HFkort
HFkort is a term used in Scandinavian languages to refer to high-frequency smart cards, i.e., contactless cards that operate in the high-frequency portion of the radio spectrum (typically 13.56 MHz). These cards rely on RFID technology and are associated with standards such as ISO/IEC 14443 (types A and B) and ISO/IEC 15693. Many implementations include a secure element and cryptographic keys to support authentication and data protection. HFkort cards communicate with compatible readers over short ranges, usually a few centimeters.
Common applications for HFkort include access control for buildings and campuses, public transportation smart cards, and
Operation is typically as follows: a reader emits an RF field that powers a passive card within
Relation to other technologies: HFkort is distinct from UHF cards that operate at higher frequencies (around
