I ) The 1st generation Telecards:
============================

1.1 - Introduction:
~~~~~~~~~~~~

Since the middle of 80's have appeared a new generation of cards ( the
smart-cards or chip cards ) that have replaced most of the magnetics cards
applications notably for telecom payement and also for credit cards. These
cards are far more secure than the magnetics cards, and there are several kind
of cards following the application. The simplier ones are the Simple Memory
cards like the one used as Telecard for the telecom payement in the public
phone-booths ( Generaly all the memory content is readable, and there is a
maker-area that is unwritable ) , then there are more sofisticated cards:
Memeory Cards with some area read protected by a key, these cards can contain
some private informations in the read-protected area. At the end there are
microprocessor-cards (cards working following the ISO-7816 protocol), that are
the safiest ones since these cards have their own internal Operating System
that prevent I/O if the PIN (Personal Idenfication Number) has not been ent-
-ered in the cards before ( These cards are used when confidentiality is
needed, like in credit cards (bank), crypted TV access cards, health cards,
SIM cards for GSM, etc ... ).
