I have no experience of html or Java, but I would like to create a page to do the follow simple task.

1. After scanning a QR code, a visitor will visit a cite first to enter his email.
2. After entering the email, a visitor will be directed to a page to download a PDF file (test.pdf).

I simply want to know who is interested in my presentation. Thanks a lot!
ps: hopefully, I do not need a database to store all these email entries.
