This is the paper application, which will be used only by people who can't get to the online application, and don't use one of the community support services that will be working to enroll people who can't get online or who have literacy problems. The paper forms include several pages of instructions, and the insurance application paperwork for up to six persons. Since they are on dumb paper, the forms do not have access to the databases already containing much of the needed information.
No doubt there will be some cantankerous folks who will refuse to put their information into the infernal machines, and demand the paper forms. (Which some poor employee will then have to enter online for them, using a faster internal front end program.)
Very few folks will see these paper forms. Most individuals will be entering a small amount of information online themselves, or with a community support worker at a local library, church, or community center. (There are folks training for this, to assist people needing insurance who can't do the application themselves for various reasons.)
When someone does the online application process, they'll be able to check a box early in the process that permits their data to be presented in the online forms from the database systems holding selected tax return information and related items. The user will be asked to verify the information, or change it if it is inaccurate. The whole thing, including reading screens of explanatory material, will take minutes. Perhaps 30-40 minutes for very slow readers, 10 minutes for most of us ER types who have used a web site before.
