In 2021 I paid in cash, showed my physical ID and vax card, and was on my way with my badge. Nothing about the exchange was recorded. They take privacy incredibly seriously, especially the goons working registration. There was also basically no COVID that year, despite DEF CON happening right during the Delta outbreak. A big nursing conference the week before got hit hard with Delta, but DEF CON took that shit seriously, and it worked well. Pretty sure there was no vax check in 2022 and 2023, and I do know some people who got COVID in those years, but people who took decent precautions were generally able to dodge it.
