title: NFC eSE: editing nfcee_access.xml to allow access to NFC card emulating App
body: <p>I'm trying to make an App for LG Optimus 4x that will require it to emulate as a NFC tag. It's a simple boarding pass/ ticketing app. For that, I'm following this tutorial:</p>

  <p>I have the following confusions: </p>
  
  <p>I'm not sure about the NFC controller used by the device and the availability of embedded secure element. I have rooted the device and <code>/etc</code> contains the <code>nfcee_access.xml</code> file. So, I'm assuming the device has the embedded Secure Element. Please correct me if I'm wrong.</p>
  
  <p>Second, The <code>nfcee_access.xml</code> file already contains a long signer hex string saying "Google Wallet Release Signature". In order to enable access to my own app, do i still have to add another signer certificate for my app or the Google Wallet's signer certificate will work for my app too? Or should I just add my package name after this already existing Signer Certificate? </p>
  
  <p>If I have to add a new signer certificate, how can I get it exactly? </p>
