The purpose of having authorization login in the POS is to ensure security, accountability, and proper control over sensitive transactions and operations. Authorization info acts as a checkpoint to prevent inadvertent or accidental actions within the POS system. Supervisory approval may be required to confirm the validity of certain transactions or adjustments, reducing the likelihood of errors or mistakes.
