I'm working with RFID RC522 using Raspberrypi 3B+. I'm following https://github.com/mxgxw/MFRC522-python this package and works like a charm. I can able to read the data from the card, able to write as well.
the problem is, this package is returing the card data as Array of strings.
# Print UID print "Card read UID: %s,%s,%s,%s" % (uid, uid, uid, uid) <== Here
The value looks like : 185,113,174,85 and I'm concatinating this array into a single string and storing it in db for further functionalities.
Now, I expecting to get the same Uid from the card by using USB based RFID Reader 13.56Mhz . But Unfortunately, the value I'm getting is not same.
The value USB RFID Reader returns 1437495737
How to rectify this. I need to get the same value for both RFID RC522 and USB based RFID Reader.
