CardTransceiver Class

Definition

Namespace:

Iot.Device.Card

Assembly:

Iot.Device.Bindings.dll

Package:

Iot.Device.Bindings v3.0.0

Abstract class implementing a specific Write and Read function This class allow to transceive information with the card This class has to be implemented in all RFID/NFC/Card readers So Mifare cards can be used the same way independent of any reader

Properties

MaximumReadSize	The maximum number of bytes that can be read from the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver).
MaximumWriteSize	The maximum number of bytes that can be written to the card in a single transaction, (excluding CRC). This is constrained by the operating mode as well as transceiver limitations (such as the size of a FIFO buffer in the transceiver).

Methods

ReselectTarget(Byte)	Once you have an authentication operation failing with Mifare cards or a read/write, the card stop. TYhe only way to have it back is to send the unselect and anti collision. This function provides this feature
Transceive(Byte, ReadOnlySpan<Byte>, Span<Byte>, NfcProtocol)	This function has to be implemented by all NFC/RFID/Card readers. This function is used in exchange of data with the reader and the cards.
