Refill Latch Security!!

Hey!
So as I was putting the finishing touches on the GOZINTO diagram, I realized that my group and I overlooked a very small but important component: the latch security on the refill latch! This latch prevents the patient from gaining access to all of the pills, so it needs to be secured and only opened when a pharmacist need to refill the prescription. Again, this shows how minor details can be overlooked when designing something; these minor details can break a design no matter how strong the other design components are. So, to solve this minor but yet important problem, we discussed a security latch that will be operated via a sliding latch and motor; when access is granted via an override password inputted by a pharmacists, the motor will move the latch to the unlock position and the latch will open for the pharmacist.
