This NTT international demo card is a general type demo, produced for use in various countries probably, but known to have been demonstrated in Australia. Probably dates from around 1991-92
Early in the 1990’s Telecom Australia began to investigate the emerging smart card developments with a view to future product development. Chip cards from NTT, Anritsu, Schlumberger, and Gemplus were demonstrated. Gemplus cards were later used for internal trials “FINE”, and “INPU”
It was not until 1997 that Telecom began to roll out upgraded telephones with chip cards nationally.
