I am trying to connect 5 RFID readers to one arduino is this possible?
I am using an arduino mega which i believe has 4 serial ports.
I am not sure how to use all these.....
Yes because any i/o pin can be used for this,
happy halloween and have fun reading
It depends on what sort of output you have from the reader. I used three readers in this project:-

The other thing to watch is that if they are too close together they interfere with each other. You can also use the software serial library to increase the number of serial ports.
