On Friday, the CTA announced Ventra's developer has met three performance standards the agency set for it in November.
Ventra had to lower the average call wait time for customers to five minutes or less, process 99 percent of card reader taps in 2.5 seconds or less, and ensure that vending machines and card readers are operational 99 percent of the time.
Those standards have to be maintained for another month before the CTA begins to transition all CTA fare payments to Ventra.
