Ventra
Ventra is an electronic fare payment system for the Chicago Transit Authority (CTA) and Pace, which replaced the Chicago Card and the Transit Card automated fare collection systems. Ventra (purportedly Latin for "windy," though the actual Latin word is ventosa) launched in August 2013, with a full system transition slated for July 2014. The payment system includes several options of payment, including a contactless smart card powered by RFID, a single day or use ticket powered by RFID, any personal bank-issued credit card or debit card that has an RFID chip, and a compatible mobile phone. Ventra is operated by Cubic Transportation Systems.
