Bit b2 set to 0 is the default and indicates that no extra guardtime is required. After these actions, the interface device waits for a new procedure. The direction of data flow is implicit on the definition of the command and hence both the interface device and the ICC need to have the necessary a-priori knowledge.

When it is required to transfer data in both directions for a particular command then a “get response” command may be used after the primary command to recover the response data. The time origin being the mean between last observation 78816-3 level Z and first observation of level A, the start shall be verified before 0. Interface character [ codes N ] TDi: It tells the card what to do in a 5-byte header, and allow a transfer of data bytes under control of procedure bytes sent by 781-63 card.

Retrieved from ” https: Created inamended in,updated in The interface device may choose to operate by using the first indicated protocol after the answer to 77816-3 and by using the default values of F and D. Table 3 — Electrical characteristics of CLK under normal operation conditions.

TC1 codes N over the eight bits b8 to b1. For this protocol, data can only flow in one direction for the command response pair. Reset of the card With a card answering synchonously, the interface device sets all the lines to state L See figure 2. Cards with contacts — USB electrical interface and operating procedures”.


ISO part 3 smart card standard

Cards with contacts — Electrical interface and transmission protocols”. Either used itself reset signal supplied from the interface device or in combination with an interal reset control circuit optional use by the card. The presence of the interface characters is indicated by a bit map technique explained below. Organization, security and commands for interchange”. When the two ends are in non-matced transmit mode, the logic state of the line may be indeterminate. This shows the two possibilities of the direct and inverse convention.

This protocol uses the parameters indicated by the answer to reset, unless modified by the protocol type selection. It codes over the least significant bits b4 to b1 the selected protocol type T as coded in TD bytes. They carry information relating to the available communication protocols as well as the programming voltage and current parameters for the EPROM.

Other values are reserved for future use by ISO When searching for a start, the sampling time shall be less than 0. In all other cases TCK shall be sent. When P3 is equal to zero the data from the card will be bytes. If internal reset is implemented, the voltage supply on Vcc is mandatory.

Created inupdated inamended in According to its abstract, 716-3 specifies the operating conditions of an integrated circuit card that provides a USB interface. According to its abstract, it specifies a card application. The dialogue between the interface device and the the 781-63 shall be conducted through the consecutive operations: There are many tools out there to read an ATR.

There are clearly other possibilities and the use of these characters is still subject to agreement.

ISO/IEC 7816

It gives the identifier, name, description, format, coding and layout of each DE and defines the means of retrieval of DEs from the card. An active 78116-3 on VPP should not only be provided and maintained when requested by the card.


The historical characters may be used to convey information relating to the life cycle of the card. The presence of the historical characters is indicated by the number of bytes as specified in the format character defined below. The following five values are defined:.

The loaded data may contain, for example, code, keys and applets. This maximum is named initial waiting time. Other values of PI2 are reserved for future use.

The binary encoded fields are compared against tables supplied in the standard to achieve actual values for F and D as defined below. The choice and conditions of use of cryptographic mechanisms may affect card exportability.

Programing voltage input optional use by the card. Each data bit is valid until the next falling edge the following clock pulse on CLK. Historical characters max,15 TCK: This results in an implicit selection of the protocol and the communication parameters. Interaction between the interface device and the ICC results in successive commands and responses. A character consists of ten consecutive bits: The answer to reset is at most 33 characters including the initial character and consists of 5 fields.

The use of 4 bits restricts the maximum size of the historical character field to 15 bytes. High level output voltage Vol: This limitation was really due to the use of a single byte for defining the length of the data related to the command.
