To the fore compatibility, and cross border and cross scheme interoperability is slowly difficult to maintain against the related of rapid chip technology development. EEPROM may give way to earlier and longer lived Flash recall. Voltages for functioning smart cards are tumbling almost once a year. Security technology demand ever faster treat power.
