Definitions

• the present invention relates to a device, system and method for data storage with the unique capability of exchanging data with another such device without any intervention of, with or through a computer, and in particular, for such a device, system and method in which data exchange is performed with a highly simplified device interface.
• Portable electronic devices for data storage are useful for data access and transfer, particularly outside of a desktop computer environment. Such devices enable the user to keep data at hand, rather than forcing the user to access such data from the memory or data storage of a single stationary computer.
• portable data storage is performed either with an electronic device that attempts to maintain all functions of the desktop computer, such as a Palm computing device for example, or with completely passive data storage devices, such as a floppy disk for example.
• a handheld computer / organizer has the advantage of being able to read, write, manipulate and display data, in addition to being able to store the data.
• the handheld computer is also relatively complex and more expensive.
• Organizers are not built to store large computer files. Even if they have this capability, they do not have a provision to exchange files, but only very specific information, such as the user's personal data.
• the floppy disk which is a very inexpensive alternative, does not allow data transfer between similar devices without any intervention of a computer, as it requires a particular type of computer to be able to access the data, which is typically a PC computer running the Windows operating system.
• the user if the user wishes to transfer data from one floppy disk to another, the user must first locate a compatible computer with a compatible operating system, which would support the data exchange by copying the data first to its memory (or hard disk) and then copying the data onto the other floppy drive.
• the background art does not teach or suggest a memory storage device which has active functions apart from passively storing data. Also, the background art does not teach or suggest a memory storage device which can transfer data directly to another such storage device through a simplified device interface,, without first transferring the data to a computer.
• the present invention overcomes these deficiencies of the background art, by providing a device, a method and a system for portable data storage and transfer through a simplified device interface. The operations of the device are restricted, in order to increase the ease of use of the device, and in order to provide certain core functions. These core functions include reading data, writing data and exchanging data with a similar device and/or with an external computer.
• the device preferably has a limited device interface, which is optionally and more preferably only able to interact with other devices according to the present invention and/or computers.
• a limited user-device interface is provided, for example in order to permit the user to view and select data for data transfer.

• data set "A” would be automatically transferred to another device upon request, and such a request is received from another device according to the present invention and/or from a computer
• data set "A” would be automatically transferred to the requesting device when the device is in a stand alone mode and is turned on.
• the user may set the permission(s) such that manual approval must be given by the user through a small display/key that might be optionally part of the device when the device receives such a request.
• the terms "computer” or “computational device” refer to a combination of a particular computer hardware system and a particular software operating system.
• a software application could be written in substantially any suitable programming language, which could easily be selected by one of ordinary skill in the art.
• the programming language chosen should be compatible with the computer by which the software application is executed, and in particularly with the operating system of that computer. Examples of suitable programming languages include, but are not limited to, C, C++ and Java.
