Main Functions

Worker TLD Number Search
Workers can instantly check their TLD number by entering only their date of birth on a PC near the TLD storage box, without contacting the HP team separately, reducing waiting time and improving work efficiency.
-
TLD Non-return Detection and Search
Through intelligent CCTV video analysis, the system automatically detects whether TLDs have been returned to the storage box and identifies unreturned TLD numbers in real time for systematic management.

SMS Notification (Automatic / Manual)
Return reminder SMS messages can be automatically sent to workers identified as non-returned users, and administrators can also send SMS messages manually when needed. All transmission records are stored in the database for easy tracking and history management.
