Comment 9 for bug 1663295

PaILS is definitely interested in this functionality. Would it be possible to issue the applicant a temporary card number (from a pool like Gary suggested) and assign them an internet only permission group that expires say in a month. They would get an email outlining this and require them to visit the library to finalize their registration. When they visit or contact the library, you could merge if they already have an account and verify their address in your regular workflow.
