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.

These cards are in fact 128 bit memory in NMOS technology, and the map of
these cards are the following:
64

- use a single 5V power supply.
- low power consuption.
- NMOS technology.

Reset:
------
The address counter is reset to 0 when the clock line CLK is raised while
the control line R is high. Note th

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.

performing the WRITECARRY sequence on the stage of

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.

2.5.3 - Memory Map for new 512 bit Greek telecards
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
For a little time have appeared new Greek telecards built by Gemplus,
these cards are 512 bit memory. And it is not clearly explained how the unit
area works (Informations are welcome).

The Issuer area:
----------------
This issuer consists of 40 bits. The contents of the issuer area are
specified by the card issuer, and are fixed during the manufacturing process.
The contents of the issuer area will include data such
area may only be read.

4th S.N. 8th S.N. 6th S.N.
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.

--------------------------------------------------------------
Value = 3*8^4 + 6*8^3 + 7*8^2 + 1*8^1 + 2*8^0

TOTAL = 15818 Units

00000111 - 00111111 - 00111111 - 11111111 - 00000000 + W
11111 - 00111111 - 01111111 - 11111111 + WRITECARRY(b89)
00000111 - 00111111 - 00111111 - 01111111 - 01111111 + WRITE(b97)

00000111 - 00111111 - 00111111 - 01111111 - 00011111 + WRITE(b99)
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.

III) Schematics of Readers:
=======================
3.1 - Reader 1:
~~~~~~~~~
The following schematics is a very simple one, which will enable you to
read all kind of telecards with a chip, and also other memory cards.

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 ...).
