Badge purchases pay for running the convention. If a DoS can stop badges from being sold, that would be a problem.

In order to avoid DoS, network-based systems are a bit problematic, so might be a non-starter. If you were DT, and you wanted to create a system that could avoid Denial of Service, but meet the requirements from (1) Hotel/Casino, (2) City of Las Vegas, (3) state of Nevada, (4) US Government for conventions/gatherings (if any) *and* avoid access to people's PII, or at least reducing access to PII to the least amount required, and record only what was required, what would you suggest? Better to have it and not need it than need it an not have it.Īs for "how the COVID-19 vaccine status will be checked" I don't have an answer for you on this, but new ideas are welcome. In case it is required, I would bring whatever card/evidence was provided to you as proof of vaccination. "Also, how will the Covid vaccine status be checked and verified? Do you need to bring your CDC Covid vaccine certificate?"

If the DEF CON in-person event is cancelled, then the present plan (as of May 21, 2021) is to total the difference in price between in-person badge and the virtual badge, then subtract the cost of shipping from that, and use that result as a partial refund, then use a postal service to mail a virtual badge to the person. If you paid for a "virtual badge" those are to be mailed through some sort of postal service. If you paid for an "in-person badge" those are picked up in-person if the in-person DEF CON happens.
