I am already registered for Fanime and i was wondering what I will need with me to pick up my badge besides my I.D.
It is stated in the Pick-Up for Pre/Early Registration Badges of the Registration FAQ... http://www.fanime.com/attendee-registration-faq/
You need an electronic postcard that will be emailed when it is a little closer to FanimeCon.
QuoteQ: What do I need to pick up my badge if I purchased my membership online?
A: Please bring a valid government-issued photo ID (such as a passport, driver's license, or state-issued photo ID card) or a current Student ID. You will also need to bring the electronic postcard that will be attached to your registration account before FanimeCon. (Driver's/Learner's Permit and Birth Certificates do not count as valid government-issued photo ID.)
Q: What is the electronic postcard?
A: It is a document that lists your registration information. It will be available to you closer to FanimeCon – we will email you and make an announcement. Make sure to print out the electronic postcard and bring it with you to pick up your badge.
