ISO part 2 smart card standard
As the title implies, this part of the standard specifies the location of embossed characters on an ID -1 card for which two areas are assigned. Technical Adviser to Smart Card News. The word occasional is defined to mean not more than four hours each time and not over times during the life of the card. Created inupdated in We might like to conjecture on which is the better position for the chip in terms of mechanical stress but perhaps we should just settle for agreement.
One of the issues surrounding the use of the IC card relates to the temperature range for operational use. The principal parameters of ISO are the dimensions of the ID -1 card which are defined to be, Area 1 is for the number identifying both the card issuer and the card holder.
This anomaly has been a source of irritation and it is now widely agreed that the IC connector should be on the front of the card. The resistance of the card to static electricity is defined by a test set up as shown in figure 8. 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.
Early applications of Smart Cards emanated in France where the Transac magnetic stripes were more central on the card than that eventually defined by ISO Most microprocessor ICs operate is the active low reset mode where the IC transfers control to isoo entry address for the program when the reset signal returns to the high voltage level.
This page was last edited on 19 Aprilat The ISO standard defines three reset modes, internal reset, active low reset and synchronous high active reset. Organization, security and commands for interchange”.
Security operation commands are standardized by this criterion.
The ISO family includes eleven parts which are in a constant state of flux as they are subject to revision and update. Further problems arose in deciding on which face of the card the connector should be located.
The 7816 Standard
78166-2 with contacts — USB electrical interface and operating procedures”. This part specifies characteristics for a magnetic stripe, the encoding technique and coded character sets which are intended for machine reading.
The embossing is defined to be on the front of the card and therefore on the same side as the IC connector. The electronic 7816-22 and transmission characteristics of the IC card are fundamental to interoperability.
There is a further problem with the asynchronous character transmission that makes life difficult for a PC to act as the interface device.
uso The standard requires the card to withstand 1, torsions without chip failure or visible cracking of the card. Cards with contacts — Dimensions and location of the contacts”. Views Read Edit View history. The former frequency is the more widely used being based on the NTSC colour sub carrier frequency and results in a clock divider of in order to produce a bit per second not exact but within tolerance serial communication speed.
In practice this cannot be instantaneous and the expression “line turnaround time” is commonly encountered in the modem world. Clearly the transmitter cannot be outputting stop bits but must let the 7816–2 go high during the guard time in order to sense the line state. 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.
The IC deactivation sequence for the interface device is as follows: This means that the line must change direction depending on whether the IC is transmitting or receiving. Retrieved from ” https: The test voltage is defined to be 1.
Unfortunately the French chip position overlaps the ISO magnetic stripe definition.
The principal subjects to be considered are as follows: The ISO standard includes specifications for the commands for card management. ANSI can be contacted to get the latest version of the standards.
