO, Buzzin
