A glitch in the Ventra card system allows free rides on the CTA, by swiping some federal ID cards.
A federal employee got on the train after accidentally swiping her work id instead of her Ventra card. She notified her employer and the cta about the problem.
Although the Federal ID cards are used to gain entry at work, it worked about 1 in every 10 swipes on the Ventra card readers. A CTA spokesman said fixing the issue is a simple process, and should be completed by Monday.
