With the changes that Turning Point made beginning in Fall
  2015, everyone will now get access to ResponseWare once you
  have established your Turning Point account and Redeemed
  your License.  This means that everyone will be able to
  answer Turning Point questions using any device that has a
  browser with access to the internet.  If you don't have a
  SmartPhone with internet access and/or don't choose to
  bring a laptop or tablet to your classes, you may choose
  to use a clicker instead. 

  Also, phone users can get an app for their phones instead
  of using a browser.  That info is here.

  Clicker Option:

  The QT clicker (white and black with keypad) or the all
  black QT2 clicker is available through the ASU Bookstore
  and also available online at the Student Store, which is
  at the bottom of the left-hand menu within your
  Turning Point Account.

  Used NXT clickers (white and black with screen), though no
  longer available through the ASU Bookstore, will work just
  as well as the QT clickers.

  Used XR clickers (either blue with screen or white/orange
  with screen), though no longer available through the ASU
  Bookstore, will work just as well as the NXT clickers.
