The Thumblock PC Management Software package allows administrators to register the fingerprints and PIN-codes (or both) of all users at one centralized PC with a USB fingerprint scanner. Then they can set access control rights at the PC of each individual user to each individual lock. When finished, they can upload those access control rights to the flash drive and bring the flash drive to the lock to program the lock ? directly from the flash drive. Windows software (XP, Vista and 7 Compatible) and an external fingerprint reader are both included in the package.
