          I have done in this way.

          I Have installed Arduino IDE on RPI and to run on Arduino the program to send via serial communication ten information of the RFID it’s reading
          This in the programo uploaded on Arduino
          I use two RFID tags (TAG1 and TAG2)

                this program sends via serial communication the value “S” if i use TAG1 and “G” if I usa TAG2
                Then you have to use, on magic mirror, the module MMM-Serial-Notifications to read the value:

                {
                    module: 'MMM-Serial-Notifications',
                    config: {
                      devices: {
                        '/dev/ttyACM0': {
                          messages: {
                            'S': [
                              {
                		notification: 'CURRENT_PROFILE', 										
                		payload:  'S',
                              },
                            ],
                          'A': [
                              {
                		notification: 'CURRENT_PROFILE', 										
                		payload:  'G',
                              }
                
                            ]
                          }
                        }
                      }
                    }
                  },
                
                

                and the module MMM-ProfileSwitcher to manage all other modules:

                {
                        		module: 'MMM-ProfileSwitcher',
                			classes: 'default',
                			header: "Profile",
                        		config: {
                		
                				enterMessages: {
                					"G": "Ciao, G",
                					"S": "Ciao, S" 
                				},
                				leaveMessages: {
                					"G": "Ciao G, ci vediamo alla prossima", 
                					"S": "Ciao S, ci vediamo alla prossima",
                				},
                
                				timers: {
                    				"S": {
                        			time: 10 * 1000
                    				},
                    				"G": {
                        			time: 10 * 1000
                    				}
                			}
                
                		
                		
                  		      }
                    		},

                  @s-monti-74 So do you use an Arduino Uno or not??
                  Why do you download the Arduino IDE on the Rpi?? Is it just for programming the UNO (i use the IDE on my Windows machine) or to read the serial commands??
                  How do you connect the RFID board RC522 to the Rpi or to the UNO?? … the board has 7 used pins and 1 unused, assuming we are talking about the RFID-RC522 board

                    @s-monti-74 Stefano One more question if you use the Arduino Uno how do you connected it to the Rpi??

                      I have bought this on Amazon:
                      AZDelivery ⭐⭐⭐⭐⭐ Kit RFID RC522 13,56MHz con Reader, Chip e Scheda per Arduino e Raspberry Pi con eBook Gratuito!
                      7€

                      I have connected Arduino with PI via USb cable
                      with this connection I upload sketch to Aruino (this is why I use Arduino IDE on PI) and with the same connection datas (RFID tags) are tranfered from Arduino to PI (and the module of magic Mirror does the rest of the job)

                        Is the Arduino code you copied on the above post the complete one?? It makes no sense to me …also what wiring scheme are you using for the RFID board to the Uno??

                        Always thank you for the response

                        Another thing can you please check for errors the MMM-Serial-Notifications module entry code on the config… that you posted on the above post… it mentions an S and A instead of G and no TAG1 or TAG2

                        As always
                        Thank you again
