Abstract: A payment reminder may be received by a payment reminder application executed by a computing device. The payment reminder may request payment of a vehicle loan associated with a registered combination of a vehicle identification number and an occupant identifier associated with the vehicle loan. The payment reminder application may verify appropriate vehicle occupants are available to receive the payment reminder, and may deliver the received payment reminder to the appropriate vehicle occupants at an appropriate time for occupant safety and privacy. The payment reminder application may also provide other types of reminders or messages targeted to the vehicle occupants.

Abstract: In one embodiment, an electronic bill presentment and payment system consistent with the invention comprises at least one biller system and at least one payor system in communication with a payment processing system. The payment processing system comprises a database including global information relating to the biller system and the payor system, and an application server for storing at least one modular business object containing specified instructions to govern financial transactions between the biller system and the payor system based on the global information. The application server permits replacement of a business object with another modular business object containing other specified instructions using the same global information.

Abstract: Techniques for portable devices functioning as an electronic purse (e-purse) are disclosed. According to one aspect of the invention, a mechanism is provided to enable a portable device to conduct transactions over an open network with a payment server without compromising security. In one embodiment, a device is loaded with an e-purse manager. The e-purse manager is configured to manage various transactions and functions as a mechanism to access an emulator therein. The transactions may be conducted over a wired network or a wireless network. A three-tier security model is contemplated to support the security of the transactions from the e-purse. The three-tier security model includes a physical security, an e-purse security and a card manager security, concentrically encapsulating one with another. Security keys (either symmetric or asymmetric) are personalized within the three-tier security model.
