As mentioned, the form itself is different. If you fill out the one online, you will be asked to fill out another when depositing the papers. And the asking for a photocopy of everything you deposit.
Basically they ask you to prove your solvency. In my case, what was easier was to deposit an employment letter and a copy of bank statements for the past three months. That was not on the list. I believe they ask for a letter from the bank, but I did not have time to deposit that and they accepted the bank statements as proof. I have heard others have deposited credit card statements and these have been accepted, so there is flexibility in documentation.
