title: AdaFruit pn532 NFC/RFID detecting multiple tags?
body: <p>I am working off an Arduino UNO with an AdaFruit pn532 NFC/RFID shield.  The Goal is to have a shoe box, with a false bottom. Under that false bottom would be my prototype, which hopes to be able to tell every mifare tag (up to 6) that is in the box, above the false bottom. </p>
  
  <p>I started with one shield, and had it detecting up to two tags with in range..  </p>
  
  <p>If i placed one tag it logged that one tag over and over again in the loop() of my sketch.</p>
  
  <p>If I placed two tags above the shield it logged the two tags in an alternating pattern.  ("tag1","tag2","tag1"....)</p>
  
  <p>But when I placed three tags, it only logs the third tag..  This is essentially using the adaFruit mifare example.</p>
  
  <p>I then set up the UNO with two shields and in the loop() checked both..  worked exactly the same.  Once there were three tags, regardless of which pn352 they were placed on (2 on one, and 1 on another, or all three on one) it only logs one tag.</p>
  
  <p>Has anyone tried to create anything that would detect up to 6 tags in range?  If so could you share your discoveries?</p>
  
  <p>New to Arduino..</p>
  
  <p>thanks</p>
