| * [[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.

| * [[fail_safe_lock|Fail Safe Lock]]: This means that the system enters safe mode in the event of a power outage. In the event that the power supplied to the doors is cut off due to a fire, etc., the lock will be released, thereby opening the doors. \\ | * [[fail_safe_lock|Fail Safe Lock]]: This means that the system enters safe mode in the event of a power outage.

| * [[nc|NC (Normally Closed)]]: An action where the [[relay|relay]] remains closed in normal status but opens when the device operates. The current flows through the connected circuit because the relay remained closed earlier. \\ | * [[nc|NC (Normally Closed)]]: An action where the [[relay|relay]] remains closed in normal status but opens when the device operates.

| + | * [[nfc|NFC(Near Field Communication)]]: An [[rfid|RFID]] technology applied to mobile terminals to enable bidirectional transmission/reception of data at close range. With the rise in the smartphone penetration rate, this technology is increasingly used in various fields such as finance and communications, and it is also applied in access control in the form of mobile ID cards. \\ | ||

| + | * [[osdp|OSDP(Open Supervised Device Protocol)]]: The standard RS-485 protocol developed by enhancing the Wiegand interface, through which only unidirectional communication from a reader to a controller was possible. This protocol enables processing of large amounts of data in a bidirectional reader-controller communication environment, as well as transmitting biometric data. Supporting this protocol also enables connectivity between third-party devices, so you can simply replace an existing system's items as necessary. \\ | ||

| * [[overtime|Overtime]]: The time worked that is more than the daily working hours set by the Labor Standards Act or the company regulations. Overtime may include early work, extra work, holiday work, etc. \\ | * [[overtime|Overtime]]: The time worked that is more than the daily working hours set by the Labor Standards Act or the company regulations.
