Abstract:
1. A test device for testing a contact type, a contactless type or a contact/contactless hybrid type smart card, the device comprising: a logic tester which generates a test pattern to test a smart card, and which compares a received response pattern from the smart card with a predetermined response pattern to determine a status of the smart card; a contactless interface unit that modulates the test pattern onto a carrier signal to transmit the modulated signal to the smart card, demodulates a sub-carrier signal received fom the smart card to restore the response pattern, and provides the logic tester with the response pattern, when the logic tester operates in a contactless test mode; and a contact interface unit which transmits the test pattern received from the logic tester to the smart card over a wired connection, and which provides the logic tester with the response pattern, when the logic tester operates in a contact test mode, wherein the contactless interface unit comprises: a logic interface that receives a clock signal, a peak-to-peak voltage signal, a modulation index, and logic data from the logic tester; an antenna; a transmitting unit that generates the carrier signal using the clock signal and the peak-to-peak voltage signal, and modulates the logic data based on the modulation index to transmit the modulated logic data via the antenna; and a receiving unit that demodulates the sub-carrier signal received from the antenna, and restores the response pattern to provide the logic interface with the restored response pattern.
