Although only one payment device  10  is shown in  FIG. 2 , the present invention is not limited to one payment device and can include a multitude of varied payment devices that are capable of communicating using a wireless protocol. 
         [0033]    The payment terminal  28  is preferably a computer device that operates as a point of sale terminal for goods or services rendered. In one preferred embodiment, the payment terminal  28  includes a management module  28 A that processes financial transaction instructions received from the device  10  and provides an acknowledgement message to the payment device  10  upon completion of a transaction. 
         [0034]    As shown in  FIG. 2 , the payment terminal  28  is preferably in communication with a financial institution  30 , such as a bank, which has access to a conventional payment network for transaction authorizations. 
         [0035]    In one preferred embodiment, as shown in  FIG. 2 , the system includes a map server  24  that provides maps to the payment device  10  on demand. As used herein, the term ‘map’ refers to a representation of the whole or a part of a geographic area. Use of the map server  24  is discussed in connection with  FIGS. 3 and 4  of the disclosure. 
         [0036]    The network  26  is preferably a wireless network that can be an 802.11-compliant network, Bluetooth network, cellular digital packet data (CDPD) network, high speed circuit switched data (HSCSD) network, packet data cellular (PDC-P) network, general packet radio service (GPRS) network, 1x radio transmission technology (1xRTT) network, IrDA network, multichannel multipoint distribution service (MMDS) network, local multipoint distribution service (LMDS) network, worldwide interoperability for microwave access (WiMAX) network, and/or any other network that communicates using a wireless protocol. 
         [0037]    Referring now to  FIG. 3 , an example graphical user interface (GUI)  32  provided by the GPS module  18 A is shown. In one preferred embodiment, the GPS module  18 A displays the user interface  32  on the screen  20  of the payment device  10  and prompts the user to enter either an address or MAP name that identifies a particular geographic area to be displayed on the device  10 . In another preferred embodiment, the GPS module  18 A displays the graphical user interface  32  on a Personal Computer (PC) attached to the device  10  and prompts the user to enter either an address or map name to be displayed on the device  10 . 
         [0038]    As shown in the  FIG. 3  example, the graphical user interface  32  of the present invention includes a map area  34 , a map-name/address area  42  with map-name/address entry area  44 , an access-map button  46 , a charge-amount entry area  52 , and a select-payment-location button  48 . 
         [0039]    The map-name/address area  42  provides a listing of previously accessed maps and entered addresses that are user selectable and available for display on the device  10 . In the event a particular map name or address is not included in the area  42 , map-name/address entry area  44  provides a data entry area for entering the particular address or map name which, upon selection of access-map button  46 , is displayed on the device  10 . In one preferred embodiment, the GPS module  18 A requests the associated map from the map server  24  which is then displayed in map area  34 . In another preferred embodiment, the GPS module  18 A accesses the associated map from memory  18  of the device  10  and displays the same in the map area  34 . As shown in  FIG. 3 , in one preferred embodiment, the map displayed can include latitudinal  38  and longitudinal  36  coordinates representing varying degrees of specificity concerning geographic locations and coordinates. 
         [0040]    Once a map is displayed in the map area  34  and the user selects select-payment-location button  48 , the user can then select transaction locations for automatic payment. For example, in one preferred embodiment, upon selection of select-payment-location button  48 , the GPS module  18 A displays a cursor that overlays the displayed map and allows the user to identify a particular location  58  on the map where a payment is to be automatically commenced. 
         [0041]    Once a transaction location  58  is identified on the map, the GPS module  18 A activates the transaction amount data entry area  52  that allows the user to specify a monetary amount for the transaction. 
         [0042]    Once a value is entered into data entry area  52  and the user selects the save button  54 , the GPS module  18 A saves the identified transaction location and entered transaction amount to the data storage area  18 B. For example, in one preferred embodiment, the GPS module  18 A calculates transaction coordinates using one or more particular transaction locations  58  identified on the map and stores the calculated transaction coordinates along with the entered transaction amount to the data storage area  18 B. Upon the user selecting the exit button  64 , the GPS module  30  terminates display of the GUI  32 . 
         [0043]    Turning now to  FIG. 4 , a typical financial transaction executed by the system using the techniques of the present invention will now be described. As shown in the  FIG. 4  example, first, the GPS module  18 A of the payment device  10  calculates the current geographical coordinates of the device  10  upon receiving a plurality of satellite signals  60 . As mentioned previously, in one preferred embodiment, the GPS module  18 A uses a trilateration technique to determine geographic coordinates of the device  10 . Next, the GPS module  18 A compares the calculated geographic coordinates to predefined transaction locations stored in the data storage areas  18  of the device  10 . In one preferred embodiment, if the calculated coordinates are within a particular distance of one of the predefined transaction locations  64 , the GPS module  18 A activates the payment module  18 C to initiate a financial transaction  66  over the network  26 . If the calculated coordinates are not within a particular distance of any of the stored transaction locations  64 , the GPS module  18 A continues to calculate the device&#39;s current geographical location and continues its comparisons. 
         [0044]    Once the payment module  18 C is activated, the payment module  18 C initiates a network connection  68  to the payment terminal  28 . In one preferred embodiment, where the payment device  10  is a cellular phone, a telephone company (TELCO) provider can be used as a gateway into one or more payment networks. For example, an arrangement can be made between the user of the device  10  and the TELCO provider such that the TELCO provider would charge a fee for supporting location dependent transactions. 
         [0045]    In one preferred embodiment, the payment module  18 C initiates the network connection by polling for a wireless network connection as is known in the art. Preferably, the network connection is a secure connection that includes encryption and digital authentication. Upon the payment terminal  28  verifying the authenticity of the payment device  10 , the payment terminal  28  grants network access to the payment device  10 . 
         [0046]    Once the payment device  10  is connected to the network  26 , the payment module  18 C can send financial transaction instructions to the payment terminal to charge a particular account a predefined transaction amount automatically  70 . 
         [0047]    Next, upon transmission of a financial transaction instruction from the payment device  10  to the payment terminal  28 , the management module  28 A of the payment terminal  28  transmits an authorization request to the financial institution  30  for approval  72 . In one preferred embodiment, the financial institution  30  in turn forwards the authorization request through a conventional payment network to a credit grantor. Based upon the payment device user&#39;s account status and the amount of transaction, the credit grantor can authorize or deny the authorization request  74 . The grantor&#39;s response is then routed back through the financial institution  30  to the payment terminal  28  and payment device  10 . 
         [0048]    A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, payment terminals can provide messages to payment devices that could include information relating to upcoming offers and sales. Also, the steps described above may be modified in various ways or performed in a different order than described above, where appropriate. Accordingly, alternative embodiments are within the scope of the following claims.
