Retail Point Of Sale abbreviated as RPOS. It is that device which is used in the retail selling of any product. It is used where an invoice is made at the end of any purchase. But it is not only that, when a customer walks into a store he not only comes to buy things and just leave. He expects the retailer to understand him and engage with him. RPOS can help the retailer serve the customer in a flexible manner to improve in-store connections. It can also help retailers to provide seamless and consistent brand experience.
