Advanced Electronic Signatures (AES) add ID verification to the electronic signature signing process. Signatures must be uniquely linked to and able to identify the signer. Signature records are capable of showing evidence of tampering.
Qualified Electronic Signatures (QES) have more stringent requirements mandating face-to-face identity verification. (The face-to-face identification can be live and in-person or via an audio/video connection.)  A QES is unique in that it’s considered legally equivalent to a handwritten signature.
