title: Is it possible to send Pseudo-APDU commands while card is not present?
body: <p>I am using the <code>javax.smartcardio</code> package for developing smart card related applications. I want to send Pseudo ADPU commands to set my reader's LED / LCD status.</p>
  
  <p>I found that the only method to send APDU commands to reader/card is <code>CardChannel::transmit</code>, but it must be run on card present .</p>
  
  <p>Is it possible to send Pseudo-APDU commands while card is not present in the reader? what about the APDU commands? (Using Java)</p>
