title: Does host should increase ATC (Application Transaction Counter) (EMV tag 9F36) after unsuccessful transaction?
body: <p>The host update the ATC after success transaction and the counter on the ICC and in the host DB is the same in this moment.</p>
  
  <p>But, does host should increase/update the ATC in the own DataBase after not success transaction (for example after transaction with not correct PIN) because the counter on ICC is increased? 
  Or host shouldn't change the ATC after it.</p>
  
  <p>I didn't find answer into any EMV book.</p>
