For an IT professional or business owner, the "deep" cost of a crack far outweighs the license fee:

: Using cracked software or unauthorized access methods can lead to legal consequences. Software piracy is a significant issue worldwide, and companies often take strict measures against individuals and businesses that violate their licensing agreements.

: ZKTeco often provides a "Lite" or standard version of their software (like ZKTeco BioTime or ZKTime.net 3.0 ) that supports a limited number of devices or users for free.
