Abstract: A method is disclosed for enabling a user interface on a computer operated by a user to cause memory content of an electronic device distinct from the computer to be modified. A communication link may be established between the user interface and the electronic device by establishing a first connection between the user interface and a server distinct from each of the computer and the electronic device, and establishing a second connection between the electronic device and the server. The user interface may be used to communicate with the server via the first connection so as to cause the server to communicate with the electronic device via the second connection and thereby cause new information to be added to the memory of the electronic device via the second connection.

Abstract: A portable electronic device may be configured to present information identifying a coupon or rebate offer concerning a product or service in a machine-readable format at a point of sale. The portable electronic device may additionally or alternatively be configured to electronically receive information identifying a coupon or rebate offer concerning a product or service while disposed at a first location, and to store the information in memory so that the information can be selectively retrieved from the memory and presented in a manner that enables the information to be communicated to a provider of the product or service in connection with a purchase of the product or service consummated when the portable electronic device is disposed at a second location. The portable electronic device may be further configured to, in response to the occurrence of at least one event, automatically disable a capability of the portable electronic device to present the information.

Abstract: In one embodiment, an apparatus comprises a user authenticator and a transponder. The transponder is permitted to emit a wireless signal representing information stored in the apparatus in response to a wireless interrogation signal after the user authenticator has authenticated the identity of the user. In another embodiment, an apparatus comprises, a memory, a user input, and a transponder. The memory stores at least first and second distinct codes. The user input permits a user to select any one of the at least first and second codes for transmission in response to a wireless interrogation signal. The transponder emits a wireless signal representing the selected one of the at least first and second codes in response to an interrogation signal. In yet another embodiment, a token that may be used to engage in a transaction at a point of sale comprises a substrate, a rewritable memory, and a reconfigurable display.

Abstract: In one embodiment, an apparatus comprises an electrically-controlled illumination source, and a circuit configured to control the illumination source so as cause the light source to generate at least one sequence of light pulses that mimics those a photo-detector of a bar code reader would observe from a reflected source when reading a printed bar code symbol. In another embodiment, an apparatus comprises an electronically reconfigurable, reflective display that is insensitive to a polarization of an incident illumination source, and a circuit configured to selectively configure the display to display a bar code symbol thereon.

Abstract: In one embodiment, an electronic device is used to authenticate an identity of a user to determine that the user is permitted to access restricted information on a server. In response to the electronic device authenticating the identity of the user, a software module on a computer operated by the user is permitted to access the restricted information. In another embodiment, an electronic device is used to authenticate an identity of a user. In response to the electronic device authenticating the identity of the user, the settings on a computer are altered to correspond to settings on the electronic device.

Abstract: In one embodiment an apparatus includes a housing; a user authenticator, supported by the housing, that authenticates an identity of a user; at least one memory, supported by the housing, that stores transaction information for at least first and second media; and at least one output, supported by the housing, that releases at least a portion of the transaction information to a point-of-sale (POS) terminal after the user authenticator has authenticated the identity of the user. In another embodiment, a method involves steps of: storing transaction information for at least first and second media in a memory of a device; receiving as input a user's selection of one of the at least first and second media; displaying a visual indication to the user regarding which of the at least first and second media has been selected; and transferring at least a portion of the transaction information from the device to a point-of-sale (POS) terminal.
