Keep Security in Mind
While signing documents electronically is extremely convenient, some businesses may not accept electronic signatures. For those businesses that do accept electronic signatures, these apps will help you save time and effort compared to signing and scanning documents, however, remember to keep security in mind. If you’re signing a sensitive document, it’s wise to print it out and sign a paper copy instead of sending the document over email. Many of these apps above though use what they call “Bank-grade security systems” to be sure your information is safe. Be sure to look into that if security is a concern for you [and it should always be].
Bonus tip: CamScanner is a FREE useful app available for iOS, Android & Windows Phone used for scanning and editing documents on the fly.
