attendee social interaction
The official NFC Battle description asks attendees to tap a phone against another attendee's badge to complete an exchange, unlock collectible cards, and rank by cards collected. The organizer's August 22 closing update refers to NFC Battle in the past tense, confirming the activity ran. Neither source identifies the card payload, tag-memory configuration, app, backend, account linkage, privacy handling, or security model.
