How to sign a document from the iPhone or iPad using Mail

Mobile is increasingly important in our lives. We always carry it with us. And we could say that it is, on many occasions, our mobile office. Who has not received a document away from home that needed our signature immediately? Or simply, we receive the document while we are on public transport, on vacation, during lunch, etc. and it is not impossible to sign it when we get home or to the office because it is too late.

As we have said, we have a computer in our pocket or in our backpack - in the case of the iPad. And if we usually use the iOS "Mail" application, we can sign the file instantly. And above all very simply, the main philosophy of this Cupertino mobile platform.
