DEF CON will always be a cash-at-the-door conference. If you miss online registration but would still like to attend, we will be accepting the rate of regular pricing for cash and PayNow on site. 

We will be offering regular attendee pricing and student discounts for Singapore students only. Students must provide a school issued email address (@<school>.edu.sg) to receive the discounted price. If the email address is not provided, you will not be able to receive your discounted ticket. 

Preregistration guarantees you'll receive a DEF CON Singapore Human badge (as opposed to a paper badge, if we run out) when redeeming your ticket in Singapore. Badges must be picked up onsite.
