In Humand we use Electronic Signature, which unlike the digital signature, which uses encryption techniques and requires a procedure in an authorized entity to obtain it, the electronic signature is a set of electronic data that is attached to a digital document and allows the identification of the signer (that the signer is who they say they are) and the subsequent non-modification (that when signed, the document cannot be modified).

Some important aspects to consider are:

• It is the signature mechanism and procedure used by multiple recognized platforms, such as DocuSign, HelloSign, tuRecibo, to mention a few.
• It is a type of signature that has legal validity in several countries (Mexico, Argentina, United States, Uruguay, Ecuador, Colombia, Spain, etc).
• Currently, companies listed on the stock exchange use Humand's electronic signature to sign receipts and other documents such as contracts or policies.
