In the early 1990s smart cards ran on 5V + or - 5%. Then it was widened to 5V + or - 10%. By 97 there were a good number of cards about that were dual voltage: 5V or 3V, both with 10% tolerance. Now there are also 1.8V cards - but they should tolerate the higher voltages. The dominant standard (ISO/IEC 7816) and specs (EMV for payment cards, GSM and other ETSI specs for mobile phone cards) have introduced methods for the terminal to work out what to do when a card is being initialised.
But smart cards as discussed in this list are NOT the same as Smart Media cards.
