Many people love to do online shopping just to save the time energy and of course many choose this option when they are in hurry. So online commerce is a new business strategy that draws potential customers to make purchase in virtual stores. And offline commerce is also a business strategy(combination of technology and manpower) that draws potential customers to make purchase in physical stores. As retail sector is undergoing many changes & online shopping is increasing because of the features it offers with many other benefits customer experience can be improved by bringing this online features into the offline retail i.e. O2O(online to offline). More than 80% of retail sales will still happen at physical locations in 2020. And despite the best efforts of Amazon.com just over 8% of retail sales happen online. This will not enrich the customer experience but this will take the retail sector to a next level with great convenience and innovation with the help of AR(augmented reality). To achieve this kind of environment this paper proposes a solution by immersing AR technology into the offline retail. The proposed solution allows the customers to purchase their product with ease in less time with help of a handheld device which is used by everyone now days like our smartphones etc. That device provides a 3d AR based interface that combines the online features and brick and mortar shopping. Customers/shoppers can browse the shelves and products just like in online shopping and can get the information about that product. The device or we can say the application which we used will act as a nexus between the traditional and online commerce., International Journal of Scientific Research in Computer Science Engineering and Information Technology, 2018, CSEIT183566
