Arduino RFID UID to string

In the for loop that prints the uid, I tried putting this line of code to store the uid in a string. String userid = mfrc522.uid.uidByte[i] < 0x10 ? 0 : if (mfrc522[reader].uid.uidByte, mfrc522[reader].uid.size = 30 75 7E 7A) uid.uidByte is NOT a text string; That is not how you compare two text strings. You would In order to get the HEX string you can use this code : String UID_HEX=; Serial.print(Printing HEX UID : ); for (byte i = 0; i < mfrc522.uid.size; i++) {String
