nyckelkortet

Nyckelkortet is the Swedish term for a key card, referring to a physical access credential that unlocks doors, gates, or devices and may also function as an identity token within broader security systems. In workplaces, universities, hotels, and residential buildings, nyckelkortet serves as a portable credential issued to individuals with specific access rights, helping to control entry and time-based permissions.

Most modern nyckelkort are contactless smart cards or proximity cards that use RFID or NFC technology. They often conform to standards such as ISO/IEC 14443 or 15693 and may carry credentials from manufacturers like MIFARE or DESFire. Older installations may rely on magnetic stripe cards. In everyday use, a card presented to a reader communicates with a central access control system, which verifies permissions and grants or denies entry.

Management of nyckelkortet typically occurs through a centralized access control platform. Cards can be issued, suspended, or revoked, and access rights can be updated remotely. Systems may support time-based rules, multi-factor authentication (for example, PIN or mobile app verification), and integration with other security layers such as elevator access or attendance tracking.

Security considerations include handling of lost cards, risk of cloning, and tailgating. Mitigations include encryption, secure readers, anti-tailgating features, regular audits, and prompt revocation workflows. The term reflects the broader shift toward digital and centralized credential management in built environments. In Swedish contexts, nyckelkortet can refer to any such system, though specific implementations may carry brand or vendor names.
