A method is described of calculating and verifying the integrity of data in a data communication system. The system comprises a base station and one or more remote stations, such as in an RFID system. The method includes transmitting a select instruction from the base station to the one or more remote stations, the select instruction containing a data field which matches a portion of an identity or other data field in one or more of the remote stations; transmitting from a selected remote station or stations a truncated reply containing identity data or other data of the remote station but omitting the portion transmitted by the base station; calculating in the base station a check sum or CRC from the data field originally sent and the truncated reply data received and comparing the calculated check sum or CRC with the check sum or CRC sent by the remote station.

A digital-imaging based system for and method of reading graphical indicia, including code symbols, on objects such as, but not limited to, code symbol menus by the user simply pointing his or her finger at the particular code symbol on the code symbol menu to be read, while digital images of the code symbol menu and the pointing finger are automatically captured, buffered and processed.

A method for generating a unique device ID for each addressable device in a stack of multiple addressable devices by encoding a device ID for one device in the stack and determining a device ID for each of the other devices based on the device ID of an adjacent device in the stack.

A multi-window management apparatus includes: an activating icon display unit for displaying activating icons 60, 62, 64 and 66 on a display screen 56; a window display unit opening, when activating icon 64 is designated, a window 72 corresponding to activating icon 64 next to activating icon 64; and a window arranging unit for rearranging and displaying, when activating icon 64 is designated, a window 68 that has been open, and activating icons 60, 62 and 66 other than the designated activating icon 64, such that these are arranged along the longer side direction of display screen 56 not to be overlapping on an area where the new window 72 is to be opened.

A transaction apparatus (10) includes a multifunction card (12) and a portable terminal (14). The multifunction card includes a programmable memory (18) and a magnetic stripe (16) thereon. The programmable memory on the card is used to store indicia corresponding to account data which is input to the memory by reading with the terminal magnetic stripe data from a plurality of conventional magnetic stripe cards. The programmable memory further includes data representative of cash value as well as instructions, prompt messages and icons presented in conducting transactions. A user is enabled to operate the apparatus to select one of the accounts stored in memory, and to write account data corresponding to the selected account to the magnetic stripe of the card. The user is also enabled to use the apparatus to enter visible indicia such as bar codes and to selectively reproduce the bar codes on the display of the apparatus. The apparatus is also selectively operative to transfer funds between accounts of the user and data representative of cash value stored on the card.

An electronic display comprises an electro-optic material (preferably an electrophoretic medium) having a plurality of pixels, and separate first, second and third sets of addressing means for addressing these pixels. Each of the pixels is associated with one addressing means in each of the three sets, such that addressing of any specific pixel requires application of signals within predetermined ranges to each of the three addressing means associated with the specific pixel being addressed.

In one embodiment, a method includes receiving a provisioning instruction including a device identifier from an external management entity, receiving the device identifier from a network device, associating the provisioning instruction the network device, and sending a portion of the provisioning instruction to the network device. The device identifier being associated with a virtual resource. The associating is based on the device identifier of the virtual resource and a device identifier of a network device. The portion of the provisioning instruction is sent to the network device based on the associating.
