## 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.

read, from the display of the mobile communication device, an encrypted fifth barcode to obtain encrypted fifth barcode data; and
decrypt the encrypted fifth barcode data to obtain fifth barcode data, the fifth barcode data indicating that the fare was successfully paid.

### Claim 5 (depends on 1)

The media reader of claim 1, wherein the key is generated remote to the media reader and the mobile communication device.

### Claim 6 (depends on 1)

The media reader of claim 1, wherein allowing the transit customer to enter the transit system at the first location includes one or more of:
removing a physical barrier at the first location; and
facilitating access through a gateless entry at the first location.

### Claim 7

A method of conducting a secure ticketing transaction by authenticating a transit customer's identity, the method comprising:
receiving, by a first media reader at a first location within a transit system, a key for performing encryption or decryption of data;
reading, by the first media reader from a display of a mobile communication device of a transit customer, an encrypted first barcode to obtain encrypted first barcode data;
decrypting, by the first media reader using the key, the encrypted first barcode data to obtain first barcode data, the first barcode data indicating a request of the transit customer to enter the transit system at the first location;
generating, by the first media reader, second barcode data indicating entry information;
encrypting, by the first media reader using the key, the second barcode data to obtain encrypted second barcode data;
displaying, by the first media reader, an encrypted second barcode containing the encrypted second barcode data;
allowing the transit customer to enter the transit system at the first location;
reading, by a second media reader at a second location within the transit system from the display of the mobile communication device, an encrypted fourth barcode to obtain encrypted fourth barcode data;
decrypting, by the second media reader using the key, the encrypted fourth barcode data to obtain fourth barcode data, the fourth barcode data indicating the entry information and a request of the transit customer to exit the transit system at the second location;
