Abstract
Systems, methods, and devices for conducting a secure ticketing transaction at a first location within a transit system. A media reader described herein may include a barcode reader, a barcode display, and processor(s). The processor(s) may be configured to perform operations including receiving a key for performing encryption or decryption of data, reading, from a display of a mobile communication device, an encrypted first barcode to obtain encrypted first barcode data, decrypting the encrypted first barcode data to obtain first barcode data, generating second barcode data indicating entry information, encrypting the second barcode data to obtain encrypted second barcode data, displaying an encrypted second barcode containing the encrypted second barcode data, and allowing the transit customer to enter the transit system at the first location.
