title: Android NFC scan time
body: <p>I am working with Android and ISO14443 type B tags and there is an issue that I am not able to solve. Hopefully someone can give a hint.</p>
  
  <p>When NFC setting of the phone are turned on, it starts sending REQA and REQB commands in order to discover if any tag is present. The issue is that by default this is done with a periodicity of 2 seconds and I would like to modify that time to make it shorter.</p>
  
  <p>I see that most apps maintain this scan period, but there are some apps such as TagInfo from NXP that reduce it to 250 ms. </p>
  
  <p>Among all information available for android NFC, I didn't find anything about tag scan time. </p>
  
  <p>Does someone know about this scan time? How is it possible to modify it?</p>
  
  <p>Thank you in advance.
