Verify Mode: Press OK to display the Verify Mode interface, and press to select a value. There are three optional values 0, 1, and 2 that represent different matching modes respectively, and the default value is 1. Verify Mode 0: Only the administrator can open the lock, while the unlocking function is disabled for ordinary users. Verify Mode 1: This is a default matching mode. Users can open the lock by successfully matching their fingerprints only once. Verify Mode 2: This is a dual verification mode. The administrator can open the lock by successfully matching his/her fingerprint only once, but an ordinary user has to pass the verification in any two matching modes by using the same ID.
