Abstract
A contactless smartcard type integrated circuit needing only two pins for performing a standard ATPG test is disclosed. A scan test may be performed using one pin for the clock and the other pin for the input and input of the scan test data. Additionally, security is enhanced by using an embedded signature generator to avoid observation of the data shifted out.
