Whether it’s operating a single retail store or as part of a chain, the Point-of-Sales (POS) system is the center of the business operation, integrating all processes from a sales transaction. From inventory checks, customer purchase information, or keyed-in credit card payments, an efficient point-of-sales system plays a critical role in retail operation performance. Moreover, with the development of AIoT technology, a powerful POS server for self-service operations, such as with a kiosk or ATM, can integrate advanced surveillance systems with content and visual analysis.
