Why It Mattered
The 2023 badges made NFC itself the badge-hacking subject, with both passive/tag-style and active reader/card-emulation hardware in the camp ecosystem.

- Notes
- Original 2000x1335 physical front photo downloaded from the official bornhack/badge2023 repository, cropped to the staged BornHack 2023 NFC badge pair, conservatively polygon-masked, scaled to the site badge canvas, and preserved as a transparent source cutout before WebP delivery conversion. The repository LICENSE is CC BY-SA 4.0; this is a shallow-depth documentary photo of two upright front PCBs, not a single-board studio packshot. The published badge.gallery delivery file is an optimized WebP generated from the rights-cleared local derivative/source with metadata stripped, WebP quality 82, and a maximum side cap of 1600 pixels when the source is larger; upstream source URL, license, and attribution remain unchanged.
