Planned app-issued venue-access identity artifact
Barcelona Cybersecurity Congress 2026's official app page tells visitors to download the official app and secure a digital badge, calling it the essential key for venue access. The same page says the app will be available in September 2026, before the November 3-5 Barcelona event. This record models a planned app-issued access identity artifact only; it does not infer a physical badge, a PCB, a ticket entitlement, an account or credential format, or a final access workflow.
Planned printable networking identity artifact
Barcelona Cybersecurity Congress 2026's official app page says that, with the event digital badge, visitors can print a Networking Badge to facilitate connections with fellow attendees. It names the registration desk and the Hall 2.1 info point as print locations. This record captures that planned printable networking artifact without assuming its physical medium, design, personal-data fields, access rights, or relationship to the separate digital venue-access badge.

David Melendez Cano reports original colored Ghost boards that attendees could choose, an ESP32-WROOM-32 platform, ESP-NOW game-server interaction, per-badge NVS identity/key material, and digitally signed questions and answers. Community reversals independently identify an ESP32-D0WD-V3, 1.77-inch ST7735 128x160 display, directional controls, and native quiz-server CTF protocol for the March 5-7 sixteenth edition at Kinepolis Madrid.
