| * [[face_detection|Face detection]]: A function that, after a user's credential has been verified, takes a picture of the user's face before granting them access so that the event and an image of the user's face can be stored together. Authentication fails if the user's face is not detected. When an image of a user's face has been stored, if necessary, it is possible to identify the user by comparing the image of the face with the user ID that was recorded when the event occurred. \\ | * [[face_detection|Face detection]]: A function that, after a user's credential has been verified, takes a picture of the user's face before granting them access so that the event and an image of the user's face can be stored together.

| + | * [[mag_card|Magnetic stripe card]]: A card that stores data by altering the magnetism of its magnetic tape. For data transmission, the magnetic tape attached on one side of a magnetic stripe card must be read by a card terminal. Only limited types and small amounts of data can be stored on this type of card, and the data recorded on magnetic stripe cards can be altered or damaged upon contact with a magnet. In addition, because magnetic stripe cards do not provide sufficient security due to the fact that they do not use data [[encryption|encryption]], they are increasingly being replaced by [[ic_card|IC cards]] in various fields, including access control. \\ | ||

| + | * [[mobile_card|Mobile card]]: A card that stores user data and [[credential|credential]] data on a mobile device and performs authentications through [[nfc|NFC]] or [[ble|BLE]] technology. Mobile cards provide higher levels of security and convenience than plastic cards, and have the advantage of reducing card issuance and management expenses because they use mobile devices used by most people daily. \\ | ||

| + | * [[monitoring|Monitoring]]: A surveillance activity for specific purposes. Monitoring access control and time and attendance management refers to checking access control events and user time and attendance events, as well as checking and controlling the status of devices, doors and zones in real time. \\ | ||
