It's no secret that you and I live in the age of information technology, where sometimes there is simply no time for some things. I present to your attention the first (at least as far as I know) application for iPhone that allows you to leave an electronic signature on a document. JotNot Singature + makes it easy to sign documents electronically, that is, using an electronic signature. And, perhaps, the biggest plus is that in order to leave a signature you do not have to print the document. The application can also 'read' documents in PDF format, so you can download the zipped file for review and signature. Agree, this is very convenient, because the 'paperwork' becomes several times less, and besides, the process of document circulation is accelerating. If you need to enter your name in the document or put a date, then just for this, the application provides 'built-in fields', in which you can enter everything you need, and then insert it into the text of the document. After signing, the document can be sent by email, or placed in the cloud storage. However, when it comes to an important document, the question of data security arises. The developers of the JotNot Singature + application have foreseen everything here, the signed document can be password protected before sending. You can also set a password for all applications attached to the document. In addition to all the features described above, the application is fax friendly. True, for this you will need to install a special JotNot FAX application. Of course, the application is not perfect, and if we judge about the quality and whether the application meets all the mandatory requirements for electronic signatures, then of course the application loses a little. However, do not forget that this is just a mobile application. The fact that today such an application exists is already a 'breakthrough' !.
