Review:

If you’re managing attendance for a small-to-medium business using ZKTeco biometric devices (like K40, K80, U160, or similar), you’ve probably encountered the dreaded .dat export file. ZKTeco’s own software suite (AttLog, ZKTime, BioTime, etc.) can be heavy and overkill just to read a single DAT file.
