Sounds pretty sophisticated,
Im referring to something like this
I was meaning and am planning for myself a pressure pad that is normally open until you step on it, that then closes the circuit powering your reader and locking mechanism (depending on your lock whether it is electric lock N.O. or Magnetic lock N.C) sorry, I didn’t look up your lock specs.
Obviously safety issues with the electric lock if there is a fire etc. needing power to unlock so you would need a secondary egress or mechanical bypass.
link with further info and specs
