With Adson, customers get everything from a single source: a modern, user-friendly mobile card terminal ("EC terminal") with integrated 4G multi-SIM that dials into the strongest network throughout Europe, and a reliable service that is perfectly tailored to them. "With our low-cost and flexible flat rates, which really cover all costs including all transaction and card fees, we also create transparency and thus remove any fears of contact that still exist," Hövekamp adds.
