Grab another phone/tablet/notebook, get to the door, record a video "Hi, this Nth of Month, I'm at work and cant enter (angry beeps from the door controller) and today is really Nth of Month, see (opening a site which shows a date and time, like a newspaper or stocks)"
Not sure you read my comment correctly - I mean that the employer will not be able to build a case that he did not show up to work in case his card is disabled.

Don't be ridiculous.
