ISO/IEC 7816

The first field H1 codes the protocol type. The answer to reset is complete 12 etu after the leading edge of the last character.

The two possible values of TS ten consecutive bits from start to bi and corresponding hexadecimal value are — Inverse convention: Interface characters Optional – T1, T2, All remaining data bytes are transferred subsequently. Rise of fall time: Should the interface device wish to effect any change to this situation then it must issue the PTS command.

Historical characters Optional – TCK The actual frequency, delivered by the interface device on CLK, is designated either by fi the initial frequency during the answer to reset, or by fs the subsequent frequency during subsequent transmission.

There are many tools out there to read an ATR. The presence of the historical characters is indicated by the number of bytes as specified in the format character defined 78166-3. Created inupdated inupdated in For the active low reset mode the IC should respond between and 40, clock cycles after the rising edge of the reset signal.


It tells the card what to do in 7186-3 5-byte header, and allow a transfer of data bytes under control of procedure bytes sent by the card. For this protocol, data can only flow in one direction for the command response pair.

For this block protocol a command may be initiated by either the IFD or the ICC albeit within the restrictions of the protocol.

F is the clock rate conversion factor and D is the bit rate adjustment factor to determine the work etu in subsequent transmissions. List of International Electrotechnical Commission standards.

When searching for a start, the sampling time 781-63 be less than 0. In the inverse convention where the logic level 1 is the space or low state the most significant bit is transmitted first. N codes directly the extra guard time, from 0 to etu.

The command message consists of a 5 character header which the interface device sends to the ICC. Identification of persons using biometric methods is outside the scope of this standard. This principle is intended to be achieved by the use of protocol type selection PTS. Each of these fields is sent in order as shown in figure The default values for F1 and D1 are 1 which is defined in the tables to give a value for F of and D of 1.

With the direct convention where the logic level 1 is the mark or high state then the least significant bit is transmitted first. High level output 7186-3 Vol: TC1 provides the value of N which defines the extra guard time to be used between successive characters.

When no TC2 appears in the answer to reset, the default value of WI is Bit b2 set to 0 is the default and indicates that no extra guardtime is required.

Other values of PI1 are reserved for future use. Cards with contacts — Physical characteristics”. Specifications of the global interface bytes ——————————————— Among the interface bytes possibly transmitted by the card in answering to reset, this subclaus defines only the global interface bytes TA1,TB1, TC1, TD1.

This maximum is named initial waiting time.

The interface characters specify physical parameters of the integrated circuit in the card and logical characteristics of the subsequent exchange protocol. High level input current Iil: In an answer to reset, the interface character TC2 codes the integer value WI over eight bits b8 to b1.
