Abstract

A portable terminal includes a receiver, a barcode former configured to form barcodes and a display. The barcode former forms a barcode from the data received by the receiver and the display displays the formed barcode.

Claims

1. A portable terminal comprising:

a receiver;

a barcode former configured to form barcodes; and

a display, wherein said barcode former forms a barcode from the data received by said receiver and said display displays said formed barcode.

2. The portable terminal according to claim 1, further comprising a detector configured to detect light or a signal from a barcode reader provided near said display.

3. The portable terminal according to claim 2, wherein barcodes displayed on said display are individually updated according to the detection result of said detector.

17. The portable terminal according to claim 1, further comprising an encryption processor, wherein said encryption processor encrypts the data received by said receiver, said barcode former forms barcode data from the data encrypted by said encryption processor and said display displays said formed barcode data.

4. A portable terminal comprising:

a receiver;

a barcode former configured to form barcodes based on a received signal; and

a display including a main display and a sub-display wherein said barcode is displayed on said sub-display.

5. The portable terminal according to claim 4, wherein said sub-display has a higher resolution than said main display.

6. The portable terminal according to claim 4, wherein said main display has a color filter layer and said sub-display has no color filter layer.

7. The portable terminal according to claim 4, wherein data to be displayed on said sub-display is divided into a plurality of pieces of data and said sub-display displays a barcode a plurality of times with some pieces of data at a time.

8. The portable terminal according to claim 4, wherein said main display displays two-dimensional barcodes.

9. The portable terminal according to claim 8, wherein one-dimenisional barcodes and/or two-dimensional barcodes are adaptively displayed according to the amount of data to be displayed with barcodes or instructions.

10. The portable terminal according to claim 9, wherein a timing of updating barcode patterns to be displayed on each display is adaptively selected according to the amount of data to be displayed with barcodes or instructions.

11. The portable terminal according to claim 8, wherein a timing of updating the display of barcode patterns is selected so that one-dimensional barcodes to be displayed on the sub-display and two-dimensional barcodes to be displayed on the main display have the same amount of information displayed per unit time.

12. A portable terminal comprising:

a receiver;

a barcode former configured to form barcodes based on a received signal; and

a display configured to display said barcodes, wherein, when barcodes are displayed a plurality of times on said display, barcodes are displayed with predetermined non-display periods between barcode display periods.

13. The portable terminal according to claim 12, wherein the barcode display period is selected to be longer than the non-display period.

14. The portable terminal according to claim 12, wherein a plurality of barcodes are formed for each of a plurality of pieces of information, each piece of information is displayed with a plurality of barcodes with a predetermined non-display period between barcode display periods and the non-display period between barcodes corresponding to a break point of information is longer than the non-display period within each piece of information.

15. A portable terminal comprising:

a receiver;

a barcode former configured to form barcodes based on a received signal; and

a display configured to display said barcode, wherein, when a display section in said display displays barcodes a plurality of times, a starting portion of the barcode shows a display order number indicating the displaying order and a total number of barcodes displayed.

16. A portable terminal comprising:

a receiver;

a barcode former configured to form barcodes based on a received signal;

a display configured to display said barcode; and

a barcode display switch to display a barcode on said display, wherein when said barcode display switch is operated, entry of a preset password is requested and a barcode is not displayed when a correct password is not entered.

18. A portable terminal comprising:

a receiver configured to receive signals sent by radio;

a barcode former configured to form barcodes;

a display; and

a local radio communicator, wherein the local radio communicator searches for received identification information from data received by said receiver and said display displays the searched data as a barcode.

19. An electronic commerce system comprising,

a portable terminal;

an information transmission apparatus that sends product information or service information to said portable terminal; and

a distribution control apparatus that controls electronic commercial transaction information, wherein said portable terminal receives product information or service information through said information transmission apparatus and receives auxiliary information on said product information or service information from said distribution control apparatus.

20. The electronic commerce system according to claim 19, wherein said product information or service information sent by said information transmission apparatus is broadcast signals and said portable terminal performs bi-directional communication with said distribution control apparatus.

21. The electronic commerce system according to claim 19, wherein said auxiliary information is information suitable for the portable terminal or the portable terminal user.
