I got a RFID-RC522 along with two RFID cards. I am using Arduino and trying to read cards. I have successfully read those card which was along with RFID-RC522. But when I am trying to read different card means my friend's office card then nothing is happening.
Thank for your help...

Simple Solution: increment supply voltage, like 3.3 to 3.6V.
I am also powering the reader with 4.8V and it has been working without troubles since months. I was having the same issue as you, maybe it could read other cards eventually but no more than the ones that goes with the RC522 reader.
This is because some cards needs more energy to transmit the data to the anthem of the reader. When you increment the power, you can also arrive to other cards that maybe need a little power extra to transmit information.
Cards readed succesfully: Mifare 1K, Mifare Desfire, Credit Cards. (No more card types have been tried.)

RC522 only works on 13.56MHz frequency, wich is the most common. Other frequencies can be used in RFID cards, I think this is the problem because RC522 should read other cards formats (even if not suported). If this was the case RC522 should be able to read the header of the card in wich is described the card type, but if thecard works in other frequency it shouldn't be able to read it at all.
