I would like to use a reservation system (like Planyo.com) in connection with a door access system for a building.
The client would get an entry PIN code when he makes a reservation and with this code be able to open the electric lock in my business for the time he made the reservation ( preferably extended with about 15 minutes more before and after).
These physical access systems have their own software too or a website to log in or work via the Cloud. Examples of such access systems are... with Software: https://eldesalarms.com/product/configuration-tool/ with Cloud: https://eldesalarms.com/product/cloud-services/ with Browser: http://www.jwsltd.co.uk/wireless-access-control-door-entry-system---navigator-ip-791-p.asp
Any advise as well as an estimated cost and timeframe is welcome.
