CAENRFIDTag[] MyTags = MySource.InventoryTag();

DataToWrite = Enc.GetBytes("Hello!");
MySource.WriteTagData_EPC_C1G2(MyTags[i], 3, 0, 6, DataToWrite);
Console.WriteLine("Tag written!");
byte[] DataToRead;
DataToRead = MySource.ReadTagData_EPC_C1G2(MyTags[i], 3, 0, 6);
Console.WriteLine("Tag read, value = " + Enc.GetString(DataToRead));
}
}
Console.WriteLine("Press a key to end the program.");
Console.ReadKey();
MyReader.Disconnect();
}
}
}
The read or write command will be executed on the first tag that replies to the reader chosen from those matching the
filtering criterion.
ReadTag_EPC_C1G2 and WriteTag_EPC_C1G2 methods are members of the CAENRFIDLogicalSource class.
