Document attachment is a new feature offered by Twala Sign whereas the users are able to attach files and documents to completed documents. Attached documents can be viewed and downloaded by the user.

One practicality of this feature is: it can be used by banks and other financial institutions to ask their customers to attach documents required for loans, in a sense avoiding in person meetings and hasting the document process. Another application of this feature may be beneficial during contract signing. After successfully signing the contracts, any documents related to the contract signing can be uploaded to the document which are accessible to the participants of the documents, essentially helping the users to manage their documents.
