The cash register we use seems to do what you ask. It's a Sharp Electronic ER2385S. The keys are programmed with each admission price charged - children, adult, or child member, adult member, etc., and other keys are for entering program fees, or memberships. The right keys punched automatically displays the amount due, and it prints receipts. At the end of each day, it tallies the totals, and also can total each month and each year. It's simple to use. If you were looking for something more sophisticated, we have a plan for a computerized system, still unfunded, developed for us by students athe the business school at UVA. With this system, called MAESTRO, we'll have all the member information available at the desk, and we'll be able to know things like "on rainy Thursdays, 60% of our visitors are members with children under 3" and other fascinating trivia. Supposedly. If you want more information, get in touch. Carol Ely Virginia Discovery Museum (a children's museum) [log in to unmask]
