"The relatively huge gap between the dining and other categories is because vendors in other categories have yet to develop a complete mobile payment environment compared to the dining category which the system was originally designed for," says Tzu-li Hu, a senior industry analyst with MIC.

“Moreover, physical retail outlets and credit card-issuing banks are two major sources Taiwanese consumers learn about mobile payments and therefore expanding their mobile payment availability will be strategically important for the mobile payment industry in Taiwan.”
