DJ Victor created a system that lets people make requests using their phones. They can also see what song is playing and view a list of most requested songs. The system has proven phenomenally successful.
At the start of an evening DJing, Victor passes out paper flyers containing a barcode link so everyone can access these features.
Here is an example of the flyers he passes out on all tables and the bar:
For a demo of what customers see on their phones, tap the 'CLUB DEMO' button.
Keep in mind you are viewing a demo only. In actual use, the words 'Club Demo' are replaced by the particular club name; the 'Most Requested Songs' are songs requested at that club; and the song shown as 'Now Playing' is, in fact, playing.
