RFID "Log In" System using RC522

Hey everyone, complete beginner when it comes to arduinos and I finally reached a point where Im
stumped. I need some guidance on where to look.

I'm using an RFID-RC522 with an arduino uno(intended to use a flora, but...) and the main idea
is to have rfid tags that activate certain conditionals. I've got the RC522 running and I can read my PICCs using some sample code for other RC522 projects.

Where I'm stuck is how to use the PICC IDs to meet certain conditionals as in, if [PICC ID]---> Turn On LEDs. I examined the code for other projects and they use only multiple IDs to do one thing. I want each ID to have a specific action.

I'm terrible with explanations so if im unclear please let me know where I can clarify. Thanks for the help in advance!

It is just like you say:-

if(readRFID == action1Number){
// do action 1 like :-
digitalWrite(pin,HIGH); // turn on an LED
}
