rfid
Hi all, I am new to RFID. I have connected my rfid module with KL25Z. I am trying to read my university card from the RFID. but RFID is not reading the card at all. In my main I am using the call back function by using rfid.attach(&callback), where rfid is the instance of my serial port.

Make sure your campus card is 13.56MHz Mifare based RFID. Although Mifare has dominated the HF RFID market by ISO14443-A standard, there are still many other standards.
Don't mix it up with 125KHz LF RFID or other HF standard (including ISO14443-B or Felica) or even UHF RFID.
You can verify your RFID with NFC phone, by installation some official RFID app from market.
Additionally, SM130 doesn't have an RFID antenna. How do you deal RFID access without it? Do you have antenna board?
One more thing, maybe your card or RFID module has detune issue on their antennas. You can cross check with that with NFC phone as well.
Which mbed / RFID module / RFID library? Also there are a lot of different RFID standards, are you sure that your university card is compatible with the reader you have?
