T&A (Time and Attendance): A control function that collects and traces information about employees and their working hours, such as attendance and absences.

T&A event: An event that indicates the T&A (Time and Attendance) status of employees. It records the entry and exit times of employees and calculates how many hours they worked in a certain period of time.

T&A rule: The rule defined by the administrator in order to assess and manage the hours worked by employees.

Tailgating: One of the fraudulent authentication-based access methods where a person without permission to access a restricted zone enters the restricted zone following the preceding person who has access permissions. Also called 'two-person entry,' tailgating is one of the most typical methods of gaining unauthorized access along with Piggybacking. Generally, tailgating refers to the act of gaining unauthorized access without intent, while piggybacking generally refers to the act of gaining unauthorized access with intent.

Tamper: A method for monitoring the device status. A tamper can be set so that, if the device is dislocated from the bracket on which it is installed due to external factors, an alarm is activated, or the event is recorded on the server.

TCP/IP: Abbreviation of Transmission Control Protocol/Internet Protocol. It is a protocol for communication between computers and a combination of TCP and IP.

Template: The stored data created from extracting and then encoding biometric features. It is used to identify a user by comparing it with the bio sample entered by the user in a biometrics system or on a biometrics device.

Template-on-Card: A method used to store the user information and fingerprint template on a smart card.

Termination: The act of connecting a resistance to the device located at the end of the RS-485 daisy chain. As the daisy chain connection gets longer, signal reflection occurs more frequently at the end of the daisy chain, interrupting the flow of current. A resistance can be connected to the device at the end of the daisy chain to suppress such reflections and obtain good signal quality.

Tilting Bracket: An angle adjustable bracket. This type of bracket is mainly used for face authentication devices and iris recognition devices.

Time sync: A function that synchronizes the time between different devices or different systems on a network.

Time zone: A geographical zone that uses the same time standard. It can be used to set the time of the device or BioStar for controlling access.

Transaction: A transaction is a unit of work that consists of data retrieval, updates, and other operations. In order to prevent using temporarily unmatched data from updates, a transaction is processed all at once. ACID Properties should be satisfied when a transaction is used.

Triggered action: The actions that automatically perform activities such as controlling the device and sending emails when an alarm or a certain event occurs.
