Securing cooler doors with access control products is likely to become a more common application as facilities become increasingly automated.  Without an access control system it's tough to control what is taken once the door is opened (like the coin-operated newspaper vending machines).  Have any of you seen a system that works well to secure cooler doors and interface with a system like the one pictured here, where supplies are ordered online and then picked up from the cooler?

I know that some of you will be able to help with this question from a contractor, who has all-glass doors with direct-hold magnets making noise when the doors close and when the mag-locks engage...

I recently visited a facility where security is their top priority.  Many of the doors are set to sound an alarm if they are left open for more than 6 seconds.  This presents a challenge when carts are being moved through the opening, because the doors need to stay open long enough for the carts, but need to close before the 6-second mark.  There are 10,000 employees on-site during a typical day, and leaving a door unsecure / not locked or latched can result in termination of their jobs.  Many of the doors are fire doors, which adds some extra complexity to the issue.  Almost all of the doors have access-control.
