A study on a new bank card operation model—“Dual-account card”

With GDP per capita growing steadily in China´s large and medium cities, credit consumption steps into its rapid growth period. Base on an analysis of current bank card business model and its data processing flow, a novel operation model-dual-account card model is proposed. This model is a financial transaction security solution with good usability. To be compatible with current bank card system, it also enjoys a low upgrading cost. Dual-account card model allows 2 accounts in 1 card: the basic account is an income account; the external account is an expenditure account and the only account at risk. In an case study, some credit cards with their transaction records are randomly selected to build a data cube, in which, 5 customer groups with notable features are found by clustering. For each group, a new operating strategy is proposed to make this business more profitable.
