Abstract:
1. A method comprising: determining a first location of a mobile device operated by a user; based on the first location of the mobile device, determining a first transit system in the vicinity of the mobile device; in response to determining the first transit system, automatically pushing first access data comprising a first encryption key and first fare computation data for the first transit system to the mobile device before the user pays to access the first transit system, the first encryption key being stored in a dynamically configurable memory in the mobile device, wherein the first encryption key is configured to generate a first code to obtain access to the first transit system when the mobile device interacts with a first reader at the first transit system and passes the first code to the first reader via a contactless element in the mobile device; determining a second location of the mobile device; based on the second location of the mobile device, determining a second transit system in the vicinity of the mobile device; in response to determining the second transit system, automatically pushing second access data comprising a second encryption key and second fare computation data for the second transit system to the mobile device before the user pays to access the second transit system, the second encryption key being stored in the dynamically configurable memory in the mobile device, wherein the second encryption key is configured to generate a second code to obtain access to the second transit system when the mobile device interacts with a second reader at the second transit system and passes the second code to the second reader via the contactless element in the mobile device; and providing a control instruction to the mobile device, the control instruction causing an operation to be performed on the dynamically configurable memory in the mobile device, the operation including altering a file structure or memory allocation of the dynamically configurable memory specific to the second transit system, and deleting the first encryption key stored in the dynamically configurable memory in the mobile device.
