public interface CPUCard extends Card
CPUCard interface defines the operations for CPU cards, enabling
the transmission of APDU (Application Protocol Data Unit) commands between
the CPU card and the card reader.
CPU cards can be either smart cards (contact cards) or contactless cards.
PROTOCOL_RFCARD_TYPE_A, PROTOCOL_RFCARD_TYPE_B, PROTOCOL_T_0, PROTOCOL_T_1, PROTOCOL_UNKNOWN, STATUS_ABSENT, STATUS_CONNECTED, STATUS_DISCONNECTED| Modifier and Type | Method and Description |
|---|---|
ATR |
connect()
Connects to the card and retrieves the ATR (Answer To Reset) information for contact cards,
or the ATS (Answer To Select) for contactless cards.
|
void |
disconnect()
Disconnects the card from the card reader.
|
byte[] |
transmit(byte[] apdu)
Transmits an APDU command to the card reader and receives a response.
|
byte[] |
transmit(byte[] apdu,
int operation)
Transmits a Level 3 command to a contactless (RF) card and retrieves the response.

apdu
must adhere to the APDU format defined by ISO 7816-4 and EMV specifications.
In the case of ISO 7816-4 Case 4 APDUs used with T=0 CPU cards, the method automatically converts them into an appropriate sequence of TPDUs, consistent with the current operating mode (EMV or ISO). All response data from the transmitted APDU command is fully retrieved, stored, and made accessible through the returned response buffer.
