INE Voter Credential Security Elements
The Voter Credential issued by the National Electoral Institute (INE) of Mexico is a sophisticated document designed with multiple layers of security to prevent forgery and ensure authenticity. These elements combine physical textures, chemical inks, and digital verification tools to protect the identity of the citizen and the integrity of the electoral process.
Key Facts
- Multi-layered Defense: The credential utilizes a combination of UV, OVI, and rainbow printing.
- Tactile Security: Includes embossed designs and touch elements that cannot be replicated by scanners.
- Digital Integration: Features both standard QR codes for citizens and specialized 2D codes for official INE verification.
- Visual Complexity: Employs Guilloche patterns and microtext that are invisible or distorted when photocopied.
Obverse Security Features
The front of the credential contains the most visible and complex security markers, designed to be verified through sight, touch, and specialized lighting.
Optical and Ink-Based Elements
The INE uses UV Ink, which is only perceptible under black light, to print fixed data such as "INE, MEXICO," as well as images and variable citizen data. Additionally, OVI Ink (Optically Variable Ink) is used on the map of the Mexican Republic in the lower right and the strip next to the photograph; this ink changes color depending on the angle of light.
The Rainbow Print utilizes two or more simultaneous ink colors to create regional images with a gradient effect. For high-level authentication, the Optically Variable Element (OVD) shifts colors to reveal the INE logo, a ballot box, the Mexican coat of arms, and a flag effect.

Structural and Graphic Designs
To prevent digital reproduction, the credential features Guilloche designs—intricate patterns of fine lines that appear as dots rather than lines when photocopied. Microtext is also embedded, featuring the legend "NATIONAL ELECTORAL INSTITUTE," which is illegible to the naked eye.
The Weakened Pattern integrates the security background with the photograph's border, creating a merged appearance. Furthermore, an Embossed Design simulates relief through special lines, a feature that is nearly impossible to capture via scanner or digital photography.
Tactile and Personalized Markers
The Touch Element allows users to feel the initials of the INE and an image of a ballot entering a ballot box with their fingertips. To further personalize the document, Ghost Photography with Variable Data uses software to create a unique image based on citizen data, making each credential distinct and difficult to reproduce.
Reverse Security Features
The back of the credential reinforces authenticity through a mix of traditional printing techniques and modern digital identifiers.
Visual and Physical Markers
Similar to the front, the reverse employs UV Ink to print the citizen's photograph, which reacts to black light. OVI Ink is applied to the INE logo in the upper right, providing a variable color shift. The Rainbow Print and Embossed Design (featuring the names of the country's entities) are also present to deter scanning and copying.
Additionally, Microtext is integrated into the outlines of the voting boxes, remaining invisible to the naked eye.

Digital Verification Tools
The credential includes a standard QR Code that citizens can scan with a smartphone to access INE services, such as scheduling appointments, locating modules, and verifying credential validity.
For official use, Two-Dimensional QR Codes are embedded. These are scanned via an exclusive INE application to optimize verification. The specific way data is generated in these codes guarantees the document was issued by the INE, preventing the use of altered or false credentials.
Security Elements Summary

| OVI Ink | Obverse & Reverse | Color change based on viewing angle |
| Guilloche/Microtext | Obverse & Reverse | Prevents photocopying and scanning |
| Embossed Design | Obverse & Reverse | Tactile relief effect |
| QR Codes | Reverse | Digital authentication and service access |
| OVD | Obverse | Dynamic imagery (Logo, Coat of Arms) |
Frequently Asked Questions
How can I tell if the OVI ink is authentic?
Authentic OVI ink will visibly change color as you tilt the credential and change the angle of light hitting the map of Mexico or the INE logo.
What is the difference between the two types of QR codes on the back?
The standard QR code is for citizen use to access public services and validity checks, while the Two-Dimensional QR code is for official INE application use to prevent fraud and verify issuance.
Why does the photograph look merged with the background?
This is due to the Weakened Pattern, a security design that integrates the photo border with the background to make it harder to replace the image.
Can a high-quality scanner reproduce the embossed design?
No, the embossed design simulates a physical relief that is specifically designed to be difficult or impossible to reproduce via digital photography or scanning.
What is the purpose of the Guilloche patterns?
Guilloche patterns consist of extremely fine lines that printers and photocopiers cannot replicate accurately, resulting in a series of dots instead of continuous lines on forged documents.
