  • Publication number: 20020174013
    Abstract: A method and system for providing advertisement information on chip cards, and for the distribution of the resulting revenues. It also includes tracking and storing of integrated relational information regarding advertisement information, products, and customer's buying habits with respect to those products. At the time a customer uses a chip card to purchase an item, particular advertisement information is stored onto the card based on information characterizing the customer (user). The chip card may or may not incorporate an electronic display for showing the advertisement directly on the card. Credit transactional fees are adjusted based on advertising download rates and other parameters.

  • Patent number: 6450407
    Abstract: A method and system for providing advertisement information, including advertising as well as sales promotions, on chip cards that additionally involves an electronic money rebate to the consumer, and for the distribution, accounting, and recovery of the associated electronic money rebates. Rebates are conveyed to the consumer by communication from the advertisement information provider to a customer's chip card via a multiplicity of possible channels including: a personal computer, a portable chip card reader, a point-of-sale (POS) terminal, a handheld device, a home or business telephone, a vending machine, a cellular phone, a pager, a mass transporation payment station, a television and/or television set-top box, or an automated teller machine (ATM). Rather than giving a discount at the point of sale, a rebate in the form of electronic money is stored in chip card memory.

  • Patent number: 6402039
    Abstract: A chip card including a flexible body; at least one semiconductor chip supported within the flexible body and comprising a memory for storing the information; a display element capable of displaying at least a portion of the information stored in the semiconductor chip, the display element being supported within the flexible body and comprising display areas viewable from at least one side of the chip card; circuitry for controlling the display element; the chip card being capable of undergoing flexing of the type and magnitude experienced by a card during normal use, handling, and storage (e.g., storage in a pocket, wallet, or purse) without permanent damage to the display element and without permanent loss of the displayed information. A chip card may include a power source to provide multi-media capabilities by driving a speaker/microphone or showing a series of images to produce an animated display or film clip.

  • Patent number: 4985143
    Abstract: Column chromatography beds are packed through the application of static force. A slurry of the chromatography bed material and a non-viscous liquid is filled into the column plugged at one end, and allowed to settle. The column is transferred to a centrifuge, and centrifuged for a brief period of time to achieve a predetermined packing level, at a range generally of 100-5,000 gravities. Thereafter, the plug is removed, other fixtures may be secured, and the liquid is allowed to flow out through the bed. This results in an evenly packed bed, with no channeling or preferential flow characteristics.
