Abstract: A dispenser for the controlled one at a time dispensing of a magnetic card to an operator who inserts the card into a magnetic card reader for entry of an active number in an "Electronic Point of Sale" advertising medium reaching a predetermined captive audience while engaged in the spending of money, such as in supermarkets, shopping centers, hotels, trade shows, airports, drug stores and the like. The card is also used to imprint the card number embossed thereon on coupons in a coupon book then handed to the shopper with the card then returned to the dispenser to enable the sequential dispersing of another card. A card being reinserted into the card dispensing carousel is inserted into a card return slot to rest at one end on a retainer upper ledge until an operator depresses an actuator button forcing the end edge of the returned card past the upper edge of the retainer down onto a lower ledge of the retainer activating a carousel upper drive switch in the process.

Abstract: A double keyboarded entry terminal for use in entering money transactions between customer and vendor in conjunction with a central computer, banks, and credit card companies, with physical and/or electronic security features which preclude access to secret coded entries by customer and vendor, one from the other, and collectively, from third party "visual eavesdroppers." Security features include physical screening as well as mechanical and electronic realignment of numeric key entry functions.
