TB-100

Security smart card - this page is a stub

TB-100 was a credit card-size ISO-7812 smart card, developed around 1993 by
Philips (France). It was intended for financial transactions and electronic
wallet applications, and used as a security token — in combination with a PIN —
for cryptographically secured commu­ni­cations equipment produced by Philips
Usfa/Crypto, such as the PNVX secure telephone and the PFDX fax encryptor.


There are two types of TB-100 cards: one with the contact pads in the top left
corner (the old type) and one with the contact pads at the left centre (the new
type). The lat­ter was introduced in 1990 and became the standard format. The
physical specifications are defined in ISO 7816.

Early card readers, like the PE-118 and PE-112 were capable of reading both card
types — they had two sets of contacts — but later ones like PE-122 were only
suitable for the newer model. The electrical specifications and the layout of
the contact pads are identical for both card types.   



The actual smart chip is located under the gold-plated contact pads. It's a
monolythic (single-chip) design in HCMOS technology, and comprises a Motorola
68H05 8-bit microcontroller, 128 bytes RAM, 6KB ROM and 3KB EEPROM. The bare
chip is bonded directly to the contact pads, and is then embedded in a plastic
ID-1 format card that measures 85.6 × 53.98 × 0.80 mm.

Card readers

In order to prepare TB-100 cards for use with Philips crypto-equipment, and to
store suitable key material on them, Philips released a series of smart card
reader/writers. Initially such readers had to be built into a Personal Computer
(PC) and required a proprietary interface in the form of an ISA bus card, but
later units were simply connected to the COM port (i.e. the RS232 serial port).


PE-118   1988

PE-118 is an early smart card reader that could be placed in an empty 5¼" bay of
a Personal Computer (PC) of the era. It was introduced around 1988 and requires
a large ISA bus expansion card to be installed as well. The reader has a
parallel interface and is connected to the expansion card by means of a flat
cable.

PE-122   1994

PE-122 was an external card reader that could be connected to the RS232 serial
port (the COM port) of any regular PC of the era. It was intro­duced around 1990
and is suitable for most existing smart cards, including the TB-100.

Answer To Reset   ATR

When a smart card is powered on, or when reset is asserted, it produces a
so-called Answer-To-Reset (ATR) — a string of hexadecimal values (bytes) that
allows the card reader to check for compatibility. The ATR has a variable length
that should be parsed by the reader on-the-fly [9].

The TB-100 card produces the following ATR:
3F 67 25 04 21 20 00 07 68 90 00
