CROSS-REFERENCES TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 11/998,168, filed Nov. 28, 2007, entitled “Multifunction Removable Cover for Portable Payment Device,” for which is herein incorporated by reference in its entirety.


FIELD OF THE INVENTION
Aspects and embodiments of the present invention relate in general to methods and devices for conducting financial transactions. Certain aspects include multifunction removable covers for portable payment devices. Further aspects include multifunction removable covers configured as password token type portable payment devices. Further aspects include multifunction removable covers configured as radio frequency shields to prevent unintended data transmission.
BACKGROUND
The use of portable payment devices in financial transactions has seen a steady increase within the last few years. Currently, a variety of portable payment devices are commercially available. However, despite their initial popularity, one of the technical challenges which has limited the level of general acceptance of certain password token type portable payment devices is that several of these devices are dependent on a fixed internal power supply (e.g. battery) for sustained operations. This apparent limitation and the requirement for easy access to an internal power source renders some of these portable payment devices (e.g. credit cards) difficult to manufacture in a way that is in compliance with certain industry recognized manufacturing standards, such as, for example, International Standard Organization (ISO) standards; or in certain cases, the rigorous internal manufacturing standards of branded payment tokens.
Recently, the vulnerability of the static “user ID and password” during e-commerce and/or financial transactions has become increasingly apparent as identity theft and unauthorized access to private and confidential user data is increasingly prevalent. The traditional static “user ID and password” system is subject to security breach and/or password leakage during a variety of processes, including logon, password generation, storage and distribution. Current measures to enhance the security of the static “user ID and password” system include the use of one-time password systems that substitute the static password with a dynamic password. One-time passwords (OTPs), which may be generated randomly, automatically, and then displayed, typically can be used only once. They provide an additional level of security against breach of password security. However, certain technical challenges remain in delivering a one-time password in connection with the use of these password tokens as traditional one-time password systems are typically closed systems. Hence, the user may be inconvenienced with subscriptions to more than one service provider. Each service provider may also require a different token due to variations of individual service provider authentication servers. Further, some payment devices require a Personal Identification Number (PIN) to operate and the user must remember the PIN for each different device, which adds to the difficulty in implementation and possible reduced consumer usage.
Furthermore, if these initial hurdles are to be overcome and the usage of these portable payment devices become more prevalent, there is an additional need for the ability to prevent unintended radio frequency (RF) transmissions to protect user data when the RF-enabled password tokens are in transit while being delivered to the account holder or when the account holder is in an environment wherein the suspicion and/or the risk of security breach via unintended broadcast or signal capture is high.
Additionally, many account holders of portable payment devices are often unaware of the current account balance on their respective portable payment devices. While some issuer and acquirers mandate support for balance inquiries for some devices such as, for example, gift cards and incentive cards, such support is optional at merchants.

As used herein, portable payment devices and multifunction removable covers thereof provide an integrated apparatus for conducting electronic commerce and/or financial transactions. The transactions may include, for example, retail purchases, transit fares, access to venue fares, or online transactions.
In certain embodiments, portable payment devices are used in an electronic transaction (e.g., a point of service that is connected to a payment processing system during a transaction). The information from the payment device may be transmitted to an issuer during a retail payment transaction for purposes of authorizing the use of the payment device for that transaction. The issuer may review parameters of the transaction such as transaction amount, credit history, card authenticity, and other factors when determining whether or not to authorize or decline the transaction.
In general, an issuer validation (e.g., authorization) request message is created during an electronic transaction for goods and/or services at a Point Of Sale (POS) using a portable payment device. The issuer validation request message can be sent from the POS terminal located at a merchant to the merchant's acquirer, to a payment processing system, and then to an issuer. An “issuer validation request message” can include a request for issuer validation to conduct an electronic payment transaction. It may include one or more of an account holder's payment account number, currency code, sale amount, merchant transaction stamp, acceptor city, acceptor state/country, etc. An issuer validation request message may be protected using a secure encryption method to prevent data from being compromised.
As used herein, an electronic payment transaction may be authenticated if the consumer conducting the transaction is properly authorized and has sufficient funds or credit to conduct the transaction. Conversely, if there are insufficient funds or credit in the consumer's account, or if the consumer's portable payment device is reported as lost or stolen, then an electronic payment transaction may not be authorized.
As used herein, portable payment device according to some embodiments of the present invention may include payment device having vertical and horizontal dimensions of a standard credit card, e.g. about 21⁄8 inches by about 33⁄8 inches and a multifunction removable cover which extends over substantially the portable payment device. In some embodiments, the payment device-cover assembly may be thicker than a standard plastic credit card. In certain embodiments, a display panel (1004) extends over substantially the face of the multifunction removable cover.
In some aspects, a processor is provided in the cover device that is configured to display unique user associated data on the display panel and, in some embodiments, to control the magnetic encoder on the portable payment device to provide magnetic stripe information for the predetermined credit card, in response to user selection of the predetermined credit card via the user input device (1006 A-C).
In certain embodiments, multifunction removable cover for portable payment devices may include imprinting features, which may include, for example, user name; account number, including for example, 16 digit number in groups of four that is unique to the account holder.
In certain embodiments, the multifunction removable cover for portable payment devices may include a power source, including, for example, a battery 1020, fuel cell and/or photocell. In certain other embodiments, there is provided a multifunction removable cover for portable payment devices comprising an electrical contact, such an electrical contact may include, for example, those used in conventional “smart cards” or a Universal Serial Bus (USB) connector (3000).
In certain other embodiments, the multifunction removable cover for portable payment devices may include one or more user input devices, such as one or more soft keys that are incorporated into the flat panel display, a keypad, a keyboard, and/or other user input device.
In certain other embodiments, the multifunction removable cover for portable payment devices may include components and/or material for shielding undesired transmissions from the portable payment device, including, for example, transmissions mediated by a short range wireless transmitter/receiver, such as, for example, a Bluetooth, Wi-Fi and/or other short range radio transceiver; a Radio Frequency ID (RFID) receiver; an RFID transmitter; a cellular transceiver, including, for example, conventional cellular, Personal Communication System (PCS), wideband cellular, and/or other conventional cellular device; a bar code reader; a location system, such as a global positioning system (GPS) system.
In certain other embodiments, the multifunction removable cover for portable payment devices may include components and/or material, for example, one or more magnets, pins, pegs, extensions, pinholes, bored holes, for magnetically and/or non-magnetically aligning and/or coupling the multifunction removable cover to the portable payment devices. In certain aspects, the non-magnetic connection includes symmetrical alignment and/or fitment of the exemplary pins and/or pegs into similarly sized holes bored into the back of a portable payment device. It is understood by those familiar in the art that one or more magnets may be implemented.
In certain other embodiments, the multifunction removable cover for portable payment devices may include components and/or material for the prevention and/or blocking (blockers) undesired insertion of the multifunction removable cover-portable payment device assembly into magnetic/data reader, such as ATMs. Exemplary component/material for these blockers may include, for example, ABS, PVC plastic or any other compatible material to match the material of the payment device body. The blockers may also be placed and/or attached to the body of the payment device such that the height (e.g. thickness) of the blocker-payment device assembly effectively blocks insertion of the card into the transit unit of the ATM. In certain embodiments, the full height of the assembly (including the payment card, the multifunction card attachment, and the “ATM blocker” may be between, for example, about 3 mm and about 7 mm (FIGS. 11A-11B). In certain embodiments, the width of the blocker may be between about 0.25 cm and about 0.5 cm (FIGS. 11A-11B). In certain embodiments, the length of the blocker may be between about 2 cm and about 3 cm (FIGS. 11A-11B). In certain other embodiments, the dimensions of the blocker will vary within these tolerances depending on the specific application (display, RF shield, or USB configurations) in accordance with different sizes of the multifunction removable cover.
In certain other embodiments, the multifunction removable cover for portable payment devices may function in “Display Only and/or USB Connector mode.” In an exemplary configuration, the multifunction removable card cover is coupled magnetically and/or non-magnetically to the payment card. It is understood by one of skill in the art that modification of the payment device (e.g. payment card) may be performed within acceptable manufacturing parameters to accommodate the card-cover attachment mechanism. The card-cover and payment device assembly for use in the Display Only or the USB interface configuration may be further modified to be compatible with network infrastructure to manage the delivery and authentication of one-time passwords. As used herein, one-time password may include a password that changes after each login, or changes after a set time interval. Exemplary one time password may include mathematical-algorithm-based one-time passwords or time-synchronized one-time passwords.
In certain other embodiments, the multifunction removable cover for portable payment devices may function in the “display” only mode. The display card attaches to a standard payment card by magnetically or by positioning of the pegs (one or more) that are coupled to similarly sized holes bored into the back of a the payment card. The attachment substantially covers of the card while leaving the magnetic portion still exposed, so that the magnetic stripe may still be used for standard face-to-face transactions. In order to prevent accidental insertion into ATMs or other transport insertion mechanisms, the device may include one or more thicker elements to block unintentional card insertion. User associated data, including, for example, static and dynamic data, is displayed on the display panel in response to user input query or electronic communication/interrogation via contact making-elements on the payment device and the corresponding card cover when they are coupled.
In certain other embodiments, the multifunction removable cover for portable payment devices may include an external interface. Exemplary external interface may include, for example, a Universal Serial Bus (USB) or an Institute of Electrical and Electronics Engineers (IEEE) 1394 (Firewire) interface which may attach to a standard payment card. During user transaction, the user may insert the external interface into a computer in order to deliver one-time passwords for authentication. In certain embodiments, the external interface may facilitate programming dynamic card verification value (CVV) values in a chip on the card and delivered to a computer via the external interface. In certain embodiments, the multifunction removable covers with external interface attachments may or may not include the ATM insertion blockers.
In certain other embodiments, the multifunction removable cover for portable payment devices may function as a radio frequency (RF) shield to prevent undesired RF transmission once the payment card and the multifunction removable card-cover is accordingly positioned as a card-cover payment device assembly. Exemplary card-cover material, either as a constituent or as a surface coating, suitable for RF shielding may include, for example, aluminum, copper, titanium, or any other conductive element. An aluminum plate (or any other material deemed suitable to block the RF signal) may be so attached to a standard payWave (contactless-enabled) card by means described above. In certain desired configuration, the RF signal will only emanates out of the back of the card and thus blocks the undesired transmission of the private data. During mail delivery of the card to account holders, the multifunction removable card cover may be affixed to the payment card before it is mailed to the recipient to safeguard account the information. In certain embodiments, the cardholder may also choose to attach the cover when he/she does not want to transmit the data due to security concerns. The attachment may or may not have the ATM insertion blockers, as described above.
In certain embodiments, there is provided a system for conducting e-commerce and or financial transactions wherein the system comprises a multifunction removable cover for portable payment device and a terminal, which may include a card reader, which may be for example, any magnetic or optical card reader known in the art which is capable of reading information encoded in the magnetic stripe. The terminal may be similar in appearance to present day terminals, and may have a slot into which the various embodiments of the present invention will be inserted and slid past a card reader as in any present day card reading system.
The card reader will transmit this information to a network which identifies the user.
