title: How read/write tag with ACR122U connected to a Android tablet
body: <p>I'm using an ACR122U connected to my Android Tablet which hasn't a NFC antenna, so I connect via USB the ACR. It means that I can't use the standard library of Android to use that device.</p>
  
  <p>The ACS company, that provides the ACR, offers their own ACS Android Library in the next link:
  <a href="http://android.acs.com.hk/" rel="nofollow">http://android.acs.com.hk/</a></p>
  
  <p>It provides a .jar but I haven't found any API explaning how use it. They supply a manual with an API in a low level code. I'm not sure that API is fine with the Android library because I think that is previous.

  <p>My question is if someone can help me to read and write a tag using NDEF messages, like I did using the standard library of Android with the NFC Technology</p>
  
  <p>Thanks</p>
