| 摘要 |
The present invention is directed to a security card apparatus, comprising: electronic circuitry, e.g. smart card chip, flash memory, CPU, and memory, for providing a service to a host; a common computer communication interface, for connecting the security card apparatus to the host; a substrate of about a typical business card form, on which the circuitry and the communication interface are embedded. The substrate may comprise an out-standing part on which contacts of the common computer communication interface are embedded, thereby allowing the apparatus to be connected to a corresponding connector of the host. The apparatus may further comprise a biometric sensor such as a fingerprint reader for sampling a fingerprint of a user for authenticating the user.
