The tip jar is a time honored tradition at various establishments to honor outstanding service. Unfortunately today's consumer is less likely to carry around cash than in previous years. Just because it's plastic over paper for most nowadays doesn't mean that tips have gone by the wayside.
The Dipjar is a tip jar with a built-in credit card swiper. The swiper takes out a dollar per swipe so if one would like to give more money, it's entirely possible. The dollar amount is set so that restaurant owners cannot go in and change the amount for their stores.
The body of the Dipjar is made of aluminum while the top is made of plastic. This tip jar also has a built-in function for tracking the times of transactions and the speed for easy distribution among employees.
