MFRC522 door opener

Hello
Sorry, but I don’t know very good speak English. Can you help me with this program?

This program read card ID and open door if autentification is OK. I can add only 60 String object for correct detect ID. If add String ok_61=""; and more, arduino no detect any ID. I need detect 100 ID tag for my project. Please help me. Thank you for your respons.
