Unlike older versions of the system, current macOS handles most card readers automatically. Here are the steps:<\/p>\n

1. Reader connection (C3PO, Bit4Id, Gemplus, etc.)<\/strong><\/p>\n

The vast majority of current readers are CCID Compliant. This means that you do not need to install any manufacturer\u2019s drivers.<\/p>\n

Connect the reader to the USB port.<\/p>\n

To verify that the system recognizes you: go to System Settings > General > Information > System Report > USB. The manufacturer\u2019s name should appear.<\/p>\n

2. Installation of the DNIe Software (Indispensable)<\/strong><\/p>\n

For macOS to “understand” what is inside an electronic DNI, you need the official software of the National Police:<\/p>\n

Download the official installer from the Electronic DNI Portal.<\/p>\n

Find the macOS-specific version. The system will install a “PKCS#11 module” and the necessary settings for the browser to recognize your certificate.<\/p>\n

3. Settings in Browsers<\/strong>
\nSafari: Use the system keychain natively. Once the police software is installed, when trying to access an official website, Safari will ask you directly for the DNIe PIN.<\/p>\n

Firefox: It\u2019s the only one that usually requires an extra step. You must go to Settings > Privacy & Security > Security Devices and load the module. dylib installed by the DNIe software.<\/p>\n

4. Use with Viafirma<\/strong>
\nWith the official software installed and the reader connected, access to the Viafirma demo. The browser will automatically detect your DNIe\u2019s digital certificate.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"no-sidebar","site-content-layout":"plain-container","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[181],"class_list":["post-70315","faq","type-faq","status-publish","hentry","category-developers-en"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/faq\/70315","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/faq"}],"about":[{"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/types\/faq"}],"version-history":[{"count":2,"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/faq\/70315\/revisions"}],"predecessor-version":[{"id":100823,"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/faq\/70315\/revisions\/100823"}],"wp:attachment":[{"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/media?parent=70315"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.viafirma.com\/en\/wp-json\/wp\/v2\/categories?post=70315"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
