Bar code reader connection

The bar code reader connects to the touch cash register via a standard USB port. After connecting the reader to the 14" touch cash register no special setup is required. The Android operating system just shows the dialog for choosing the keyboard layout after the reader is connected. That is because the system detects the reader as a standard keyboard. You can disable this dialog with a one-time keyboard layout setting.

From the layout list select English (United Kingdom). Since the reader acts as a normal keyboard, you have to set the English layout. If the Czech layout is set, Czech characters with diacritics will be inserted after scanning the bar code. Therefore, any search for products will not work. The Android system will remember the chosen layout and the next time you connect the reader the notification about keyboard layout will no longer be displayed.
