    Then, open the serial monitor. If you want more information about the library and the source use the link below. Further development will be done by community. I like this post. Upon uploading, assuming the wiring is correct and there are no errors, the user should place a tag within 4 inches of the MFRC scan area the wave-like drawing on the MFRC board and look for a print out on the Arduino serial port that looks similar to the following:.

    forum? This library allows you to read/write data from RFID tags easily. Three ways of reading/writing are available: (1) as binary data chunks of any fixed/known size.Radio Frequency Identification, or RFID, is a widely used technology developed for storing and retrieving information in radio frequency-enabled devices.

    In this tutorial we will be using the MFRC Mhz IC by MIFARE, Most Arduino boards include a V supply pin which can be used to power the RFID.I have triple checked wiring every time of course.

    If the firmware version is reported permanent, it is very likely that the hardware is a fake or has a defect.

    Then add a while loop that will work when the reading is successful.

    This is a standard classic MIFARE tag, which are used in low-security systems such as public transportation, schools and universities, and employee office access.
