can i collect passport info

You may collect passport numbers if your purpose is not to collect these data from the general public, but from your own customers, you just need to comply with two things:

1. Add the Terms & Conditions Widget (or the Short Scrollable Terms Widget) for your users to read and agree.

2. Add a Signature Widget so your users can sign and agree to provide such sensitive information.
However, we do not allow uploads of any sensitive personal information like passports, social security cards, driver's licenses, credit/debit cards and statements, bank statements, voided cheques/checks, birth/marriage certificates, visas and photo IDs.
