Abstract
A card is provided with a touch transmitter operable to electrically communicate touch signals to a touch-sensitive screen such as a capacitive touch sensitive screen. In doing so, for example, a card may directly communicate with a mobile telephonic device or portable computer (e.g., a tablet computer).
Claims19
A card comprising:
- a processor;
- memory;
- and
- a touch transmitter including a conductive plate, said processor operable to electrically communicate information stored in said memory to a touch sensitive screen via control signals received from said processor,
- wherein said processor is operable to change a capacitance of said conductive plate relative to a threshold, said change being at least one selected from the group consisting of below a capacitance threshold and above a capacitance threshold.
2 more elements
A card comprising:
- a processor;
- memory;
- and
- a touch transmitter, said processor operable to electrically communicate information stored in said memory to a touch sensitive screen via control signals received from said processor,
- wherein said touch transmitter includes a transistor having an isolation circuit coupled between a control terminal of said transistor and said processor.
2 more elements
A system comprising:
- a card including a touch transmitter with a conductive plate;
- and
- a device including a touch-sensitive screen,
- wherein said touch transmitter is operable to communicate information from said card to said device via said touch sensitive screen, and
- said card is operable to change a capacitance of said conductive plate relative to a threshold, said change being at least one selected from the group consisting of below a capacitance threshold and above a capacitance threshold.
2 more elements
A method comprising:
- activating a button to initiate communication;
- placing a card against a device;
- simulating a touch by said card;
- detecting said simulated touch by said device;
- and
- storing said detection within said device as data communicated by said card to said device,
- wherein simulating a touch includes increasing a capacitance of a conductive plate of said card above a capacitance threshold.
