Netherlands company Margento maintains a mobile transaction service based on what it call “Data-over-Voice”, which essentially works the same as the French solution above – your phone transmits data via sound, which is read and decoded by a scanner at the point of sale. It has announced it is entering into a 50-50 joint venture with the services branch of multinational company Bertelsmann, Arvato Services. Margento and Arvato will be using the Data-over-Voice system for loyalty/coupon redemption, payments for products and services, balance top-up, mobile tickets, and electronic gift vouchers.
