The Moby/5500 by Ingenico serves several use cases due to its mobile point-of-sale (mPOS) capabilities. It can be used by large retailers in retail stores, pop-up shops, and events with large crowds, or can be useful for micro-merchants in markets and home services. The Moby/5500 targets segments where traditional POS systems might not be practical. Its portability allows businesses to conduct transactions on the go, enhancing customer convenience and reducing queue times.
