RC522 RFID and writing tag

Hi everybody,

I have a question. I bought an RC522 RFID module on ebay. I got also some tags. Can I write the tags IDs with this module. If yes, could you please show me the way?


You can NOT change/write the UID, unless you have a changeable mifare card http://m.ebay.de/itm/321204874385?nav=SEARCH&sbk=1

hi rena,

I have one. I could not find any source code on internet. How will I do that. If it is possible, could you please give me a website for example. Thanks

There's many links online. For indepth understanding of RFID there's a popular youtube video online and an informative website (1) also there's this link here that can give more information about how to connect RFID to arduino and make a cool project (2).
