title: How to format branching statements (while/if-else) in UML use case descriptions?
body: <p>How are branching statements supposed to be written in UML use case descriptions? Here is the situation I am modelling -</p>
  
  <p>An employee has to swipe a card through a card reader to clock into work. The system emits a sound signifying a read success or failure. If the read fails three times the user is given the option of entering their details manually into a PC.</p>
  
  <p>Here is the use case description I have made, it seems very awkward and unclear with all the if/elses. Is this the way use case descriptions are supposed to be written or is there a better method?</p>
