DingTalk Attendance offers multiple verification methods to confirm that employees clock in themselves, prevent buddy punching, and help organizations build a fair and impartial work environment. The following section describes three common verification methods that prevent buddy punching.

Three anti-buddy-punching verification methods

1

Clock-in phone recognition

Employees can only clock in with their own phones. If an Employee uses their own phone to clock in on behalf of someone else, the action is recorded and triggers a security check. Admins can review and confirm the record in the attendance history.
2

Photo clock-in

When Employees clock in—especially when visiting clients off-site—they can upload a photo taken with the client to confirm that they have arrived at the work location and started working. Admins can then review the photo in the attendance records for confirmation.
3

Facial recognition

During clock-in, facial recognition quickly verifies whether the Employee is clocking in themselves. Anyone attempting to clock in on behalf of another person will fail the facial recognition check.
DingTalk Attendance continues to enhance the product to strengthen compliance. In line with the requirements for protecting facial sensitive personal information under the Personal Information Protection Law and other relevant laws and regulations, the DingTalk platform iterates on the product promptly. For organizations that enable facial attendance clock-in, DingTalk upgrades facial base image enrollment to require separate individual authorization, and clarifies the scenarios and scope of data use. For existing facial photos (including facial clock-ins triggered by attendance errors), DingTalk optimizes data retention and applies deletion, protecting sensitive personal information in accordance with the law.
