Kulunvalvontakortit, sometimes referred to as access control cards, are a common component of electronic access control systems. These cards are designed to uniquely identify individuals and grant or deny them entry to specific areas. The technology behind these cards varies, with magnetic stripe cards, proximity cards (often referred to as RFID cards), and smart cards being the most prevalent.

Magnetic stripe cards store data on a magnetic strip on the back, similar to credit cards. Proximity cards, however, use radio-frequency identification (RFID) technology, allowing them to be read wirelessly when held near a reader, without physical contact. Smart cards contain a microchip that can store more data and perform more complex functions, often offering enhanced security.

In a typical access control system, a card is presented to a reader located at an entry point. The reader communicates with a central control panel, which verifies the card's credentials against a database of authorized users and access permissions. If the card is valid and authorized for that specific location and time, the system unlocks the door or barrier. If not, access is denied.

Kulunvalvontakortit are widely used in various environments, including office buildings, schools, hospitals, and government facilities, to enhance security, manage employee access, and track movement within a facility. Their effectiveness relies on the secure management of cardholder data and the integrity of the access control system itself.
