Purpose This thesis – aims to propose a method to help financial institutions improve their customers’ convenience online and offline through a Bluetooth based App using the tool of a beacon. The emergence of smartphones in the 21st century and their increasing use makes it possible to search for information easily. Research design, data, and methodology – With the short-distance Bluetooth technology for smartphones, which finds users within a radius of 50m to provide the functions of message transmission and mobile payment, users can access information services and use mobile coupons in certain premises. Thus, beacon-based O2O technology has been developed. Results – This study offers a method of attracting customers through an O2O marketing strategy that overcomes the existing limitations of Web and Offline media. Conclusions –Since beacon technology has the advantage of more accurate positioning than GPS, financial institutions provide their product information for users through the basic function of a beacon, using an O2O (Online to Offline) marketing solution and, therefore, effectively enable customers to make relevant payments online and conduct their financial actions offline.
