A state government holds elections each year. In the past, they allowed only in-person voting and voting by mailing in a ballot. They decide to replace the mail-in ballot system with an online ballot system instead.
The new online ballot system sends a mail to residents with a PIN (Personal Identification Number), and then asks them to login with both that PIN and their government-issued Social Security number.
The old mail-in ballot system stored the ballots in a paper filing system in a secured government office, while the new online ballot system stores the votes in a database.
The original mail-in ballot system and the new online ballot system are described in the following flowcharts. Each flowchart uses the following blocks:
