Biometric signatures involve verification or encryption via fingerprint, retina, iris, or voice, and are increasingly emerging as a way to ensure digital security. This type of signature is ideal for critical transactions where identity must be certified and verified.
Additionally, these advanced security features ensure the integrity of documents during and after the signing process.
While electronic signatures are still the predominant form of signature, digital signatures are expanding, and are a must-have in Europe. Because there is a lack of a common identity, each country accepts different types of identity. Due to eIDAS, Europe is slightly ahead of the U.S. in what it will accept for a digital signature.
