title: RFID tags writing
body: <p>I'm planning to create a stock manager based on RFID. At this moment I'm Newby using this technology. I was looking around for info about how to write custom data on a tag (for instance, name of the product, production date and so) but can't find anything. </p>
  
  <p>I would like to know how to store the info (maybe an array I guess) and how to read/write it. </p>
  
  <p>Hope you people can suggest me a good book or tutorial. </p>
  
  <p>Many thanks, cheers. </p>
