title: What options are there for reading passive RFID tags up to 1 meter with an app?
body: <p>I have heard that you can use NFC but supposedly that only works up to 4cm - I need 1 meter.</p>
  
  <p>Do I need an RFID reader board, an RFID antennae and an Arduino board to glue the reader board and the antennae together?</p>
  
  <p>What's the easiest approach?</p>
