With the rapid growth of the global economy, the tourism industry has received increasing attention, the development prospects are bright, and the hotel industry is also developing rapidly. The construction of smart hotels is gradually on the agenda. At the same time, with the impact of mobile payments, traditional payment methods can no longer meet the smart needs of smart hotels. Payments such as WeChat Pay and Alipay have become the mainstream. At the same time, online payment and offline verification are also new forms of smart hotel payment. The current smart POS machines are based on the open Android system and integrate QR code scanning and printing functions to meet the smart payment needs of smart hotels.
