Investigation question
Across three defined NFC test distances, what first-attempt update success rate and end-to-end update latency does a standalone SwingTag prototype achieve, and how much energy does one display update consume?

Group 02
SwingTag: design and quantitative performance characterisation of a standalone embedded electronic shelf label
Group 02 is designing and testing SwingTag, a standalone electronic shelf label that combines an e-paper display, an STM32 microcontroller and an NFC link. The investigation measures update reliability, energy use and update latency under controlled laboratory conditions.
Intended outcome
The project aims to produce one working prototype, measure its update reliability, latency and energy use, and use those measurements to estimate battery life for hourly and daily update schedules.
Student profiles
Sergio Lephadi
I am a final-year Electrical Engineering student who enjoys doing things that make me happy and have a positive impact on people's lives. Outside of engineering, I enjoy playing football, gaming, and reading the occasional good book although, to be honest, not every book makes the cut. I also have a real love for dad jokes and enjoy bringing a bit of humour into conversations. After all, why be a maintainer? Because finishing it off is what I do!

I’m Masixole Jokanisi, a final-year Electrical Engineering student at Wits who enjoys turning ideas into practical solutions. When I’m not working on engineering projects or tutoring, you’ll probably find me playing soccer, gaming, or exploring new technology. I’m curious and always up for a good challenge with a bit of fun along the way.
