Abstract: An improved system and method for reflecting light includes a first light conduit and a first light source. The first light conduit has a first opening at a first end, a second opening at a second end opposite the first end, and a side opening between the first opening and the second opening. The first light source outputs a first light that initially enters the first light conduit through the side opening, reflects off the first light conduit, and exits the first light conduit through the first opening, where a second light exits the first light conduit through the second opening. The second light may be provided by a second light source that output the second light that initially enters the first light conduit through a second side opening.

Abstract: An improved system and method for data card emulation involves a portable electronic device that can emulate any one of multiple data cards corresponding to multiple entities. The portable electronic device includes a memory for storing data card information corresponding to data cards of the multiple entities, a radio frequency interface for identifying an entity and conveying information supporting a transaction between the entity and a user of the portable electronic device, a processor for retrieving from the memory a data card information of a data card of the identified entity used by the processor to support the transaction, and a touch screen display that displays information about the transaction.

Abstract: An improved system and method for data card emulation is provided that enables a single data card to emulate any one of multiple data cards. The data card includes an improved system and method for conveying data involving pulsed light that can read a barcode and can emulate a barcode. The improved system and method for conveying data may also include at least one of a magnetic stripe reader or a magnetic stripe emulator. The data card uses the improved system and method for conveying data to interface with conventional barcode and/or magnetic stripe readers, to interface with other such data cards or other devices having similar circuitry, and to interface with a data management system used to manage barcode and/or magnetic stripe information stored in a memory on the data card.
