Through the middleware, citizens can sign PDF documents, contracts, tax declarations and legal submissions.

The middleware handles the complete signature workflow, from presenting the document to the citizen for review, through PIN verification, to the cryptographic signing operation.<\/p><p>This capability has transformed numerous professional and administrative workflows in Portugal. Notarial documents, legal filings and property transactions that once required physical presence now flow digitally.

It has fundamentally changed the relationship between Portuguese citizens and the state.<\/p><p>Every citizen and business in Portugal interacts with the middleware, directly or indirectly. For example, when a Portuguese citizen files their tax return online, they are using the middleware. Similarly, when a lawyer signs a court submission electronically, they are using the middleware. When a company administrator signs documents with the Commercial Registry, they are also using the middleware. In addition, when a citizen authenticates to access their health records on SNS, the middleware is working in the background.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d001618 elementor-widget elementor-widget-heading\" data-id=\"d001618\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Open Source as a Strength<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-58c3056 elementor-widget elementor-widget-text-editor\" data-id=\"58c3056\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The open-source nature of the project has proven to be one of its greatest strengths. By publishing the source code and adopting an open licence, Caixa M\u00e1gica Software and its government partners created a system with significant long-term advantages. First, the security research community can scrutinise the code at any time. Second, developers can build on it without licensing costs. Third, and most importantly, it will outlast any single organisation&#8217;s involvement.<br \/>Furthermore, the middleware has become the exclusive solution for signatures on government documents and public tenders. This has established a standard for reliable digital authentication in public procurement. Private usage continues to expand as well, with citizens increasingly turning to digital signatures for personal transactions that previously required notarial involvement. Meanwhile, integration with the Commercial Registry Authority allows citizens to sign as company administrators with verified credentials. Qualified professionals, architects, engineers, doctors and lawyers can additionally sign documents in their professional capacity through SCAP.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-792b27a elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"792b27a\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-7d61e37\" data-id=\"7d61e37\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-bbbc326 elementor-widget elementor-widget-heading\" data-id=\"bbbc326\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Collaboration and Continuity of the Citizen Card Middleware\n<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f693016 elementor-widget elementor-widget-text-editor\" data-id=\"f693016\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>The Citizen Card Middleware is not a completed project.
