which is like, the keyboard & card reader both connected simultaneously the keyboard inputs the card reader & card reader output at PS2 keyboard port but still missing what will

Hi, you can take a look at Syncotek SC-750, it is one TTL card reader with RS-232 interface, baud rate adjustable; USB port and TTL at optional.
Hope this helps!
