title: Python, ACR122U NFC reader can it read the ID of the Android phone is that possible?
body: <p>I have a ACS ACR122U NFC Reader / Writer when i hover over the reader with my Samsung s7. The led becomes green so the reader understands the mobile.</p>
  
  <p>The idea is when a employee comes to work he hover over the reader he gets clocked in.</p>
  
  <p>On github i found some solutions for reading the nfc with python:</p>

  <p>Maybe i don't understand it right but shouldn't i get a ID of the phone or able to write data to it or is it just a reader (but why does file transfer works over nfc)?</p>
  
  <p>Maybe i just need to buy a nfc-tag and use that for the clocking?</p>
