Embodiments of the invention relate to payment cards and methods for making payment cards. In one embodiment, a card comprises a first layer and a second layer adjacent to the first layer. The second layer comprises a plurality of particles comprising metal, and the plurality of particles comprise at least about 15 volume % of the second layer. In another embodiment, a mixture is prepared comprising polymer and a plurality of particles comprising metal. The plurality of particles comprise at least about 15 volume % of the mixture. The mixture is pressed and an outer layer is applied. The mixture and outer layer are then cut to form the card.

A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Data may include the type of reward that a user would like to earn as a result of making a purchase or the type of reward that a user would like to utilize to at least partially pay for a purchase.

A payment card (e.g., credit and/or debit card) or other card or device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. User interfaces are provided in a number of different configurations in order to achieve a number of different functionalities.

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable to act as a magnetic stripe read-head detector and a data transmitter. A multiple layer flexible PCB may be fabricated to include multiple magnetic emulators. An emulator may include a coil that includes magnetic, ferromagnetic, or ferromagnetic, material in the coil's interior. Coils may be associated with zones. As a read-head is detected to move from zone-to-zone, coils may be activated to transmit information in those zones.

A card is provided, such as a credit card or security card, that may transmit information to a magnetic stripe reader via a magnetic emulator. The emulator may transmit the information in order to reduce the amount of circuitry needed to emulate a particular block of information. Additionally, for example, one or more buttons may be included on the card. Buttons may be includes, for example, to provide a control interface to navigate through various options of the card. Additionally, coding schemes may be selected via buttons. Furthermore, a card may be locked until a private number is entered into a card or a number may only be generated (e.g., displayed and/or emulated) once a particular private number is entered into a card.

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable of communicating information to a magnetic stripe reader. Information used in validating a financial transaction is encrypted based on time such that a validating server requires receipt of the appropriate encrypted information for a period of time to validate a transaction for that period of time. Such dynamic information may be communicated using such an emulator such that a card may be swiped through a magnetic stripe readeryet communicate different information based on time. An emulator may receive information as well as communicate information to a variety of receivers (e.g., an RFID receiver).

An integrated circuit (IC) having an on-chip electroluminescent silicon light source arrangement is disclosed. In the IC, the light source arrangement is a two-dimensional display arrangement and the IC includes an on-chip modulator operable to modulate data indicative of a state of the IC which can be displayed by the display arrangement, thereby providing an optical representation of the state of the IC.
