FIELD OF THE INVENTION

The present invention relates to an electronic credit card providing secure controlled and reliable transaction of funds.

BACKGROUND OF THE INVENTION

The present credit card environment and systems have the following shortfalls:

- When a credit card is reported lost or stolen by a holder he or she has to contact the company or organisation that issued the card to cancel the card in order to prevent illegal transactions. Cancellation may not occur immediately if the holder is unaware that his or her card is missing.
- The present security measures undertaken by credit card companies and/or organisations through the use of “smart card” technology are inadequate to prevent fraud. Similarly the use of holographic images on credit cards does not eliminate fraud either.
- Use of a signature as a validation control may be overlooked and can be forged.
- The technology behind current credit cards is outdated and not suitable for a secure transaction via the Internet.
- It does not prevent hackers who penetrate “secure websites” to make use of credit card details for fraud.
- Giving a merchant credit card details is like giving him or her a “signed blank cheque”. Credit companies or organisations are not efficient when dealing with insincere merchants.
- The customer must rely on trusting the merchant not to misuse the credit card details.

The present invention seeks to provide an electronic credit card that attempts to overcome the shortfalls of the present credit card system.

Referring to FIG. 1, there is shown an electronic credit card including a user verifier; a code generator for generating a unique code (not shown); a storage for storing the user's account details (not shown); and a communicator. In this embodiment the user verifier includes a keypad for entry of a personal identification number (PIN) and the communicator includes a infra red communication device 5, a magnetic induction telecommunication device 6, or radio frequency telecommunication device in the form of an antenna 7. The electronic credit card also includes a display 2, an enter/confirmation button and an audio transducer 4 for providing an audible sound.
The electronic card also includes a processor for receiving input from the keypad 1 and the button 3. The processor is also arranged to control output of the display 2 and output of the audio transducer 4. The processor is further arranged to control communication via the communicator 5, 6, 7. The storage is typically in the form of non-volatile random access memory, such as FLASH RAM or other suitable memory. The processor may be for example an embedded RISC processor, such as for example one of the ARM SecuriCore family of smart card processors or a processor using the SMARTMIPs architecture, or similar, or a proprietary designed processor.
The keypad in combination with firmware control of the processor forms the user verification means. The processor under the control of firmware forms the code generator for generating the unique authorization code. The unique authorization code may comprise a unique transaction identifier, such as a number generated according to a time/date stamp or counter and/or secret-key seeded non repeating number generating algorithm, that the number and/or code does not repeat within the lifetime of the electronic credit card. The infra red communication device, magnetic communication device, or radio frequency communication device under the control of firmware control of the processor forms the communicator. The firmware may be stored in the storage and may be reprogrammed.
The electronic credit card operates by a user entering a security code, such as a PIN number into the keypad ‘I whereby the user verifier verifies that the PIN number is correct and thus the identity of the user is verified. The code generator for generating unique authorization code then generates the authorization code from the unique transaction identifier and/or the security codes. In one embodiment the unique authorization code is a function of the transaction identifier and the security code. The unique authorization code is provided along with the user's account details, to the communicator which non visually communicates these to a transaction station to facilitate an electronic funds transfer transaction. In an alternative form the security code is derived from a user biometric reading or activated when a known biometric reading is received by checking the biometric reading locally with one stored in the electronic credit card or remotely with biometric reading stored in a database in an external system.
The transaction station in combination with an electronic funds transfer system host computer must be configured to only continue with the electronic funds transfer transaction upon the receipt of the unique authorization code and account details. Each transaction can only be authorized when the unique authorization code is sent to the host computer by the transaction station.
Referring to FIG. 2, communication between the electronic credit card is shown with a transceiver device which talks with a personal computer. The transceiver device and personal computer act, in this example as the transaction station. The transaction station may then communicate via wire or wireless communications to computer networks, such as the Internet to a host computer in order for conducting the electronic funds transfer transaction.
Referring to FIG. 3, the electronic credit card communicates by it's communication means with an automatic teller machine (ATM) or an electronic funds transfer point of sale (EFTPOS) machine, which in turn communicates via standard methods to the host computer to perform electronic funds transfer, cash withdrawal or other transaction.
FIG. 4 shows a typical physical form of an electronic credit card with a keypad input device as the user verifier, and infra red receiver as part of the communicator.
FIG. 5 shows a version of the electronic credit cards with a keypad forming part of the user verifier and radio frequency antenna forming part of the communicator.
FIG. 6 shows a version of the electronic credit card with a keypad forming part of the user verifier and magnetic induction communication device 6 forming part of the communicator.

FIG. 8 shows a version of the electronic credit card with a keypad acting as part of the user verifier and a magnetic strip 9 shown in FIG. 9 providing coded information or account information as part of the communicator.
FIG. 10 shows a version of the electronic credit card with a keypad 1 forming part of the user verifier, a combination of infra red transmitter receiver 5, radio frequency antenna 7 and induction 6 forming part of the communicator.
Referring to FIG. 11, a version of the electronic credit card with a fingerprint scanner input device 10 forming part of the user verifier and an infra red transmitter receiver 5, radio frequency antenna 7 and indication means 6 forming part of the communicator.
Referring to FIG. 12, an embodiment of the electronic credit card including an eyeball or retina scanner pad 11 which forms part of the user verifier and an infra red transmitter 5, radio frequency antenna 7 and a magnetic induction device 6 form part of the communicator.
Use of the electronic credit card will prevent merchants from accessing an unauthorised transaction code as each transaction can only be generated by a unique transaction identifier by the electronic credit card. The unique authorization code is kept secret so as it is not provided to the merchant. A merchant cannot generate a unique transaction code. The electronic credit card verifies the identity of the user before it is activated. The electronic credit card can be disabled if a predetermined number of attempts to gain access to its operation fail and this will prevent fraud in the event that an electronic credit card is stolen. An authorising distributor or other authorised body could re-initialise the electronic credit card through a controlled management system used to issue the electronic credit card.
The electronic credit card can be disabled at a transaction station through a system control function by the issuing company or organisation. This will enable immediate termination or disablement of the electronic credit card if required.
Electronic credit card may download information to a computer system via one of its telecommunication modes. This will ensure data integrity at a time when power source replacement or re-charging. Furthermore it will also facilitate transactional history download.
The electronic credit card may generate its unique transaction identifier number, which may be either in synchronisation with the transfer station link to a remote site system control function. The transaction station may be an Internet site with this capability.
The electronic credit card financial limit can be verified by the transaction station with a link to a remote site system. This will prevent the electronic credit card from generating further transactions once the financial limit is reached. The funds limiting function is optional and may be activated by either the financial institution issuing the electronic credit card or by the holder to cross-check and either alert him or her of his or her account balance. The electronic credit card may transact electronic cash which can be used as a currency exchange device. A traveller going abroad can choose to have a set amount for a specific currency of a particular country that he or she is visiting. The electronic credit card may be incorporated into another electronic device or piece of equipment, for example it may have been incorporated in a mobile phone.
An audio transducer is used to confirm a successful process of successful verification of the user and may also be used to provide communication over a telephone network.
A self-contained timer deactivates the user verification after a predetermined lapsed amount of time by deactivating an authorization code. This feature eliminates a stolen electronic credit card from being used when the user identification has already been verified.
The electronic credit card keypads may be made from flexible board membrane, rubber and/or plastics material to provide durability and in a slim size. The keypad may be designed with round, square or other shaped buttons.
The electronic credit card can store more than one credit card/debit card accounts. These can be cards distributed from different financial institutions, organisations or companies. The electronic credit card can retain amounts of transactions conducted by the user, with information regarding his or her financial balance in relation to the account limit. This may be available for one or more credit card accounts.
Modifications and variations may be made to the present invention without departing from the basic inventive concepts. The nature of such modifications and variations are to be determined within the scope of the present invention as defined by the foregoing description and appended claims.
