Keyless one-time non-password lock

Background: Locks today require one or more of the following: a physical key
password
manual reset of password or physical factor

Problems:

If the physical key is lost, the lock is rendered useless


If the password is forgotten, the lock is rendered useless
manual reset of password or physical factor, which is troublesome, requires know-how and may sometimes require a third party (e.g. a programmer to add/remove a RFID card from the door system). This is not feasible for locks intended for public usage e.g. public lockers

Key idea: Introduce a lock that
requires a physical factor that the user always has (e.g. fingerprint or their company RFID card) and
locks when the physical factor is provided and unlocks when the same physical factor is provided and
set the physical factor as the "key" when the physical factor is provided during the lock
unset the physical factor as the "key" when the same physical factor is provided during the unlock i.e. the physical factor is used one-time and a different physical factor can be used as the next "key"

How it works: The lock will incorporate a physical factor reader (e.g. a biometric reader), a storage device, energy storage (e.g. battery)/power supply and embedded software:

If there is not enough energy (e.g. no power supply or dead battery), the lock remains in the state that it is i.e. locked or unlocked.

If lock is in unlock state and a physical factor is provided, the embedded software will store the physical factor information read by the physical factor reader within the storage device and trigger the lock to lock.

If lock is in lock state and a physical factor is provided, the embedded software will v...
