## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of prior U.S. patent application Ser. No. 14/263,013, filed on Apr. 28, 2014, which is hereby incorporated by reference herein in its entirety.


FIELD OF TECHNOLOGY
This invention relates to real time mutable credit card information.
BACKGROUND OF THE DISCLOSURE
Credit and debit card information may include a card number, a card security code, a card holder name, a card expiration date and/or any other pertinent information.
Credit and debit card information has been subject to many security breaches in recent years. Credit and debit card information may be stolen in many different ways. For example, this information can be stolen at an automatic teller machine (“ATM”) or in any other suitable location.
Card information theft can occur if someone places a skimming device on the ATM card reader which reads the information from the card's magnetic strip.
Card information can also be stolen at a retail location. This can occur if someone places a skimming device on the card reader at the retail location, which reads the card information from the card's magnetic strip. The skimming device may save the card information and/or may transmit the card information to a thief. The thief may then use the card information to make unauthorized purchases. In addition, there are many other ways that have not been described, in which card information may be stolen.
A card user may realize, at a later date, that his or her credit card information was stolen. The realization may occur when the card user receives his or her credit or debit card bill, and sees transactions that he or she did not execute and/or authorize. The card user may then contact the company which issued the card—e.g., the bank, or credit card company—to report fraud on his or her card.
The issuing company may decide to refund the user for the fraudulent transaction(s), and issue the user a new card. Issuance of a new card, including new card information, in addition to refunding a transaction, may be expensive for the company issuing the card.
In addition, if fraudulent activity occurs in a major retail store, the issuing card company may automatically send out new cards, with new card information, to any user who frequented the particular retail store in a specific time frame, e.g., a recent time frame. Sending new cards, with new card information, to millions of shoppers can be very costly for the company issuing the cards.
Therefore, it would be advantageous for a company issuing a card to have the ability to change the card information without sending new physical cards.
SUMMARY OF THE INVENTION
An apparatus for providing real time mutable credit card information is provided. The apparatus may include a smartcard. The smartcard may include a microprocessor chip, a button coupled to the microprocessor chip, a dynamic transaction authorization number and a Bluetooth low energy device (“BLE”) coupled to the microprocessor chip. The BLE may be configured to transmit, in response to depression of the button, an instruction to a smartphone for a request for a dynamic transaction authorization number. The BLE may also be configured to receive the dynamic transaction authorization number from the smartphone. The smartcard may also include a battery. The battery may be configured to power the BLE and microprocessor chip. The smartcard may also include memory. The memory may be configured to store the dynamic transaction authorization number. The smartcard may also include a dynamic magnetic strip. The dynamic magnetic strip may include a digital representation of the dynamic transaction authorization number.

DETAILED DESCRIPTION OF THE DISCLOSURE
Apparatus and methods for real time mutable credit card information are provided. Such apparatus and methods may include smartcards and computer hardware and software that are compatible with the internet—i.e., the worldwide web.
The smartcard apparatus may include a microprocessor chip. The apparatus may also include a button, a dynamic transaction authorization number, and a BLE. The BLE may be configured to transmit an instruction to a smartphone.
In some embodiments, the instruction may include a request for a dynamic transaction authorization number.
A request for a new dynamic transaction authorization number may be generated by the smartcard in response to the button being depressed. In certain embodiments, a user may depress the button on the card whenever he or she wishes. Some users may depress the button and request a new dynamic transaction authorization number after every transaction that he or she executes. Other users may depress the button and request a new dynamic transaction authorization number one time per month. Other user may never choose to depress the button and request a new dynamic transaction authorization number.
The BLE may also be configured to receive the dynamic transaction authorization number from a smartphone. The smartcard apparatus may also include a battery. The battery inside the smartcard may be a long-life battery which may have the ability to last for 6 years or more. During the periods of inactivity, the smartcard apparatus may also have the ability to enter sleep mode. This sleep mode capability may prolong the life of the smartcard's internal battery. The battery may be configured to power the BLE. The battery may also be configured to power the microprocessor chip. The smartcard apparatus may also include memory. The memory may be configured to store the dynamic transaction authorization number. The memory may also be configured to store other information: for example, the name of the user, the address of the user, the telephone number of the user and the current time.
The smartcard apparatus may also include a dynamic magnetic strip. The dynamic magnetic strip may include a digital representation of the dynamic transaction authorization number. The dynamic magnetic strip may have the ability to change the digital representation based on the dynamic transaction authorization number.
The smartcard apparatus may also be configured to communicate with an application on a smartphone. The smartcard may be configured to receive information from an administrative device via the application on the smartphone. The smartcard may be also be configured to transmit information to the administrative database network via the application on the smartphone.
The communication of the smartcard with the administrative database network via the smartphone application may allow the user to use the smartcard immediately after depressing the button. Only a short time—e.g., substantially less than a second—after depressing the button, the smartcard's dynamic magnetic strip may already contain the digital representation of the new dynamic transaction authorization number.
In addition, the administrative database network has preferably saved the information relating to the previous dynamic transaction authorization number and the window of time in which the specific dynamic transaction authorization number was valid. The administrative database network has the information for the window of time in which the dynamic transaction authorization number was valid, because the administrative database network saves the timestamp of each button depression.
When a request for a new dynamic transaction authorization number is received, the administrative database network retrieves the dynamic transaction authorization number which has been active until the request, the current timestamp, and the timestamp of the previous button depression. The administrative database network then saves the window of time (the previous timestamp to the current timestamp) and the dynamic transaction authorization number.
The window of time is then used when administrative database network authorizes a transaction. At the point of sale, the merchant may transmit the current dynamic transaction authorization number and the timestamp of the card swipe. The administrative database network may receive the dynamic transaction authorization number and the timestamp of the card swipe. The administrative database network may verify that the transmitted timestamp is included in the window of time in which the specific dynamic transaction authorization number is valid.
The smartcard apparatus may be configured to receive a transmission of the dynamic transaction authorization number from the smartphone.
In response to the depression of the button, the smartcard may also be configured to record the transmitted digital representation and a timestamp of the button depression. In this embodiment, the smartcard may transmit the timestamp of the button depression to the administrative database network together with the request for a new dynamic transaction authorization number. This may alleviate the need for the administrative database network to calculate the current timestamp of the request. This is because the timestamp was received together with the request.
The smartcard may also be configured to receive a new dynamic transaction authorization number from the administrative network via the application on the smartphone.
The smartcard may also be configured change the digital representation on the dynamic magnetic strip on the smartcard in response to receiving a new dynamic transaction number from the smartphone.
The smartcard may also be configured to receive a new dynamic transaction authorization number from the administrative network via the application on the smartphone in response to the administrative network receiving information pertaining to a security threat which may affect the security of the smartcard. The security threat information may be independent of a button depression the user.
The administrative database network may receive information pertaining to a security threat. The administrative database network may then perform a series of algorithms, which may determine which users may be affected by the security threat. For example, if a specific retail store by the fictitious name, SUPER'S SUPERMARKET, discovers skimming devices on its card readers, it may, in turn, notify the administrative database network regarding a security threat at SUPER'S SUPERMARKET.
The administrative database network may then perform a series of algorithms, which determine any credit or debit card holder who used his or her credit or debit card at SUPER'S SUPERMARKET within 60 days of the skimming attack. The administrative database network may then transmit new dynamic transaction authorization numbers to the smartcards, via the smartphone applications, of those users which the administrative database network's algorithms determine to be possibly subject to a security threat.
The microprocessor chip located in the smartcard may also be configured to change the digital representation on the dynamic magnetic strip in response to receiving a new digital representation from the smartphone.
The microprocessor chip located in the smartcard may also be configured to save the digital representation in memory. The microprocessor chip may also be configured to write the dynamic transaction authorization number to the dynamic magnetic strip as a new digital representation.
In some embodiments, the smartcard may receive a future timestamp in addition to a new dynamic transaction authorization number. This combination of a future timestamp and a new dynamic transaction authorization number may be understood by the smartcard as an instruction to save the new dynamic transaction authorization number to memory, but not to write the digital representation to the dynamic magnetic strip, until the point in time of the future timestamp.
In other embodiments, the microprocessor chip may also be configured to save the digital representation directly to the magnetic strip.
In yet other embodiments, the dynamic magnetic strip may be configured to be the memory of the smartcard.
In yet other embodiments, the instruction transmitted from the smartcard to the smartphone may include a request for a dynamic transaction authorization number and a new PIN number. A PIN number is sometimes used in association with a credit or debit card.
In these embodiments, a user is required to swipe his or her credit or debit card at a point of sale or ATM machine, and then the user is required to enter a four digit PIN number. The PIN number is conventionally not written nor saved on the card itself; rather the user must remember his or her PIN number. The use of a PIN number decreases the ability for a thief to obtain usage of stolen credit or debit card information, because the thief may obtain all of the information which is available on the card itself, but may not be able to obtain the PIN number which only the user knows.
A user may wish to change his or her PIN number if he or she feels that the security of the PIN number has been compromised. A user may wish to change his or her pin when, for example, a user sees an unscrupulous person viewing the PIN pad during a transaction that the user executed at an ATM machine. In this embodiment, the user may have the ability to view the new PIN number on an application on his or her smartphone.
