Abstract: A method and system for processing payment transaction at a computing device is provided. The method includes receiving a payment request at the computing device from a purchaser terminal, the payment request including purchaser information, determining whether payment information associated with the purchaser information exists at the computing device, and processing payment transaction using the payment information if it is determined that the payment information associated with the purchaser information exists at the computing device.

Abstract: Apparatuses and techniques relating to an augmented reality (AR) device are provided. The device for augmenting a real-world image includes a light source information generating unit that generates light source information for a real-world image captured by a real-world image capturing device based on the location, the time, and the date the real-world image was captured. The light source information includes information on the position of a real-world light source for the real-world image. The device further includes a shadow image registration unit that receives the light source information generated from the light source information generating unit. The shadow image registration unit generates a shadow image of a virtual object overlaid onto the real-world image based on the light source information generated from the light source information generating unit.
