20150347998
The present invention pertains to the field of personal interface devices, and more particularly to a personal interface device with improved security.
Personal devices are known that allow a user to store data in the device for the purpose of providing the data to external systems. For example, such personal devices include credit card consolidators that store multiple credit card numbers, and that allow a user to select one of the credit cards for making payment at a point of sale. A magnetic stripe emulator is used by such devices to provide the selected credit card number to a magnetic stripe reader.
While such devices allow multiple credit card numbers and related information to be stored, they present an increased risk from theft of the device, because they allow an unauthorized user can still bypass security measures. For example, if a PIN number is required by the device, an unauthorized user would be able to try various PIN numbers until one was found that worked. Such devices also provide limited additional functionality.
In accordance with the present invention, a personal interface device and system for using the personal interface device are provided that overcome known problems with personal interface devices.
In particular, a personal interface device is provided that allows a personal identification device such as a driver's license to be used with the personal interface device.
In accordance with an exemplary embodiment of the present invention, a personal device is provided. The personal device includes an identification verification system that receives first identification data from a physical identification device, such as by inserting a driver's license into a card reader that is adapted to receive a driver's license. Second identification data such as a PIN number is also received. Payment authorization data or other suitable data is generated if the driver's license corresponds to the PIN. A payment selection system or other suitable system receives the payment authorization data and displays one or more payment accounts for selection by a user. Where a payment selection system is used, the payment selection system transmits payment account data to a point-of-sale system.
The present invention provides many important technical advantages. One important technical advantage of the present invention is a personal device that requires two types of identification to operate, including a physical identification device such as a driver's license that can be used to verify the identity of the user. The present invention thus helps to prevent fraud.
Those skilled in the art will further appreciate the advantages and superior features of the invention together with other important aspects thereof on reading the detailed description that follows in conjunction with the drawings.
In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals, respectively. The drawing figures might not be to scale, and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.
Personal devices 100A and 100B include device control system 102. Personal devices 100A and 100B can each be a personal digital assistant, a palmtop computer, a handheld computer, a cell phone, or other suitable devices. Device control system 102 can be implemented in hardware, software, or a suitable combination of hardware and software, and can be one or more hardware systems, or one or more software systems operating on a suitable processing platform. As used herein, a hardware system can include discrete semiconductor devices, an application-specific integrated circuit, a field programmable gate array or other suitable devices. A software system can include one or more objects, agents, threads, lines of code, subroutines, separate software applications, user-readable (source) code, machine-readable (object) code, two or more lines of code in two or more corresponding software applications, databases, or other suitable software architectures. In one exemplary embodiment, a software system can include one or more lines of code in a general purpose software application, such as an operating system, and one or more lines of code in a specific purpose software application.
Personal devices 100A and 100B include an identification device slot 104. In one exemplary embodiment, as shown on personal device 100A, the identification device slot 104 is incorporated into the housing of the personal device 100A. In another exemplary embodiment, a cradle 106 or other suitable devices can be used to provide the identification device slot 104 for use in conjunction with personal device 100B. In this exemplary embodiment, a user can carry cradle 106 as an integral part of personal device 100B, such as where cradle 106 is a wireless device, a protective device, or serves other purposes. In another exemplary embodiment, cradle 106 can be provided at a point of sale, and can be activated in conjunction with personal device 100B when a purchase is made, such that the user provides the identification device to identification device slot 104 and places personal device 100b in cradle 106 in order to proceed with the transaction.
Payment control system 192 allows the user to select one or more payment accounts for payment of a transaction. In one exemplary embodiment, the user inserts the identification device into identification device slot 104, and device control system 102 then generates a query for the user. The query can include a request to enter a PIN number or other suitable second identification data. In this manner, device control system 102 determines whether the first identification data from the identification device in identification device slot 104 corresponds to the identification data entered by the user in response to the query or in other suitable manners. Thus, if the personal device 100A or 100B is lost or misappropriated, it cannot be used to generate or transmit payment data without both of the personal device and knowledge of the user's second identification data.
In operation, a user takes personal device 100A or 100B to a store and initiates a purchase transaction. To provide payment data, the user then inserts an identification device into identification device slot 104 and enters second identification data in response to a query or other prompt from device control system 102. After device control system 102 determines that the identification device corresponds to the second identification data, device control system 102 provides the payment data. For example, the payment data can include credit card data, debit card data, electronic funds transfer data, or other suitable data that is used to purchase the desired goods or services. Personal device 100A or 100B can provide the payment data to a point of sale terminal, through a wireless or wireline network or other suitable networks or communications media to a central controller, or in other suitable manners.
