1. Real-time event
After the SDK and the device communicate with each other successfully, some operations on the device (for example, connecting to the device, verifying a user, and enrolling a user) trigger corresponding events in real time, and data is transmitted to the PC (host computer). The triggered events are called real-time events. Users can monitor device states and user operations in real time through real-time events.
Shortened form of "fingerprint".
3. Fingerprint algorithm
A fingerprint algorithm refers to the algorithm used to generate and verify fingerprint templates.At present, ZKFinger 9.0 is the latest fingerprint algorithm used by ZKSoftware black & white devices. It is a high-speed algorithm with higher performance. For details, see FAQs.

4. High-speed buffer
A high-speed buffer refers to the memory requested by the SDK on a PC during usage. In the data upload or download process, data is first saved in the buffer before being processed.
5. Time slot, group, open door combination
These three terms are the most important concepts of access control.
A time slot is a time range. A time slot includes the time information of one week, and a time range is specified for each day of this week. For example, the following expression indicates a time range from 00:00 to 22:11 in each day of one week: 00002211000022110000221100002211000022110000221100002211. Generally, 50 time slots can be set in the device
group is a collection. When many users have the same access control privileges, these users can be added to the same group and use the group time slot. Then, time slots can be set for the group.
An open door combination refers to the groups that are required for unlock. If the open door combination contains only one group, it indicates that the door is opened when any of the users in this group passes verification. If the open door combination contains two or more groups, the door is opened only after all groups pass verification. For example, an open door combination contains groups A and B, the door is opened only after a member of group A and a member of group B pass verification.
6. Operation record
An operation record, also called management record, is a record generated when users or administrators operate on the device, for example, powering on/off the device and enrolling a user.
