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.

In the simplest case the izo may be just a file manager for organising the storage and retrieval of data. The fabrication of a contactless card is somewhat different since it always involves a laminated card as shown in figure 5.

In order to avoid further delay in publishing the standard, two options were allowed to include both the front and back of the card. The communications signal may be transmitted in a similar way uso can use capacitive coupling or even an optical connection. In flip chip processing the dice is placed face down on the substrate and bonding is effected by solder reflow.

The ICs and their interconnections as well as the aerial circuits are prepared on a flexible polyimide substrate. Got Something To Say: These commands cover the ixo life cycle of the card and therefore some commands may be used before the card has been issued to the cardholder or after the card has expired. It is clear however that we should attempt to minimise the contents of the chip on both cost and reliability grounds commensurate with the particular application.

The following provides the primary interests of this standard:. Conformance to ISO standards is also likely to be a requirement and in this area ISO – 3 Electronic signals and transmission protocols is the principle standard to be considered. Created inupdated inupdated in Cards with contacts — Electrical interface and transmission protocols”.

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. It should be noted however that in the future we are likely to see a move towards 3 volts taking advantage of advanced semiconductor technology and allowing much lower current levels to be consumed by the integrated circuit. Temperature stability is clearly jso for some applications and ETSI is particulary concerned here, such that its higher temperature requirement will need the use of polycarbonate materials.

These specifications are defined by ISO as part three of the standard. The IC should still be operational at the end of the test.

This article is continued on page 3. The EPROM has been widely used in the past but the name for this application is something of a misnomer. This is an additional characteristic to the magnetic field sensor which operates off the magnetic stripe and is used to open a mechanical gate on devices such as ATMs where some vandal proofing 78116-1 are required.

Annexes are provided that give examples of operations related to digital signatures, certificates and the import and export of asymmetric keys. Introduction To Smart Cards. It specifies the standard method to maintain and query the database, it also provides format definitions. This application contains information on cryptographic functionality.

The ISO standard specifies the physical characteristics of the card. An annex is provided that shows how to control the loading of data secure download into the card, by means of verifying the access rights of the loading entity and protection of the transmitted data with secure messaging.

More particularly the slot for a card may include an extra indentation for the embossed area of the card.

Electronic signals and transmission protocols. The ISO standard is designed to address electrical signals and reset signals for synchronous cards.

The resistance of the card to static electricity is defined by a test set up as shown in figure 8.

ISO Introduction

These standards are more stringent than that described by the ISO standards. This part specifies the requirements for embossed characters on identification cards for the transfer of ios by imprinters or by visual or machine reading.

This article is continued on page 2. The IC module in a Smart Card is like any other electronic component and is not normally expected to be hit with a hammer at regular intervals. Whilst the memory is erasable by means of ultra violet light, the necessary quartz window is never available in the ICC and the memory is really used in one time programmable mode OTP.

It defines the basic commands for reading, writing and updating of card data. Ieo have been problems in the past with terminals supplying the wrong programming voltage with somewhat drastic effects. In other words when the power is removed they still retain their contents. 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 transmission characteristics operated by most 781-61 IC cards are based on an asynchronous half duplex mode of operation.

ISO/IEC 7816

It has to be said that this part of the standard could be improved and there is currently some work taking place in ISO on this very subject. The activation sequence for the interface device is defined as follows.

This part of the standard has taken a lot of effort in order to reach agreement. This is in itself an integral and complex process that we shall describe later in more detail.
