Smart cards and user terminals including the same

摘要

A smart card includes: a host integrated circuit (IC) and one or more secure authentication ICs disposed on a board. The host IC contacts a user's terminal. The host IC is configured to receive signals and execute services in accordance with the received signals. The one or more secure authentication ICs are also configured to receive signals from the host IC and accommodate an application independent of or relevant to the host IC to execute a function of the application. Accordingly, independence and security of the secure authentication ICs is improved.
