## What it is
TagTinker is a Flipper Zero application for researching infrared electronic shelf label (ESL) protocols, letting users transmit custom images and text to supported e-ink tags. It includes a browser-based image preparation tool that dithers and converts images into Flipper-ready BMP files.

## Use cases
- send custom images to electronic shelf labels via infrared
- study and reverse-engineer ESL IR protocols
- display digital art on e-ink tags
- identify ESL tags by scanning their NFC chip
- prepare and dither images for e-ink displays in the browser
- explore IoT security of obscure wireless protocols
- render live weather or crypto tiles on shelf labels with a WiFi dev board

## When to choose
- you own a Flipper Zero and want to experiment with infrared ESL tags
- you are researching the security of electronic shelf label protocols
- you want to display custom artwork or text on e-ink shelf labels
- you need a browser tool to convert images to Flipper-ready BMPs

## When to avoid
- you need a general-purpose IR remote or TV blaster tool
- you have no Flipper Zero hardware
- you want to modify ESL tags without risking bricking battery-powered tags
- you need commercial or production ESL deployment tooling

## Facets
- artifact type: application
- maturity: active
- function: security, image-processing, developer-tools
- domain: iot, security, hardware, graphics
- platform: embedded, browser, cross-platform
