Abstract

An embodiment includes a credit card device capable of generating a programmed magnetic field of alternating polarity based on a speed of a card swipe, and methods for constructing the device for the purpose of emulating a standard credit card. An apparatus is described to allow said device to emulate behavior of a credit card when used in electronic credit card readers. Additionally methods are described to allow user control of said device for the purpose of authorizing or controlling use of said device in the application of credit, debit and cash transactions, including cryptocurrency and card-to-card transactions. Methods are also described for generating a limited-duration credit card number when performing a transaction for the purpose of creating a limited-use credit card number, which is limited in scope of use to a predetermined number of authorized transactions. Furthermore said device may interact with other similar devices in proximity for the purpose of funds or credit/debit transfers.

Claims

1. A credit card device comprising:

a near-field communication (NFC) unit;

a touch sensor array;

a display;

a motion rate detection array;

a memory, storing a user data and a currency amount; and

a processor operatively coupled to the NFC unit, the touch sensor array, the display, the motion rate detection array, and the memory; and

wherein the processor initiates a card-to-card transaction between two credit card devices by a detected proximity of a first credit card device and a second credit card device and an input of information by a first user via said touch sensor array, and wherein the card-to-card transaction comprises an exchange of stored currency and said user data between the first credit card device and the second credit card device via the NFC unit.

2. The credit card of claim 1, wherein the motion rate detection array comprises a set of motion rate detection units, wherein the set comprises:

a plurality of inductor coils and companion magnetic-field pickup coils;

an optical sensor array; and

a plurality of accelerometers, and wherein the detected proximity is determined from at least one of the set of motion rate detection units.

3. The credit card device of claim 2, wherein the plurality of accelerometers generate an indication of the detected proximity in response to a contact between the first and the second credit card devices.

4. The credit card device of claim 1, wherein the input of information by the first user comprises one or more of:

an introduction of a transaction-specific identifier;

a confirmation or a denial of an indicated transaction; and

a lock/unlock command determining operation of the first credit card device according to an input sequence or a gesture across the plurality of touch sensors.

5. The credit card device of claim 1, further comprising a real-time clock which generates a sequential parameter when the processor initiates a transaction, wherein the sequential parameter is combined with any of a user information, a transaction identifier, a user secret, and a credit card authority secret and the processor is operable to generate a limited-duration credit card number therefrom.

6. The credit card device of claim 5, wherein the limited-duration credit card number has a limited recurrence, and is limited in scope of use to a predetermined number of authorized transactions.

7. The credit card device of claim 5, wherein the display enables information to be displayed regarding the limited-duration credit card number, the time, a passcode, a sequence code, a currency amount, and other credit card transaction information of the user, a merchant, a bank or a credit card authority.

8. The credit card device of claim 5, wherein the card-to-card transaction comprises a cryptographic hash of the transaction unit, wherein the cryptographic hash is processed and stored by at least one of the first credit card device and the second credit card device.

9. The credit card device of claim 1, further comprising a USB connector for connection to a standard computing device.
