Solution to display name on black screen from database

I need solution for one event, where client would like to scan barcode on card and then display name for about 5 sec. in white color on total black screen. Soo I need solution where we should import database with Barcodes and names and on another side some administrator manager to manage font name and size, duration of displaying name,... Final result must be that when we scan card from Mr. Mark Sample on screen must be black background and with white text written Welcome Mr. Mark Sample for about 5 second or till next person will come.
