Tag Lock makes a tag permanently read-only. There is no undo, on any chip, in any app. Use it when a deployment is finished, and keep an unlocked spare.

Deck, the night mode.

Not a recolor. A mode: surfaces flip, every other rule holds.

The console is where NFCore stops being an app and starts being a bench tool. Pick a protocol, set the command, execute, and read the bytes back. Same hairlines, same spec rows, same single yellow, on a near-black surface that does not glare at 1 a.m.

  • SurfacesFlip to near-black. No pure black, no OLED smear.
  • AccentsThe yellow lightens and is finally allowed to be text.
  • ElevationLighter surfaces, not heavier shadows.
