interface shall limits the CRD_VCC output current to
200 mA maximum, under short circuit conditions. The
power supply must be capable of providing a 100 mA pulsed
current during the data transaction. The ISO7816−3,
paragraph 4.3.2, defines this 400 ns pulse as a function of the
According to the ISO7816−3 and EMV specifications, the
Beside the continuous current capability, the smart card
