Has anyone written a magnetic stripe card writing program with Delphi? If so please give a piece of code. Such as writing the card, the relevant code when reading the card, thank you very much!

This general DLL file is sent with the disk when you buy and write a card machine. You only need to call this DLL.

Most are COM (USB2COM) / RS232 port
Just follow the specifications ~
What about some direct PS2 analog keyboards?

What card writer do you use? I have done LK602

The description in the document is already very clear

The dll file is declared in the implementation below in the program
  function Rcard(rdata:pchar;track:integer):integer;stdcall;external'JINCARD7.dll';
  function Wcard(wdata:pchar;track:integer):integer;stdcall;external'JINCARD7.dll';

  //Main program:

  if 1 = Init_com('1,9600,n,8,1') then //Initialize the port successfully
  begin
    if 1 = Rcard(rdata,5) then //Call the read function in the library, read two or three tracks, if successful
    begin
      i:=pos ('a',rdata);
      strlcopy(str2,rdata,i-1); //Copy the content of track two in str2
      strcopy(str3,rdata+i); //Copy the contents of track three in str3
      ShowMessage('Successfully read card!'); //Display the successful card reading dialog
    end;
    wdata:= '2222222222a333333333';
    if 1 = Wcard(wdata,5) then //Call the write function in the library to write two or three tracks, if successful
    begin
      ShowMessage('Successfully write card!'); //Display the successful card writing dialog box
    end;
  end; //Determine the status of card writing based on the value returned by Wcard function

Thank youorange4923, but it crashed after writing. I don’t know why. Then only write the second track (the track content is in edit1). How to write it? I’m a beginner and don’t understand. Thank you for your help.

Now most manufacturers will directly provide drivers, which are used like keyboards, without thinking about how to read them.
