       TECHNICAL FIELD  
         [0002]    The present invention relates to a system and method for supporting a plurality of applications on a payment terminal, more particularly, to providing payment and non-payment related services, such as e-services.  
         BACKGROUND  
         [0003]    Only a decade ago, a merchant could accept a single type of credit card and satisfy most customers. That has changed dramatically with the proliferation of card-based payment, payment-related and even non-payment options in the highly competitive retail marketplace. This has added significantly to the complexity of today&#39;s e-payment environment. Today, many customers carry a variety of cards, and they expect retailers to readily accept whichever card they choose for a given purchase. To compete effectively in this environment, merchants have offered a growing variety of credit and debit services, using various devices, such as a credit card swiper, a credit card authorization device, an electronic fund transfer point of sale device (EFTPOS) or a payment terminal or device, to enhance convenience and encourage customers to patronize their stores. Additionally, the payment device can be linked to the cash register.  
           [0004]    Merchants are always looking for new ways to enhance convenience and increase sales, while reducing costs. As payment terminals have become more powerful and sophisticated, they offer the potential to move into the mainstream of retail operations, such as providing an way to capitalize on untapped opportunities by supporting an array of value-added, non-payment applications. This changing environment has created a need for a single terminal capable of supporting multiple payment, payment-related and non-payment applications efficiently, securely and cost-effectively.  
           [0005]    Typically, the payment device accepts, processes and authorizes payment by various means, such as a credit card, debit card, smart card, check, etc. However, the payment device and its related services are not free, the merchant or retailer generally pays for the payment device itself and a percentage of each sale for processing each payment through the payment device. In other words, the payment device is a cost center to the retailer. Accordingly, it is desirable to offer other types of services on the payment device that the merchant can sell or offer to its customers, thereby minimizing the cost of operating the payment device.  
           [0006]    In a typical retail model or environment, the merchant has all of its merchandise on display to the consumer for a possible sale. The consumer comes to the retail store and selects various merchandise from the shelves for purchase. At the check-out counter, the merchant or merchant&#39;s cashier only totals the customer&#39;s purchases and accepts payment in either cash, check, credit card, debit card or other electronic methods. That is, the merchant utilizes the payment device to obtain authorization for customer&#39;s check, credit or debit card via a secured financial network. Therefore, it is desirable for merchants to convert the payment devices from cost centers to profit makers. For example, the payment devices of the present invention can be used to offer various e-services to customers, such as selling tickets for a concert, a sporting event, a movie, or any other event. That is, the merchant or customer accesses one of the e-services offered on the payment device of the present invention via an Internet connection and the merchant provides a printed ticket to the consumer after securing payment from the consumer via the normal financial connection. It is appreciated that the tickets can be printed directly from the payment device or from another device connected to the payment device.  
           [0007]    In the past, several smaller applications were linked together to become a single, larger piece of code within a traditional e-payment environment. However, because payment applications involve money, these applications must undergo a stringent certification process before they can be used. As a result, each time a change is made to any piece of a large monolithic application or a new application is added, the entire piece of code must be re-certified, at a significant cost to the developer and merchant. That is, even relatively minor changes to one of the programs or routines within a larger payment application can result in substantially increased development expenses and a slower time to market. Additionally, the stringent certification process adds a significant barrier to entry into this market. Accordingly, off-the-shelf terminals or PCs cannot simply be used to provide e-payment and non-payment services to the merchants.  
           [0008]    Also, there can also be significant performance penalties and unacceptably long download times with large, linked-together applications. This can tie up merchant&#39;s terminals, drive up telecommunications costs and greatly extend the time required to update all the terminals in a network. Finally, whenever a new function is added or changes are made to an existing large, monolithic application, there is an increased risk of corruption to the entire application code. This can create difficulties for banks, processors, developers, and merchants alike.  
         SUMMARY OF THE INVENTION  
         [0009]    The present system and method involves a multi-application terminal that comprises a memory for storing a plurality of payment and non-payment applications, a memory management unit for separating said applications in said memory. This permits said non-payment applications to exist side-by-side with said payment application without requiring additional certification. The multi-application terminal also comprises a processor for executing one or more applications, said memory management unit operable to assign a protected region within said memory to each application being executed by said processor. Said payment applications are operable to provide payment related services over a secured financial network and said non-payment applications operable are to provide non-payment related services over an open network.  
       
    
    
     BRIEF DESCRIPTION OF THE DRAWING  
       [0010]    The FIGURE is a block diagram showing the incorporation of the present invention within an e-payment environment.  
     
    
     DETAILED DESCRIPTION  
       [0011]    The present system and method utilizes multi-application software and/or hardware architecture to support both payment and non-payment related services, such as e-services.  
         [0012]    That is, one application can relate to the currently available financial products or services on the current payment terminals via a secure financial connection, such as processing and authorizing payments via credit cards, debit cards, checks, etc. The other applications can relate to various e-services, i.e., electronic products and services, that can be provided over the Internet, i.e., TCP/IP connection. In accordance with an aspect of the present invention, the payment terminal or device can be POS terminal, kiosk or vending machine.  
         [0013]    In accordance with an embodiment of the present invention, the system and method utilizes a hardware/software application separation mechanism that permits applications to safely exist side-by-side without corrupting one another. This advantageously makes it easier and faster to add, modify or download applications. Additionally, since individual applications can remain physically separate and not be linked into a single piece of code, no additional certifications are required for an existing application when adding or changing a payment-related or non-payment application. Further, this enables the developers or merchants to perform partial downloads of the new applications or required functions, rather than a large, monolithic piece of code, thereby saving substantial amounts of time and money, and minimizing inconvenience to a merchant&#39;s customers.  
         [0014]    In accordance with another embodiment of the present invention, the system and method enables a consumer to access the POS terminal, kiosk, payment device, and/or peripheral device, i.e., a publicly accessible device, using a private hand-held or portable device, such as a cell phone, beeper, two-way radio, smart phone, communicator, personal digital assistant (PDA), etc. That is, the consumer can use his/her private mobile appliance to browse through various content resident or accessible through the POS terminal, kiosk or payment device.  
         [0015]    In accordance with a further embodiment of the present invention, the system and method further enables the consumer to access various network servers and Internet web sites to purchase goods and/or services via the POS terminal, kiosk, payment device, etc. using his/her private mobile appliance. The e-service provider can also communicate with the merchant and/or the consumer via the POS terminal. For example, the e-service provider can send an electronic confirmation, receipt and the like.  
         [0016]    The present invention is readily implemented by presently available communication apparatus and electronic components. The invention finds ready application in virtually all commercial communication networks, including but not limited to a telephone network, a wireless network, a local area network (LAN), a wide area network (WAN), intranet, world wide web (Internet), and a wired cable transmission system.  
         [0017]    The FIGURE shows system  10  having multi-application terminal or e-services dispenser  100  supports a multi-application e-payment environment, thereby permitting merchants to securely run multiple payment, payment-related and non-payment applications created by different developers on the same platform. In accordance with an embodiment of the present invention, the multi-application terminal utilizes a hardware/software approach that enables various applications to safely exist side-by-side without corrupting one another.  
         [0018]    Preferably, multi-application terminal  100  includes custom-designed application specific integrated circuit (ASIC)  110  to run the various payment and non-payment related applications, memory management unit (MMU) chip  120  that provides physical separation for all applications in memory  130 , assigning protected regions within the multi-application terminal&#39;s memory for various applications running on the multi-application terminal at any given time. MMU  120  checks to determine whether any operations are inadvertently or intentionally trying to access memory outside of their allocated space. If it is determined that any application is attempting access memory outside its allocated space, MMU  120  can immediately stop the task or shut down the system before other applications are corrupted. This advantageously makes it easier and faster to add, modify or download applications. Additionally, since individual applications can remain physically separate and not be linked into a single piece of code, no additional certifications are required for an existing application when adding or changing a payment-related or non-payment application. Further, this enables the developers or merchants to perform partial downloads of the new applications or required functions, rather than a large, monolithic piece of code, thereby saving substantial amounts of time and money, and minimizing inconvenience to a merchant&#39;s customers. It is appreciated that the information between various applications can be shared using libraries and a common application program interface (API).  
         [0019]    In accordance with another embodiment of the present invention, multi-application terminal  100  comprises public key infrastructure (PKI) based software application  140  for authenticating files to prevent the execution of unauthorized software on multi-application terminal  100 . This advantageously minimizes the possibility of unauthorized files, such as non-supported software, running on multi-application terminal  100  and interfering or corrupting other applications. In accordance an aspect of the present invention, for software application to be authenticated on multi-application terminal  100 , the file is digitally “signed” by an authorized party.  
         [0020]    Accordingly, multi-application terminal  100  of the present invention is simply more than a credit card swiper, wherein either the merchant or customer swipes the card to authorize payment of the purchased product or services. The multi-application terminal not only supports financial applications via connection to back office control system  400  over a secure network (wireless or wire line) controlled by the financial institutions, but can be used to access e-services over an open network (wireless or wire line), such as the Internet via server(s)  300 .  
         [0021]    In accordance with an embodiment of the present invention, the multi-application terminal of the present invention has payment applications to process various electronic payments, i.e., credit card authorization, check authorization, etc., and other various applications to support various e-services, such as e-reservation services wherein the consumer can make reservations for a restaurant, e-takeout services wherein the consumer can order food for takeout and/or delivery, e-ticketing services wherein the consumer can purchase tickets for a concert, a sporting event, a movie, etc. Also, it can be used to purchase CDs, DVDs, wherein the desired movie, song, or album is downloaded onto a CD or DVD, electronic books, pre-paid telephone cards, and the like.  
         [0022]    Continuing in the FIGURE, there is illustrated an example of how the e-services dispenser or multi-application terminal  100  operates in a retail environment. The consumer accesses multi-application terminal  100  using his/her mobile or portable appliance  200 , such as a cell phone, personal digital assistant (PDA), beeper, or digital device via a wireless connection. The wireless connection can be established using any known techniques, including but not limited to wireless application protocol (WAP), shared wireless access protocol, wireless LAN or WLAN, IrDA, bluetooth, PAN, etc. Bluetooth is a short-range radio technology aimed at simplifying communications among net devices and between devices and the Internet. IrDa is short for Infrared Data Association, a group of device manufacturers that developed a standard for transmitting data via infrared light waves. Personal Area Network (PAN) is an IBM technology based on the electric-field transmission medium that allows individuals to exchange data with a simple touch or grasp. Multi-application terminal  100  is connected on one or more back end servers  300  to provide requested e-services, contents, etc. over the intranet or Internet. The multi-application terminal can be connected to back end server(s)  300  over a wired or wireless connection.  
         [0023]    The consumer can access one or more servers  300  to purchase various goods and/or services from various e-service providers, such as a pizza store, restaurant, ticketing agency, etc. For example, the consumer can order pizza from a pizza store, i.e., e-service provider, using multi-application terminal  100 . Using portable appliance  200 , the consumer access server  300  associated with the appropriate pizza store via multi-application terminal  100  to order the pizza. Preferably, portable appliance  200  can also transmit consumer information to the e-service provider or server  300 , such as telephone number, delivery address, delivery time, etc. Alternatively, the consumer can use the multi-application terminal  100  to access his/her portal containing his/her personal information, i.e., address, preferred payment method, telephone number, payment history, order history, preferred e-service provider, links to his/her favorite sites, etc. Upon receiving and/or processing the order, the e-service provider can transmit an electronic confirmation and/or receipt of the order to the merchant (i.e., multi-application terminal  100 ) and/or the consumer (i.e., portable appliance  200 ). It is appreciated that these various electronic information can be “beamed” to portable appliance  200  from multi-application terminal  100  over the wireless connection. Additionally, the merchant or the consumer can authorize payment for the order using multi-application terminal  100 . It is appreciated that since the consumer, merchant and e-service provider are electronically connected, information (i.e., consumer data) stored or contained in various devices, such as portable appliance  200 , multi-application terminal  100  and server  300 , can be synchronized as described in commonly assigned, co-pending U.S. patent application Ser. No. [Attorney Docket No. 10013330-1], entitled “HOT SYNC THROUGH POS TERMINAL,” the disclosure of which is hereby incorporated herein be reference in it&#39;s entirety.  
         [0024]    Alternatively, the merchant can use portable appliance  200  to manage and maintain multi-application terminals  100 , such as downloading records, uploading new applications, etc.  
         [0025]    The inventive system and method enables a consumer to access a publicly accessible kiosk or payment device with a private hand-held or portable device or appliance, such as a cell phone, beeper, two-way radio, smart phone, communicator, personal digital assistant (PDA), etc. The consumer uses his/her private mobile appliance to browse through various content resident or accessible through the kiosk or payment device.
