Q u o t e:
We are currently in the process of resending all BlizzCon 2010 registration bar codes. Now, don't panic—this is simply for your convenience. These bar codes are identical to those included in previous emails and the printable versions from your Battle.net order history.
Please be sure to bring a copy of your bar code along with a photo ID to pick up your ticket(s) at BlizzCon registration. We'll see you there!
