If you wants to mail some paper and documents and you are going to cyber cafe and other market places to scan and mail that documents, then stop to go there and save your money.
You can yourself scan the documents with excellent visuality and mail it or share it on whatsapp also it has share option.
This is very good application and I am using this application.
Easy to use and easy to handle and easy to make documents secure.
It also upload you documents secure with its own online storage.
