When a document is finished signing in Mifiel, we generate two files: an XML and a PDF. The second one is the visual representation of the first one.
This PDF includes at the end one or more signature pages containing information about the document, about each signer and about Mifiel and the legality of electronic signatures in Mexico. Below you will learn what each element means.
Sections of the signature page
- Header
- Introduction
- Document & record of data integrity (NOM 151)
- Signatures and identifying information
- Footer

Footer
Contains information to verify the signed document as well as information about Mifiel:
- QR code and link: they open an internal Mifiel page to verify that the information on the signature page has not been modified.
- Independent validation link: opens the Mifiel Verifier, which is auditable and allows to verify the integrity and signatures of documents signed in Mifiel, being equivalent to an external cryptographic expert.

- Link to this support article to learn more about Mifiel and the signature page.
- Page numbering: indicates on which signature page of the document you are on and how many of them the signed document has.
For endorsable electronic promissory notes: Chain of title
If the document is an electronic promissory note endorsed using Mifiel's solution, the signature page will display a message indicating that the promissory note complies with Mexico's General Law of Credit Instruments and Transactions (Ley General de Títulos y Operaciones de Crédito). Below, the chain of title will be displayed, with the following information for each endorsement:
- Endorsement number: to be able to follow the uninterrupted sequence of endorsements.
- Endorsement statement: by default it shows the name of the endorsee (who receives the promissory note), but the endorser can customize it before endorsing the promissory note.
- Endorser: name or company name of the party endorsing the promissory note.
