“Worldwide, 400 million Maestro cards by the brand that Mastercard introduced thirty years ago are in circulation. Nevertheless, the successful card will soon be replaced by a new debit card under the Mastercard brand. The main reason is the rise of e-commerce.  According to Henri Dewaerheijd, country manager Belgium and Luxembourg, Mastercard and Maestro have always been two different brands with their proper payment network. “The Mastercard network is twice as large and offers more possibilities to process e-commerce transactions. Due to the enormous growth of e-commerce, especially in the past few months, the importance of that network has increased even more”, he told Belgian newspaper De Tijd.”
