The document proposes a mobile payment solution called Tip Safe that allows customers to pay their restaurant bill and add a tip using their phone. It works by providing customers with a barcode and number on their bill that they scan using the Tip Safe website or app, where they can categorize the payment and add a tip before paying securely with their phone. The payment would then be processed through the restaurant's existing NCR payment system. Restaurants and customers would benefit from the faster and more secure payment process compared to existing options. The company would make money by partnering with existing payment processors and charging restaurants a slightly lower transaction fee than competitors.
