A system and method for performing integrated lottery ticket and merchandise transactions using a point-of-sale terminal that generates a single sales receipt containing all pertinent lottery ticket and merchandise transaction information. The lottery tickets generated include fractional value and "quick-pick" lottery tickets. A group of point-of-sale terminals are connected to a POS controller which communicates with a lottery data processing system. An encrypted authentication code also printed on the sales receipt allows the lottery player to verify all lottery ticket transaction information, as needed.
