Cross Reference to related Co-Pending Applications

This application claims the benefit of U.S. provisional application Serial No. 61594474 filed on February 3, 2012 and entitled SYSTEM AND METHOD FOR A SECURE CARDHOLDER LOAD AND STORAGE DEVICE, which is commonly assigned and the contents of which are expressly incorporated herein by reference. This application is a continuation in part of U.S. application Serial No. 13080047 filed on April 5, 2011 and entitled SYSTEM AND METHOD FOR CHECKOUT AND CUSTOMER DATA CAPTURE IN COMMERCE APPLICATIONS, which is commonly assigned and the contents of which are expressly incorporated herein by reference.

Field of the Invention

The present invention relates to a system and a method for a secure cardholder load and storage device that interfaces with a consumer remote device for capturing and transmitting payment card present data to merchants via merchant point of sale (POS) checkout systems, in the physical and virtual environments.

Background of the Invention

Near Field Communication (NFC) chips have been embedded in some mobile phones directly or via SD Memory Cards, or SIM Cards, and are used by companies such as Google or ISIS as digital wallets for storing secure cardholder information. These NFC chip based digital wallets are used in contactless payment transactions with point-of-sale (POS) devices that support such contactless transactions. Mobile phones with the embedded NFC chip based digital wallets have several problems with complexity, applicability, security, and flexibility, among others. One of these problems is that not all phones have an embedded NFC chip. This severely limits penetration of this mobile wallet solution to the public. Furthermore, the process for loading the NFC chip's secure element with the payment card data is complex to implement and carry out. In particular, data loading onto the NFC chip's secure element over the air has security issues that need to be addressed. These security issues exist at every point the cardholder data touches in order to get from an issuer to the secure element. Currently, a Trusted Security Manager (TSM) is required for loading personal payment credentials onto the NFC chip's secure element over the air. Payment card issuers have to sign up for such a TSM service and to pay for such services. Furthermore, there are various technical complexities in order to make the loading process work smoothly, especially when some part of the loading process fails in the middle. Furthermore, not all standards have been worked out, and there are multiple competing parties making it more difficult to become ubiquitous. The applications and value proposition for the consumers and for the merchants are limited if the only purpose is to allow NFC to be used for contactless payment in POS devices. More value has to be created for the consumers and merchants and the process has to be much less complex for issuers, and consumers to load their digital wallet, and for them to use it with merchants. Summary of the Invention

The present invention relates to a system and a method for a secure cardholder storage and transport device that works in conjunction with an application in order to capture payment card data, to securely store the captured payment card data, and to transmit card present data to merchants via merchant point-of-sale (POS) checkout systems, both in the physical and virtual environments. The system provides convenient buying experience for buyers, and secure and informative transaction for sellers.

Detailed Description of the Invention

Referring to FIG. 1, the system 80 of the present invention includes a mobile card reader / card storage device (Secure Card Transporter (SCT)) 100 that interfaces with a remote communication device 150 via the audio jack 122 and/or USB port 124 of the device. System 80 also includes a secure mobile wallet application 130 and a payment checkout application 140. The secure mobile wallet application 130 initializes and unlocks the SCT 100 and the payment checkout application 140 interacts with the SCT and accepts card present payment data or tokens from the SCT 100. The remote communication device may be a Smartphone, a tablet, or a PC, among others.

The SCT device 100 includes a micro processor 102, an NFC chip 106, a battery 116, a charging circuit 118, a magnetic stripe reader 104, a contact chip card reader 108, a contactless stripe reader 109, a 3.5mm audio jack interface 112, and a micro USB port/jack interface 114. Microprocessor 102 handles security and communications with the remote communication device 150. The NFC chip 106 is used for storing cardholder data in its secure element. The NFC chip 106 may also be used as a tag or contactless card, that is read by POS with contactless capabilities. The NFC chip 106 may also be used for reading other contactless cards in certain circumstances, and for transmitting card data to other SCT devices in a peer-to-peer mode. The magnetic stripe reader 104 is used for loading payment card data onto the secure element of the NFC chip 106 and for capturing card track data for a POS application or checkout application on the host remote communication device 150. The remote communication device 150 includes the mobile wallet application 130, a checkout application 140, audio jack port 122, USB port 124, a screen 126 and a keyboard 128. The mobile wallet application 130 on the host device 150 interacts with the SCT 100 in order to control and provide different modes of operation including Card Emulation Mode, Card Load Mode, and Card Read Mode.

To provide better security in usage of the SCT, each SCT device is initially open to be paired with the user's wallet account, and only with one account. Once it is paired, it must be unlocked by the wallet application to change modes and parameters on the SCT. The SCT can store cardholder data by either an initial load at manufacturing, or by an over the air load after setting up a wallet account paired with the SCT, or by the consumer directly loading their SCT via the wallet application on his/her remote communication device by swiping or keying their card information into both the secure element and the user's wallet account. Wallet user is defined as a person that has setup a digital wallet account on the cloud, and has initialized a mobile wallet application on their phone.

Card Emulation Mode: Here a wallet user who enters his application with a PIN can change the modes of how the NFC chip allows the cards in the secure element to be selected and discovered for use by POS card readers. Wallet user can choose the default card being used, user can set the SCT to allow for the default card to be exposed to discovery by contactless readers, or exposed only for a limited time upon entering a PIN to unlock the default card in the mobile wallet app.

Card Load Mode: Upon initializing the SCT, the wallet user can use the Wallet Application to load his/her cards into both the digital wallet in the cloud with permanent account number (PAN) data (not track data), and it can store the track data in an encrypted manner into the secure element of the NFC chip in the SCT for use later in a secure checkout from a merchant. The Top-of-Wallet (default) card is usually the first card loaded, but can be changed by the user. The encrypted track data is not useful to hackers that obtain it by whatever means, and can only be decrypted by a corresponding payment server upon checkout and is not useful otherwise. Contactless Track Data can also be stored in the secure element of the NFC chip at manufacturing or key injection facility, or loaded by the consumer by converting his/her magnetic stripe track data into a contactless track data via the wallet application using special procedure.

Card Read Mode: This mode allows the stored encrypted track data to be retrieved and sent to a corresponding checkout application that accepts card present remote checkout. The reader can also be used by a POS application on the host device to accept payments like any merchant application, by interacting with the Swiper or NFC contactless reader to obtain cardholder data from magstripe cards or from contactless cards.

The unique elements of the invention include the following: 1) the NFC storage mechanism is connected via a ubiquitous audio jack; 2) the loading method to the NFC is much more simple when leveraging a separate magstripe card reader; 3) ability to store not just contactless credentials in the secure element but also regular magnetic stripe track data to be used later in checkout scenarios; 4) ability to change modes of emulation via wallet app as described above; 5) a personal NFC device is combined with a magnetic stripe reader so that the reader can be turned into a personal POS to pay for goods remotely, or turned into a merchant POS for acceptance of cards from other buyers or consumers.
