BACKGROUND 
       [0001]    Current kiosks and self-service systems generally use some form of flat-panel display with a touch screen overlay. Liquid crystal displays (LCDs) are the current technology of choice due to their size, cost, and other factors. This single panel provides the majority of the user interface. Additional user interface elements are sometimes provided on adjacent devices such as credit card readers and PIN pads. 
         [0002]    Display technology is advancing rapidly in the area of flexible bi-stable displays. These products are capable of high-quality images on flexible materials or substrates, and generally will “remember” the most recent image when power is removed for months or even years. 
         [0003]    It would be desirable to provide a transaction station with an enhanced user interface. 
       SUMMARY 
       [0004]    A transaction station with an enhanced user interface is provided. 
         [0005]    An example transaction station includes a housing, a plurality of peripherals in the housing, a touch screen extending substantially across the housing including a display for displaying information and a touch overlay for recording operator selections, and a processor for executing transaction software, wherein the transaction software causes the display to display the information and receives the operator selections from the touch overlay during a transaction. 
         [0006]    Example types of displays may include bistable, cholosteric, liquid crystal, and organic LED (OLED) displays.

         [0016]    Touch screen  16  may display many different types of information. For example, touch screen  16  may display active transaction instructions and options, information and instructions related to the transaction such as running balance, coupon and loyalty information (reminder to scan loyalty card), and completely unrelated information such as ads for other products and services, including products and services in the same store (e.g., pharmacy, photo lab, and deli). 
         [0017]    In some embodiments, display  20  may display messages in a plurality of colors. 
         [0018]    Transaction station  10  may include a self-service or assisted-service transaction station in various forms, such as a kiosk, a terminal, an automated teller machine, a point-of-sale checkout station, or a self-service checkout station. Consequently, transaction peripherals  18  include whatever peripherals are necessary considering the purpose of transaction station  10 . 
         [0019]    An example kiosk may include a card reader and a printer. An example automated teller machine may include a currency receptacle and dispenser, a card reader, a personal identification number (PIN) keypad, and a printer. An example point-of-sale checkout station may include a code reader, such as a barcode or radio frequency identification label tag reader, a scale, a card reader, a PIN keypad, a coin dispenser, an electronic article surveillance (EAS) tag deactivator, a cash drawer, and a printer. 
         [0020]    With reference to  FIG. 2 , an example embodiment of transaction station  10 . In this example, transaction station  10  is a self-service checkout station  32 . Self-service checkout station  32  may be one of a group of self-service transaction stations  32 . An attendant station may monitor the group of self-service transaction stations  32 . 
         [0021]    Self-service checkout station  32  includes housing sections  34 - 38  which support mounting of touch screen  16  and peripherals  18 . 
         [0022]    Self-service checkout station  32  includes a dual-aperture barcode scanner with scale  40 , a card reader  42 , a cash (currency and/or coin) dispenser/acceptor  44 , a receipt printer  46 , one or more security scales  48 , and a light post  50  with signaling light  52 . 
         [0023]    Self-service checkout station  32  may be configured with more or fewer peripherals  18 . For example, self-service checkout station  32  may include a radio frequency identification tag reader, a signature capture pad, check reader, or other peripheral as dictated by the retailer where self-service checkout station  32  is located. 
         [0024]    Touch screen  16  is mounted to housing section  38 , in a position above scanner  40 , card reader  42 , cash dispenser/acceptor  44 , and receipt printer  46 . Touch screen  16  spans substantially the entire width of housing section  38 . 
         [0025]    Touch screen  16  displays instructions and prompts in an active portion  24 . Active portion  24  includes information involved in completing a transaction. Active portion  24  may vary in size and gradually shift horizontally as the transaction progresses, so that the displayed information is positioned roughly adjacent to and above the related peripherals. 
         [0026]    In a remaining passive portion  26 , touch screen  16  displays advertisements, information about products, promotions, eye-catching graphics inviting shoppers to use the system (commonly called “attract screens),” or possibly nothing. Passive portion  26  includes information that is not necessarily involved in completing a transaction. However, passive portion  26  may display information related to products involved in a transaction. Passive portion  26  may include touch sensitive areas that a customer may select if the customer wishes further information. 
         [0027]    Card reader  42 , cash dispenser/acceptor  44 , and receipt printer  46  are also located within housing section  38 . Barcode scanner  40  is mounted within housing section  34 . Security scale  48  is mounted within section  36  under bag racks  54 . 
         [0028]    When a customer approaches self-service checkout station  32 , touch screen  16  may display an initial message, such as “Checkout faster here”, alternating with “Touch screen to begin”. Active portion  24  may be centered. One or more passive portions  26  may occupy the rest of touch screen  16 . 
         [0029]    As a customer proceeds through a transaction, transaction software  30  causes touch screen  16  to display transaction related information and prompts, and records selections necessary to complete the transaction. 
         [0030]    For example, following each step in a transaction requiring a customer to act, transaction software  30  may cause touch screen  16  to display a message, graphic, or other prompt requesting a selection from the customer or directing the customer to an appropriate peripheral  18 . 
         [0031]    Transaction software  30  may also generate voice messages supporting or echoing messages or prompts displayed by touch screen  16  through one or more speakers  56 . 
         [0032]    An example sequence of displayed messages that follows a transaction flow is illustrated in  FIGS. 3   a - j.
