title: How to use iBeacons?
body: <p>I have been viewing quite a few tutorials on iBeacons. I have a few questions though. I was wondering if it is possible for an iBeacon to collect data and transmit it to my app. And, how would I accomplish this?
  Do I have to modify the iBeacon itself or are there already some types of beacons that are able to collect data and transfer it to the app. I know this is a lot questions but please help me.</p>
  
  <p>Any suggestions or input is greatly appreciated.</p>
  
  <p>Thanks in advance!</p>
