multiple rfid rc522 on arduino leonardo

Hello, i intent to make a project that will be using the following pieces:

1 x Arduino Leonardo
1 x Ethernet shield
2 x rfid rc522 card readers
1 x 4 relay module
1 photocell (gate photocell presence detector)
1x display with 4 pins (vcc gnd sda scl)

Can i plug it all to an Arduino Leonardo?
Or do i need something more?

The code i have until now and the design of the project is in GitHub at GitHub - BrixSat/Parking-Gate: Arduino parking gate controller


Any help is always appreciated.

Thanks in advance for your help.

It would be far easier to do all that with a Mega.

Ok thanks for the input. Will buy one today.

The arduino mega 256 v3 as arrived today :D

I have read some thing and must give it a go. I have not seen where to use multiple rfid rc522. Thanks for the help.

It hardly seems that you need to be told to connect the first device to Serial1, the second to Serial2, and the third to Serial3. If you do need to be told, consider yourself told.
