Q.1

In Contactless PCD configuration Parameters set, does which parameters have to follow up 14443-3 and 14443-4 rules ?

In a Contactless PCD (Proximity Coupling Device) configuration, there are several parameters that must follow the ISO/IEC 14443-3 and ISO/IEC 14443-4 standards. These standards define the protocol and communication parameters for contactless smart card communication.

The following parameters are specified in ISO/IEC 14443-3 and ISO/IEC 14443-4 and must be followed in a Contactless PCD configuration:

RF Field Strength: The RF field strength is the strength of the electromagnetic field generated by the PCD. This parameter is specified in ISO/IEC 14443-3 and must be set within the allowable range specified in the standard.

Data Rate: The data rate is the speed at which data is transmitted between the PCD and the contactless smart card. This parameter is specified in ISO/IEC 14443-4 and must be set within the allowable range specified in the standard.

Modulation Scheme: The modulation scheme is the way in which the PCD and the contactless smart card modulate the RF signal to transmit data. This parameter is specified in ISO/IEC 14443-3 and must be set to the appropriate modulation scheme specified in the standard.

Coding Scheme: The coding scheme is the way in which the PCD and the contactless smart card encode the data being transmitted. This parameter is specified in ISO/IEC 14443-4 and must be set to the appropriate coding scheme specified in the standard.

Bit Frame Timing: The bit frame timing is the timing of the individual bits in the data being transmitted. This parameter is specified in ISO/IEC 14443-3 and must be set to the appropriate timing specified in the standard.

Protocol Initialization: The protocol initialization is the process by which the PCD and the contactless smart card establish communication and initialize the protocol for data transmission. This process is specified in ISO/IEC 14443-4 and must be followed according to the standard.

By following these parameters and standards, a Contactless PCD configuration can ensure proper communication with a contactless smart card and avoid communication errors or failures.
