Hi fellas, I have a MFRC522 and 7" Inches TFT LCD with CTE TFT LCD/SD Shield for Arduino Mega.

The main problem is the MFRC522 must be connected to 50, 51, 52, and 53 but they already occupied by CTE TFT LCD/SD Shield for Arduino Mega.

Any idea/s how to do this?

RFID can share MO/MI/CLK, but must have CS-pin connected to other pin than 53.
