iOS7 Passbook - "scan code" ?

If you go to the bottom of the page below and check out the passbook image there seems to be a new pass with the titile "Passbook" and a field on the right that says simply "Scan Code".

Anyone hear mention of this feature yet? I know Apple is going to cover more about passbook on Wednesday but this seems like a new feature with the Passbook app that could allow a user to scan a barcode to create a pass, which would be a big step up in functionality of the app.
