Abstract: A changeable cover (100) for an electronic device and method of using same in a payment system is provided. The cover (100) has a transponder (110) responsive to interrogation by an electric field. The cover provides an electronic identification number and other information in response to the interrogation signal. Also provided is a system for making payments, comprising at least one mobile station (4) which has an associated cover (100) for providing local data transfer. The system also comprises at least one point of sale terminal or the like, which has a second transceiver for providing data transfer.

Abstract: PURPOSE:To classify and display developers in use by colors clearly by forming part of a unit provided attachably and detachably to and from a main body device as part of the outer package of the main device CONSTITUTION:The main body 4 of the image forming device includes a developing device unit 6 attachably and detachably to and from its front side and a notch which is in the same shape with and a little bit larger than the unit outer package cover 6a of the developing device unit 6 is formed in the front cover 5 of the main body 4, so that the developing device unit 6 is replaced independently without opening the front cover 5 Further, while the developing device unit 6 is loaded in the main body 4, the unit other package cover 6a forms part of the front cover 5 The unit outer package cover 6a is displayed in the same color with the toner of the developer charged in the developing device unit 6

Abstract: A cover for a portable electronic device is disclosed. The cover can include at least one electrical component. For example, in one embodiment, an electrical component can be embedded in the cover. When the cover is placed on or mated with the portable electronic device, the electrical component embedded in the cover is able to interact with electrical circuitry of the portable electronic device. Advantageously, the cover can not only provide a protective and/or ornamental covering for the portable electronic device but can also augment the electrical capabilities of the portable electronic device.
