1, first of all, we have to go to the app store to search for mobile phone signature apps;

2. Then we can import the documents that need to be signed (expense account approval form, project work order purchase order ...). At present, several softwares on the market should all support word/pdf/excel/ pictures and so on.

Then we sign our own names or annotate the documents. After my tests, all these applications are fine. Finally, it was sent by a third party, which was fast and convenient, and solved most people's troubles without printers or scanners.
