Traveler Information Devices - Payment Device Functionality
The 'Payment Device' enables the electronic transfer of funds from the user of a service (I.e. a traveler) to the provider of the service. Potential implementations include smart cards that support payment for products and services, including transportation services and general purpose devices like smart phones that support a broad array of services, including electronic payment. In addition to user account information, the payment device may also hold and update associated user information such as personal profiles, preferences, and trip histories.
