Abstract

A system for transferring data between persons, for example in lieu of cash transactions, requires that each person to or from whom data is to be transferred carries a portable electronic device including a memory. Data transfer means in the form of data recording devices are provided at fixed locations which cooperate with the portable electronic devices to transfer data into or out of the portable electronic devices. Preferably both functions may be effected at each location. Data taken from a portable electronic device may be recorded in another portable electronic device for transfer elsewhere. The portable electronic devices may be in the form of flat cards in which logic microstructures are encapsulated.

Claims

1. A system for data transfer between a first and a second population of persons, the persons in each of said populations being at dispersed locations, said system being characterized by including:

a. a plurality of independent data recording devices placed at fixed locations;

b. a plurality of first portable electronic devices each carried by a respective one of said persons, each said portable electronic devices comprising;

b₁. first memory means;

b₂. coupling means operable at will temporarily to couple said first memory means to one of said data recording devices;

b₃. memory control circuits coupled with said coupling means and said memory means;

said memory means and said memory control circuits being in the form of logic micro-structures;

c. each said data recording device comprising;

c₁. reading means operable to read the contents of said memory means in said portable electronic devices when said memory means is coupled to said data recording device by said coupling means;

c₂. data recording means coupled to said reading means to record data reading thereby.

2. The invention claimed in claim 1, wherein said data recording means comprises:

a. writing means disposed within said recording means;

b. at least one further independent portable electronic device including;

b₁. further memory means having a plurality of programmable sections;

b₂. externally accessible coupling means connected to said memory means and operable at will temporarily to couple said further memory means with said writing means of said recording means;

b₃. further memory control circuits coupled with said externally accessible coupling means and with said further memory means;

b₄. said further memory means and said further memory control circuits being constructed as logic micro-structures.

3. The invention claimed in claim 2 and further comprising a plurality of writing devices disposed at fixed locations, wherein:

a. said first memory means includes recording sections operable to store data to be transferred, in a readily portable form;

b. said coupling means of said portable electronic device is operable at will temporarily to couple said first recording sections of said first memory means with a said writing device;

c. each said writing device comprises writing means operable to enter data into said first memory means of a portable electronic device coupled with said writing device, whereby any person of one of said populations may receive data from any person of the other of said populations.

4. The invention claimed in claim 2 wherein said memory devices of said portable electronic means are unpowered memory means.

5. The invention claimed in claim 4 wherein said memory means of said portable electronic devices are incorporated in the interiors of said devices in an inaccessible manner.

6. The invention claimed in claim 3 wherein said recording device and a said writing device are interconnected and associated in a single data-transfer device.

7. The invention claimed in claim 2 and wherein:

a. each of said portable electronic devices includes a second memory means permanently programmed with identification data;

b. each said recording and/or writing device includes;

b₁. data entry means operable to introduce identification data into said recording and/or writing device;

b₂. identification comparator means having input arranged to be coupled to said second memory means and to said data entry means;

said identification comparator means operating to compare said programmed identification data with said introduced identification data and, when said compared data correspond, to enable said recording and/or writing device.
