Made Hiring so Much Easier

What do you like best?

Made our onboarding so much easier. New hires are able to send information and get in faster! It is so much easier to be able to send this to a new hire. Now we are able to send this to them and we can see who is coming in before and prepare for our day. Spend your time on training instead of filling W2 all day. Also cleared up so much room in our filing cabinets.

What is an electronic and digital signature?

To understand the difference between a signature stamp and electronic signature, let’s consider what electronic signatures and signature stamps are. An electronic signature is a digital analogy to a handwritten signature, while a signature stamp is created using a method called hashing to formulate a unique private and public key. Both are legally binding. However, electronic signatures are much more convenient from an ease-of-use point of view because signature stamps require several keys and a digital certification for each signature (e-stamp) applied.

How can I eSign an attachment I received in my email?

airSlate SignNow helps enhance your business with a fine-tuned digital workflow. Take advantage of our integration with Gmail and sign an email attachment without leaving your inbox.
