| * [[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.
