A Houston school district has installed a Web-connected, computerized cash register system that enables parents to monitor and restrict what kids can buy in the cafeteria. They can visit a special web site, and click on menu items their kids won't be allowed to buy. It also allows parents to set up pre-paid accounts, so the kids don't have to bring lunch money. The system is called Primero Food Service Solutions and is made by Cybersoft Technologies, also in Houston.
