mogenson wrote a Rust application that lets a Flipper Zero write to a Waveshare e-Paper Tag over NFC, effectively turning the passive paper tag into a programmable display.
i12bp8 writes about TagTinker, a Flipper Zero app for exploring infrared electronic shelf-label (ESL) protocols, enabling users to transmit custom images and text to supported e-ink graphics tags. The project bundles a browser-based image preparer with dithering and colour quantisation, NFC tag scanning for auto-identifying ESL targets, and optional WiFi plugins via an ESP32-S2 bridge that render live designs (crypto prices, weather, GitHub profiles) through a Cloudflare Worker without reflashing the Flipper.
- Security relies entirely on protocol obscurity; the Flipper team noted the IR signal is "same that you use in TV remotes"
- Tags store firmware in volatile RAM, so removing the battery permanently bricks them
- A sub-$5 ESP32 + IR LED setup replicates the functionality without a Flipper Zero
- The web preparer uses Oklab 3-colour quantisation with Floyd-Steinberg, Atkinson, or Bayer dithering
- Supports monochrome and accent-colour (red/yellow) tags including SmartTAG Color 2.6 (type 1626)

Firmware and software to run an ESP32-CAM module on your Flipper Zero device. Allows capturing images and streaming live video to the Flipper Zero.
A MicroPython port for the Flipper Zero allowing users to create apps, games, and scripts using their favorite programming language without needing custom firmware.
Flipper zero apps
The FindMyFlipper app allows a FlipperZero device to emulate Apple AirTag, Samsung SmartTag, or Tile Tracker, extending its tracking capabilities. Users can clone existing tags, customize beacon intervals, and optimize for battery life. The app also generates OpenHaystack key pairs for Apple's FindMy network. Detailed instructions for installation and usage are provided.
