Square has had chip readers for a little while now and they are pretty cheap too --&gt; <a href="https:&#x2F;&#x2F;squareup.com&#x2F;shop&#x2F;reader" rel="nofollow">https:&#x2F;&#x2F;squareup.com&#x2F;shop&#x2F;reader</a> .  One of my favorite bars is already using it.  Why would someone switch away from square if they are happy with it and there is a cheap upgrade path to support chip readers?  Switching services potentially costs time...I can&#x27;t imagine people wanting to spend that time unless they were inherently unhappy with square.
