Virtual business cards make networking much more seamless by integrating with the built-in contacts on digital devices. They are also much easier to create and share. And are less wasteful than traditional business cards.

In the context of smart cards, an application protocol data unit (APDU) is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange.

In the context of smart cards, an application protocol data unit (APDU) is the communication unit between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4 Organization, security and commands for interchange. [1]The structure of each command shall be according to the generalized structure defined below; each element other than the Data field is a single octet (see ETSI TS 102 221 [2]). The format of the commands is the same as the one defined in ETSI TS 102 221 [2] for T = 0 TPDU commands.
In the context of smart cards, an Application Protocol Data Unit (APDU) is the unit of communication between a smart card reader and a smart card. The structure of the APDU is defined by ISO/IEC 7816-4, which specifies organization, security, and commands for . An application protocol data unit (APDU) contains either a command message or a response message, sent from the interface device to the card or conversely. In a command-response pair, the command message and the response message may contain data, thus inducing four cases which are summarised by table 4 . Application Protocol Data Unit (APDU) is a standardized data format and communication protocol used in the interaction between smart cards - in our case, NFC tags - and card readers or host systems. APDUs define how data and commands are exchanged between these devices, enabling transactions and data retrieval in a secure and structured manner. The APDU consists of a header and a body, and the structure of the APDU is defined by the ISO 7816 standard. The APDU header contains two parts: the command code and the instruction code. The command code specifies the type of command that is being sent, while the instruction code specifies the specific operation that is being requested.
APDUs. The messages used to support the ISO 7816-4–defined application protocol (s) comprise two structures: one used by the reader side of the channel to send commands to the card and the other used by the card to send responses back to the reader.

It is not free to download, but you can find the most important parts here: http://www.cardwerk.com/smartcards/smartcard_standard_ISO7816-4_5_basic_organizations.aspx The structure of a Command APDU (C-APDU) includes a required header (CLA INS P1 P2) and an optional body ([Lc field] [Data field] [Le field]). The CLA byte defines an application-specific class of instructions, and the INS byte .
