The card scanner system should have had a function enabled to alert security and management if a card was scanned in for over X hours and not scanned out.X being a variable set according to overtime policy.
All too many security officers are poorly trained,lazy,and incompetent.So building checks are too often cursory rather than thorough.
I know because of working with and attempting to train such people.
And it is mostly about money; security is seen as “non-productive” expense by the client so chooses the low bidder. The low bidder hires mostly people desparate for a paycheck but pays low wages and gives minimal training.Not only those things but I have been sent persons grossly obese or with other issues that in reality prevented them from making the required patrols of the grounds or buildings.Others could not,or would not, learn and remember fairly simple duties.
Better pay,much better training,more scructiny and careful selection and a philosophy of firm but compassionate continual improvement in job performance are all needed.
I have seen too many times that the only accomplished purpose of training documents was obtaining the employee signature,regardless of the training absorbed or even given.
I've never worked for a company where the scan cards were used on exit. Not one.
I suspect it's for emergency egress. Exit turnstiles and exit doors didn't even have the card readers.
nope scanning in or swiping your card to get into the building is it, you get to your workstation clockin and start your work day. you do not swip your card to exit.
