A new iPhone app called Dash is putting a positive spin on this old, negative phrase by trying to make paying your tab faster and easier.
We've all had the experience of dining at a busy restaurant, and when it comes time to pay the bill we can't seem to find our server. And depending on how big of a hurry we're in, it can ruin an otherwise great meal. Dash wants to change this by letting you decide when it's time to pay the bill and leave.
Dash works simply enough. Whenever you dine at a restaurant that accepts Dash payments, you tell your server at the beginning of the meal that you'll be paying with dash. Your phone with pair with software right there in the restaurant, and when you're ready to leave you just pay your bill with your phone.
Currently, Dash is being used in a limited trial in about two dozen restaurants in New York City, so I haven't seen a lot of documentation about how it actually works. My guess is that there is some sort of pre-authorization when you indicate that you'll be paying with Dash, which would protect restaurant owners.
