ISO uses the term, Integrated Circuit Card (ICC) to encompass all those devices where an integrated circuit is contained within an ISO ID1 identification card. Identification cards — Integrated circuit(s) cards with contacts — Part 1: Physical characteristics. ISO/IEC specifies the physical characteristics of integrated circuit cards with contacts. It applies to identification cards of the ID-1 card type, which.

Technical Adviser to Smart Card News.
To alleviate these problems thermo sonic bonding is often used which is a combination of the two processes but which operate at lower temperatures. In some ways this is still a relatively immature part of the Smart Card standards since the early applications used the Smart Card largely as a data store with some simple security features such as PIN checking.
The security logic can be used to control access to the memory for authorised use only. Cards with contacts — USB electrical interface and operating procedures”. The subject of multi-applications and particularly the implementation of security segregation is another subject for more detailed discussion in subsequent parts. The biggest hole in the current standards work is the lack of agreement in the security domain which one might argue is fundamental to the application platform.
This device often consists of a movable carriage that positions the card under the connector head while applying the necessary wiping and pressure action.
This is the signal line by which the chip receives commands and interchanges data with the outside world. The power supply to the IC is defined to be between 4. The standard requires the card to withstand 1, torsions without chip failure or visible cracking of the card. The following provides the primary interests of this standard:. The ISO standard defines three reset modes, internal reset, active low reset and synchronous high active reset.
ISO Identification cards – recording techniques The finished substrate is hermetically sealed with an inert material such as epoxy resin. At this stage the security keys will probably be loaded into the PROM memory but as mentioned previously we will explore this in more detail later. It is largely concerned with the management of data files but it may optionally involve additional features such as cryptographic algorithms e.
The Contact Card is the most commonly seen ICC to date largely because of its use in France and now other parts of Europe as a telephone prepayment card. While this is certainly one way of comparing cards fabricated by different companies, whether it bears any relationship to the use of IC cards in the field seems debatable.
The following list defines the main parameters that should be defined. In other words when the power is removed they still retain their contents. In general however the operating power is supplied to the contactless card electronics by an inductive loop using low frequency electronic magnetic radiation.
Because in general only 5 or 6 wires are bonded for Smart Card applications this approach is acceptable.
Define your site main menu. This will involve the setting of flags in the PROM memory that will inhibit any further changes to be made to the PROM memory except under direct control of the application.
Introduction To Smart Cards – Page 2. The reset signal is asserted by the interface device and is used to start up the program contained in the IC ROM. The RSC interface however defines two separate wires for data transmission and reception which would need hardware modification in order to interface with the single wire IC card directly.
The transmission of a single character defined as 8 bits requires 78116-1 overhead of several bits as follows: The whole operation starts with the application requirements specification.
This applies as much to telephone cards as applications using ICCs for cryptographic key carriers. This standard in its many parts is probably the most important specification for the lower layers of the IC card.
The electronic properties and transmission characteristics of the IC card are fundamental to interoperability. ISO Identification cards – Physical characteristics We have previously discussed the position and definition of the IC connector and have identified eight contacts of which six are currently defined. This part specifies characteristics for a magnetic stripe, the encoding technique and coded character sets which are intended for machine reading.
Commands and mechanisms for security operations”. The ROM type of memory is fixed and can not be changed once manufactured by the semiconductor company. The ISO standard does however allow the position of the contacts to be either side of the card.
In particular the standard defines more precisely the physical dimensions of the card as follows: For this purpose the back is defined to be the side with the magnetic stripe. This standard defines the requirements for cards to be used in financial transactions.
When the error condition is sensed then the kso should retransmit the erroneously received character. The activation sequence for the interface device is defined as follows.
This allows a far more flexible approach since the application can be loaded into the chip after manufacture. Organization, security and commands for interchange”. It also defines the purpose, location and electrical characteristics of the metallic contacts of the card.
More particularly the slot for a card may include an extra indentation for the embossed area of the card. More recently ABS has been used which allows the card to be produced by an injection moulding process.
Unfortunately the French chip position overlaps the ISO magnetic stripe definition. Mail this article Print this article.
The ICs and their interconnections as well as the aerial circuits are prepared on a flexible polyimide substrate.
