The Difference Between Digital Signatures and Electronic Signatures

An electronic signature is a way of representing your signature on a computerized document, for example a delivery slip. The term ‘electronic signature’ can refer to several different methods of capturing a signature on a document or device. This includes methods such as using a tablet or mobile app to capture an image of a handwritten signature. It can also be simply typing your name into a signature box. An example of a commonly created electronic signature is when you sign for a delivery on the courier’s digital device.
