Abstract
A signature card is used with a computing system. The card plugs into a host computer and is, for example, a personal computer memory card internal association (PCMCIA) card. The card includes a write-on pad for receiving input from a stylus. A memory stores the input received by the write-on pad. An interface transfers the input stored by the memory to the host computer. The card also includes an independent power source which is independent from the host computer.
