Alipay R0 is an e-payment cash register integrated with the functions of digital payment, an ERP system and cloud business service, which is the first of its category. It targets the 60 million small merchants in China. Due to their small business volume and insufficient cash flow, they are unable to afford the costly traditional cash register and additional products for opening new business. Thereby, we developed a cost-effective all-in-one software and hardware solution for better experience.
