DipJar, which first hit the market in 2012, allows customers to use their credit card to leave gratuity. Now the company is gearing up to introduce a new model that lights up when a customer leaves a tip, alerting those around them.
The company says the new model was in response to customers not always knowing whether their tips were being received, but also wanting recognition for tipping.
The etiquette of who to tip and how much has become murky as the practice becomes more widespread.
