GitHub - i12bp8/TagTinker: Flipper Zero app for ESL research using IR. All based on https://www.furrtek.org/?a=esl

TagTinker is a Flipper Zero application for researching infrared electronic shelf-label (ESL) protocols. It enables protocol observation, signal analysis, and controlled display experiments on authorized hardware. The app supports text/image display experiments, includes a local web-based image preparation utility, and is built on furrtek's public ESL reverse-engineering research. It is strictly scoped to home-lab and authorized research use, with explicit warnings against use in retail or commercial environments.
