While there are some RS232 powered readers, they cannot be ISO 7816
compliant for Vcc supply to the card (cannot supply enough current). But if
you purchase both the readers and the cards from the same supplier, he may
be able to guarantee performance of his cards with his readers (which means
that his cards take less power current than the maximum limit in the ISO
spec). However, be sure to test card and reader with the type of PC that you
are going to use, because different types of driver ICs in the PC have
different source impedances.
