What is the difference between a sequence and a menu?

A Sequence directs a customer directly to web content.  When you tap the tag, you are taken to the assigned content.  It is possible to assign several different steps so that each time the tag is tapped, the user is taken to different web content with each tap in the specified order.

A Menu gives a customer options with configurable buttons.  The user can select different buttons that will surface different content.
