Displaying the On-Screen Keyboard

Retailers can enable the POS application to display an alphanumeric keyboard on different screens. The on-screen keyboard is useful in many cases; for example, when specifying alphanumeric product codes or when using authorizable coupons with alphanumeric codes.

The alphanumeric keyboard on the POS application can be enabled by configuring an EOM parameter or by updating the configuration files.

Note

If the settings configured in these two methods conflict with each other, the value set in the EOM parameter takes precedence.

The following image displays a sample Sale Main Menu screen with the alphanumeric keyboard enabled.

Using the EOM parameter

Enable the EOM parameter to display the on-screen keyboard on different screens to enter alphanumeric product codes. Refer to the following option:

Using the configuration files

Update the configuration files to display the on-screen keyboard on the Sale Main Menu screen to enter authorizable coupons (trigger codes) with alphanumeric codes.

Note

This method requires the Maximum Authorizable Coupons parameter to be enabled.

This task uses the following files.

FilenameLocation (POS terminal)
Control.Config.xml%PROGRAMFILES%\NCR\AdvancedStore\POS\HtmlPsxClient\config
SaleTransactionComp.SaleMainMenuView.xml%PROGRAMFILES%\NCR\AdvancedStore\POS\HtmlPsxClient\config\UIContextConfig

To enable the alphanumeric keyboard using the configuration files, follow these steps:

  1. Open the Control.Config.xml file using a text editor.
  2. Locate the InputKeypad control tag, and then add the following line inside the <Properties> section.

    <Property name="EnableKeyboardControl" value="false"/>

  3. Save the file.
  4. Open the SaleTransactionComp.SaleMainMenuView.xml file using a text editor.
  5. Locate the InputKeypad control tag, and then add the following line inside the <Properties> section.

    <Property name="EnableKeyboardControl" value="true"/>

  6. Save the file.
