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 an
e 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 ... ).





       About tele
 the less safe ones, don't think

that  you  are  going  to  phone freely for that, in fact no.  All the data are

readable since  there are  no confidential data inside, the cards are well done

enough to be  very secure for  the payement of telecom communications in public

booth.



       So, what is a phonecard exactly ? In fact generaly it's a 256 bits EPROM

( French likde cards ),  or a 128 bits EEPROM (German like cards) with a serial

output and some other control pins.



       Then why can it not be refilled ?   Well,  indeed to refill the card you

will  have to erase the cards with UV,  knowing that the cards is coated in  UV

opaqued resin that prevent  UV from reaching the silicium chip, and even if you

could  to erase the chip  you will have to program the manufactuer area that is

write-protected by a lock-out fuse that was fused after the card programming in

factory.



       Neithertheless it can be very interesting to study how
kind of data are inside and  how the data are maped  inside or to

see  how many units are left  inside for exemple.  Besides  there  are a  great

number of  applications of  these cards when there  are used (only for personal

use of course) , since  you can use them as key to open a door, or you can also

use them as key to secure a program, etc ....



       French Telecards have been created in 1984 and at this time constructors

decided to build these cards in NMOS technology but now, they plan to change by

1994 all readers  in the public booths  and use CMOS technology. Also they plan

to use  EEPROM to secure the cards and to add many usefull infornations in, and

you will perhaps use phone cards to buy you bread or any thing else.



These cards are called Second Generation Telecards.

II ) The 2nd and 3rd generation Telecards:

     =====================================



   2.1 - Introduction:

         ~~~~~~~~~~~~



   These cards are in fact 128 bit memory in NMOS technology, and the map of

   these cards are the following:



        64
t EEPROM (5x8 bits).

        24 bits set to "1".

   2.3 - Main features:

         ~~~~~~~~~~~~~



        - ISO 7816- 1/2 compatible.

        - use a single 5V power supply.

        - low power consuption.

        - NMOS technology.



   2.4 - Time Diagrams:

         ~~~~~~~~~~~~~



Reset:

------

  The address counter is reset to 0 when the clock line CLK is raised while

the control line R is high. Note th
o 7.

   The address counter is incremented by 1 with each rising edge of the clock

signal Clk, for as long as the control line R remains low. The data held in

each addresse
h time Clk falls. It is not

impossible to decrement the address counter, therefore to address an earlier

bit, the address counter must be reset then incremented to require value.





Write:

------

   All unwritten or erased bits in the address 64-104 may be unwritten to.

When a memory cell is unwritten, it is set to 0. The addressed cell is

unwritten to by the following sequence.



1- R is raised while Clk is low, to disable address counter increment for one

clock pulse.



2- Clk is then raised for a minimum of 10ms to write to the address bit.



When to write operation ends, and Clk falls, the address counter is unlocked,

and the content of the written cell, which is now 0, is output to I/O contact

if the operation is correct.

The next Clk pulse will increment the address by one, then the write sequence

can be repeated to write the next bit.

WriteCarry:

------
 performing the WRITECARRY sequence on the stage of

the next highest weighing to that to be erased.



The writecarry sequence is as follows:



1 - Set the address counter to an unwritten bit in the next highest counter

stage to that to be erased.



2 - Increment is disabled on the following rising edge of R where Clk remains

low.



3 - Clk is then raised for a minimum of 10ms, while R is low, to write to the

next address bit.



4 - R is the raised again while Clk remains low to disable increment a second

time.



5 - Clk is the raised for a minimum of 1ms, while R is low, to write to the

addressed bit a second time, erasing the counter level immediately below that

the addressed bit.

                                  digit           digit            digit


 the digit is written in reverse binary

               (MSB right, LSB left)

NOTE 2: The Serial Number is the one printed on the back of the card.

        The last two digit are not coded in the memory [TBC].





The Counter area:

-----------------



   The counter area stores the card's units. Its initial value is specified by

the card issuer and set during manufacturing.



The counter area  is divided into a 5 stage abacus counter,  or 4 stage abacus

counter. The octal value of each stage is defined by the number of bits set to '1' and this stage value must

be weighted by the coeficient 8^n ( where n is among [4..0] or [3..0]).



    Exemple: For a 5 stage octal unit counter with 15818 units left.

        Etc ....







Note that you can only decrease the counter and it is not authorised  to write

in the counter a value greater than the old value.



NB: In fact most of the card units don not represent telecom units,  but money

units, for exmeple in german cards each telecom unit represent 30 pfennigs.

     3.2 - Reader 2:

           ~~~~~~~~~



     This Reader which is indeed a reader/writter will enable you to read/write

most of the more current memory cards (and notably telecards), and also smart

cards working under ISO7816 protocol (Credit cards, SIM cards, Health cards,

Videocrypt TV cards, etc ...).
