Abstract

A smart credit card device for allowing its owner to safely make credit transactions, which comprises a display screen; a memory for storing permanent data of the device and its owner and unique temporary dat regarding an impending specific transaction; a wireless transceiver for being in data communication with the credit company through a point o sale; input components for allowing the owner to input data essential fo performing the transactions; a processor for controlling the operation o the card device; and a power source such as a battery or a solar cell arra with a backup battery for supplying DC power to the card device.

Claims

1. A smart credit card device for allowing its owner to safely make credit transactions, which comprises

a) a display screen;

b) a memory for storing permanent data of the device and its owner and unique temporary data regarding an impending specific transaction;

c) a wireless transceiver for being in data communication with the credit company through a point of sale;

d) one or more input components for allowing said owner to input data essential for performing said transaction;

e) a processor for controlling the operation of said card device; and

f) a power source for supplying DC power to said card device.

2. The device according to claim 1, further comprising a magnetic strip attached to the card, being capable of providing the unique temporary data to a credit card reader.

3. The device according to claim 1, wherein the power source is a battery.

4. The device according to claim 1, wherein the power source is a solar cell array with a backup battery.

5. The device according to claim 1, in which a chip is installed being in a remote connection with an additional unit chip, for alerting whenever the two chips are distanced more than a predetermined distance.

6. The device according to claim 1, further comprising a communication port for transferring purchasing data from its memory to another device.

7. The device according to claim 7, wherein the port is compatible with USB.

8. A method for performing safe credit card transactions, comprising:

a) prior to making a purchase, the credit card device owner punches in a master code number;

b) sending a request to the credit card company to send back a randomly produced temporary code number to said credit card device;

c) displaying the temporary code number on the device'"'"'s display screen

d) at a point of sale (POS), and submitting the displayed temporary code number to said credit card company; and

e) at said credit card company verifying the submitted temporary code number and charging said credit card.

9. A method according to claim 8, wherein charging is executed by passing the magnetic strip through the POS'"'"'s credit card slit.

10. A method according to claim 8, wherein charging the credit card device is executed telephonically by allowing the POS to submit the serial number of the card device provided by the owner along with the temporary code number.

11. A method according to claim 8, wherein charging the credit card device is done through the internet by allowing the owner to fill in the serial number of the card device and the temporary code number.

12. A method according to claim 8, wherein sending a request for a temporary code and receiving the temporary code is done by:

a) A short distance transmission between the card device and a transceiver unit that can be done by one of the following ways;

1) Transmission is done between the card device and the transceiver unit located at the user'"'"'s cellular phone by way of Bluetooth.

2) Transmission between the card device and a transceiver unit located at the cash register by way of Bluetooth.

3) Transmission between the card device and a transceiver unit located at a Wimax antenna by way of Wimax technology.

4) Transmission between the card device and a transceiver unit located at a Wifi antenna by way of Wifi technology.

5) Transmission between the card device and a transceiver unit located at a RF antenna by way of RF technology.

6) Transmission between the card device and a transceiver unit located at the cash register by way of an infrared transmission.

b) A long distance transmission that can be done by one of the following ways;

1) Transmission between the owner'"'"'s cellular device and the credit card device company'"'"'s network center by way of cellular phone technology.

2) Transmission between the cash register and the credit card device company'"'"'s network center by way of internet.

3) Transmission between the cash register and the credit card device company'"'"'s network center by way of a phone wire line.

5) Transmission between a Wifi antenna and the credit card device company'"'"'s network center by way of Wifi technology.

6) Transmission between a Wimax antenna and the credit card device company'"'"'s network center by way of Wimax technology.

7) Transmission between an RF antenna and the credit card device company'"'"'s network center by way of an RF technology.

13. A method according to claim 8, wherein the buyer presses a button that transmits the temporary code number obtained earlier directly to the cash register'"'"'s system.

14. A method according to claim 8, wherein the buyer pre-uploads 3 temporary code numbers on the card device for 3 purchases, for limiting each purchase to a certain predetermined sum, while the display screen shows the temporary code number of the next purchase.

15. A method according to claim 14, wherein the buyer limits each purchase to a certain date.

16. A method according to claim 14, wherein the buyer enables a purchase only after a certain time from the previous purchase.
