## Background
BACKGROUND
Technical Field
Embodiments generally relate to authorizing transactions. More particularly, embodiments relate to the use of virtual transaction cards to authorize transactions in mobile environments.
Discussion
Conventionally, in order to authorize another individual to make transactions with respect to a credit card account, either the account holder's card may be given to the other individual or the other individual may be issued a credit card with his or her name on it. Such an approach may present challenges with regard to controlling spending, particularly when the other individual is a teenager, adolescent, etc. While an alternative approach may be to purchase a gift card for the other individual, certain challenges remain. For example, purchasing a gift card (e.g., via third party or point of sale terminal) may involve a separate transaction, which may be inconvenient and time consuming for the account holder. Moreover, traditional gift cards may be limited to controlling the maximum amount spent and/or particular retailer.



BRIEF DESCRIPTION OF THE DRAWINGS
The various advantages of the embodiments of the present invention will become apparent to one skilled in the art by reading the following specification and appended claims, and by referencing the following drawings, in which:
FIG. 1 is a block diagram of an example of an architecture to authorize transactions according to an embodiment;
FIG. 2 is a flowchart of an example of a method of authorizing transactions according to an embodiment; and
FIG. 3 is a block diagram of a computing system according to an embodiment.



DETAILED DESCRIPTION
Turning now to FIG. 1, an architecture 10 to authorize transactions is shown. Generally, an account holder/subscriber 12 may have a credit and/or debit card account that enables the subscriber 12 to make purchases at retail locations, on web sites, etc., without the need for cash in order to complete the transactions. In the illustrated example, the subscriber 12 may use one or more devices 14 to issue a virtual transaction card to a mobile device 18 associated with a delegate 16, wherein the delegate 16 may use the virtual transaction card to make one or more purchases at a point of sale terminal 20, web site, or other commercial transaction location. In one example, the devices 14 include “mobile wallet” functionality that enables the subscriber 12 to conduct financial transactions in a secure environment on the devices 14. Of particular note is that the subscriber 12 may generate the virtual transaction card without involving third parties or point of sale terminals. For example, the illustrated devices 14 execute secure logic that is able to set the value of the virtual transaction card as well as one or more mobile usage constraints, without conducting a separate transaction, wherein the virtual transaction card may be delivered to the mobile device 18 via a near field communications link 22 or other connection such as a network interface link. The card value may be a relatively small value (e.g., in relation to the amount of available credit in the account), which may enable the subscriber 12 to tightly control the purchases made by the delegate 16.
Moreover, the mobile usage constraints may provide even greater control over the purchases of the delegate 16, relative to conventional solutions. For example, the subscriber 12 may set a time bounded policy for the virtual transaction card, wherein if the time bounded policy is not satisfied, the card is deemed invalid at the time of the attempted purchase. Thus, if the subscriber 12 stipulates that the virtual transaction card must be used within the next twenty-four hours, if the delegate 16 attempts to use the card to make a purchase after the twenty-four hour period has expired, the attempted transaction may be denied at, for example, the point of sale terminal 20.
Additionally, the subscriber 12 may set a location bounded policy for the virtual transaction card, wherein if the location bounded policy is not satisfied, the card is invalid. Thus, if the subscriber 12 stipulates that the virtual transaction card must be used within a particular geographic radius, at a particular store, or on a particular web site, if the delegate 16 attempts to make a purchase at a different location or web site, the attempted transaction may be denied at, for example, the point of sale terminal 20. The location bounded policy may also indicate that a particular store or web site is prohibited, wherein if the delegate 16 attempts to make a purchase at the prohibited store or web site, the attempted transaction may be denied. Other mobile usage constraints such as transaction type policies (e.g., genre, type of product or service), number of transactions, and so forth, may also be used.
Indeed, the mobile usage constraints could also define more advanced policies for the delegate 16 such as 1) setting “X” number of additional pre-paid cards that may be generated through the delegate's virtual transaction card (e.g., additional card policy), 2) eliminating user ID/authentication checks for such pre-paid cards while linking the identification information of the delegate's virtual transaction card to the subscriber's card (e.g., authentication policy), 3) digitally linking pre-approved information (e.g., subscriber's last four social security number digits) to the delegate's mobile wallet, wherein the linked information can be associated with the delegate's virtual transaction card when needed, 4) preventing the generation of new virtual transaction cards to the delegate until outstanding balances have been paid, and so forth.
In order to facilitate the management of the virtual transaction cards, parameters of the generated virtual transaction cards may be transmitted to a rule management module 26 in a cloud computing infrastructure 24, wherein the management module may be responsible for aggregating and maintaining all rules associated with a specific account, and reporting (e.g., via emit, text or other mode of communication) the activities of the delegate 16 to the subscriber 12. Of particular note, however, is that the devices 14 may generate the virtual transaction cards and distribute them to their respective delegates without conducting a financial transaction, authorization, etc., with regard to the management module 26 or other payment system component. Rather, the illustrated management module 26 merely provides the virtual card information (e.g., card values, mobile usage constraints) needed to conduct real-time approval of purchase requests at product and/or service providers such as, for example, the point of sale terminal 20.
In this regard, the point of sale terminal 20, may also include a rule module (not shown) that receives card information entered by the user and verifies the satisfaction of the appropriate policies/constraints with the management module 26 in real-time. The point of sale terminal 20 may also send transaction notifications to the subscriber 12. Alternatively, the mobile device 18 of the delegate 16 may be configured to run an account management application that provides transaction notifications to the subscriber 12.
FIG. 2 shows a method 28 of authorizing transactions. The method 28 may be implemented as a set of executable logic instructions stored in at least one machine- or computer-readable storage medium such as random access memory (RAM), read only memory (ROM), programmable ROM (PROM), flash memory, firmware, microcode, etc., in configurable logic such as, for example, programmable logic arrays (PLAs), field programmable gate arrays (FPGAs), complex programmable logic devices (CPLDs), in fixed-functionality hardware using circuit technology such as, for example, application specific integrated circuit (ASIC), complementary metal oxide semiconductor (CMOS) or transistor-transistor logic (TTL) technology, or any combination thereof. For example, computer program code to carry out operations shown in the method 28 may be written in any combination of one or more programming languages, including an object oriented programming language such as C++ or the like and conventional procedural programming languages, such as the “C” programming language or similar programming languages. Moreover, various aspects of the method 28 could be implemented as embedded logic of a processor using any of the aforementioned circuit technologies.
Illustrated processing block 30 provides for receiving user input via a subscriber mobile device having a mobile wallet capability, wherein block 32 may involve identifying a card value and one or more mobile usage constraints based on the user input. Thus, the user input may be used to set policies for an expiration time, a location, a card value, and so forth, in the illustrated example. A virtual transaction card may be generated based on the card value and mobile usage constraints, and sent to a delegate mobile device at block 34. In one example, a secure processing element on a subscriber mobile device is used to generate and send the virtual transaction card, wherein the card may be transmitted via a near field communications (NFC) module, network interface, and so forth. Additionally, illustrated block 36 transmits the virtual to transaction card parameters to a payment network (e.g., Euro, Mastercard, Visa/EMV) component such as, for example, the rule management module 26 (FIG. 1), already discussed. Block 36 may involve retrieving encryption information (e.g., private keys, digital signatures) from a secure storage element of a subscriber mobile device, and using the encryption information to transmit the card value and the mobile usage constraints to the payment network component.
The virtual transaction card parameters may be received on the delegate mobile device at block 38, wherein illustrated block 40 detects one or more purchase attempts. The purchase(s) may be verified against the card parameters at block 42 by, for example, transmitting an authorization request to a cloud based rule management module such as the rule management module 26 (FIG. 1), already discussed. Additionally, any appropriate rule based actions (e.g., notifications, approvals, denials) may be taken.
FIG. 3 shows a computing platform/system 46 that may be part of a mobile device having computing functionality (e.g., personal digital assistant/PDA, laptop, desktop, smart tablet), communications functionality (e.g., wireless smart phone), imaging functionality, media playing functionality (e.g., smart television/TV), or any combination thereof (e.g., mobile Internet device/MID). In the illustrated example, the system 46 includes a central processing unit (CPU) 48, an integrated memory controller (IMC) 50, a platform controller hub (PCH) 52, system memory 54, a network controller (e.g., network interface card) 56, non-volatile memory (NVM) 58, and one or more user interface (UI) devices 60. The CPU 48, which may include a core region with one or several processor cores 62, could alternatively communicate with an off-chip variation of the IMC 50, also known as a Northbridge, via a front side bus or a point-to-point fabric that interconnects each of the components in the system 46. In particular, the UI devices 60 may be capable of enabling a user to interact with and perceive the interface from the system 46.
The illustrated PCH 52, sometimes referred to as a Southbridge or South Complex of a chipset, functions as a host controller and communicates with the network controller 56, which could provide off-platform communication functionality for a wide variety of purposes such as, for example, cellular telephone (e.g., W-CDMA (UMTS), CDMA2000 (IS-856/IS-2000), etc.), WiFi (e.g., IEEE 802.11, 1999 Edition, LAN/MAN Wireless LANS), Bluetooth (e.g., IEEE 802.15.1-2005, Wireless Personal Area Networks), WiMax (e.g., IEEE 802.16-2004, LAN/MAN Broadband Wireless LANS), Global Positioning System (GPS), spread spectrum (e.g., 900 MHz), and other radio frequency (RF) telephony purposes. The illustrated system 46 also includes a near field communications module 64, which may further coordinate with the PCH 52 to facilitate off-platform communications using, for example, radio frequency identifier (RFID) technology. The PCH 52 may also include one or more wireless hardware circuit blocks to support such functionality.
The NVM 58 may include one or more hard disk drive (HDD) devices, solid state disk (SSD) NAND chips, etc., and may be used to provide high capacity data storage and/or a significant amount of parallelism. There may also be solutions that include NAND controllers implemented as separate ASIC controllers being connected to the PCH 52 on standard buses such as a Serial ATA (SATA, e.g., SATA Rev. 3.0 Specification, May 27, 2009, SATA International Organization/SATA-IO) bus, or a PCI Express Graphics (PEG, e.g., Peripheral Components Interconnect/PCI Express x16 Graphics 150W-ATX Specification 1.0, PCI Special Interest Group) bus. The NVM 58 could also be used as a USB (Universal Serial Bus, e.g., USB Specification 3.0, USB Implementers Forum) flash storage device.
The illustrated system 46 also includes a secure processing element 66 that runs an embedded operating system (OS) such as Java Card OpenPlatform (JCOPO) or SmartCafe OS from NXP Semiconductors, Eindhoven, The Netherlands. In one example, the embedded OS can be run securely without involving any host OS running on the CPU 48. The illustrated secure processing element 66 includes a card generation module 68 configured to generate a virtual transaction card based on a card value and one or more mobile usage constraints including a time bounded policy, wherein the virtual transaction card is to be invalid if the time bounded policy is not satisfied. Other policies such as a location bounded policy and transaction type policy may also be used. Of particular note is that the virtual transaction card may be generated without involving a third party or point of sale terminal.
The secure processing element 66 may also include a card distribution module 70 configured to transmit the virtual transaction card to a delegate mobile device. The virtual transaction card may be transmitted to the delegate mobile device via, for example, the near field communications module 64, the network controller 56, and so forth. The illustrated secure processing element 66 also includes a network identification module 72 configured to transmit the card value and the one or more mobile usage constraints to a payment network component. In one example, the network identification module 72 retrieves encryption information 74 from a secure storage element 76, and uses the encryption information 74 and the network controller 56 to communicate with the payment network component. The card value and one or more mobile usage constraints may be obtained from an account holder/subscriber 12 such as the subscriber 12 (FIG. 1) via the UI devices 60.
Thus, techniques described herein may enable credit/debit card owners to set spending limits for delegate card users, limit where the card can be used (e.g., by genre, brick and mortar store, location, web site, etc.), limit the number of transactions the delegate can make, monitor spending activity, approve individual expenses in real-time through a payment notification and approval process, receive information on how the delegate is attempting to use the owner's card, and so forth. The technology may be effectively used by either issuer banks or by EMV to enable users to generate small value transactions cards, pre-paid cards, or credit cards. In addition, the transaction card generating application may run in a secure element via a mobile wallet option. The mobile wallet option may also send messages to a payment network (such as EMV) and/or to an issuer bank either as encrypted SMS (short messaging service, text) message or an IP (Internet Protocol) connection message.
