If you are not founding for Emv Apdu Commands List, simply look out our information below. The communication between a smart card and the 'outer world' is acheived by means of simple commands called APDU (Application Protocol Data Unit). APDU command CLA : ISO 7816 = 0x00: static byte: INS_EXTERNAL_AUTHENTICATE APDU command INS : EXTERNAL AUTHENTICATE = 0x82: static byte: INS_SELECT APDU command INS : SELECT = 0xA4: static byte: OFFSET_CDATA APDU command data offset : CDATA = 5: static byte: OFFSET_CLA APDU header offset : CLA = 0: static byte: OFFSET_EXT_CDATA In case 1, the body of the command APDU is empty. The APDU reader/writer module provides functions to encode a C-APDU according to its descriptor and to decode a raw R-APDU data into the appropriate descriptor. 1 of the ETSI TS 102 221 technical specification. ISO/IEC 14443-3 and ISO/IEC 14443-4 is handled by the smartphone’s hardware and/or the operating system. You can get it like this : std::vector responseBytes = apdu. In this case it confirms the selection of the “NFC NDEF tag app”. No data is transferred to or from the card, so the APDU includes only the header component. Depending on your Card Brand, different commands need to be used. Hi msramos, the exact APDU byte sequence depends from the used reader driver. Make SET NDEF more tolerant on the input format by automatically appending missing length. ) The next command you send is an invalid SELECT (by EF) command: 00 A4 02 0C 01 01 00 For that command, Lc should be 2 and the EF identifier should consist of two bytes if following ISO 7816-4. That application-level protocol is half-duplex: the NFC reader sends you a command APDU, and it waits for you to send a response APDU in return.We have a completed command to test it with Android Pay NFC: apdu = SELECT + + DF_PPSE + response, sw1, sw2 = send_apdu( apdu ) > 00 A4 04 00 0E 32 50 41 59 2E 53 59 53 2E 44 44 46 30 31 00 The dependency relationship is shown more clearly for the GET DATA APDU through Figure 3. Apdu select command 11: #define ME_CMD_SELECT.
